This course commences at 9:30 AM and ends at 6PM each day, with breaks scheduled throughout.

Even with the best quality systems and training, problems can happen. Root cause analysis (RCA) describes a wide range of approaches, tools, and techniques used to uncover causes of problems. For engineers, this could be applied to failure analysis in engineering and maintenance, quality control problems, safety performance, and computer systems or software analysis. The goal of RCA is to identify the origin of a problem using a systematic approach and determine:

• What happened
• Why it happened
• How to reduce the likelihood that it happens again
• How to launch a solution implementation plan

This three-day course provides a collaborative and dynamic learning environment that affords the participant the ability to perform RCA on real-world problems and overlay solutions to the problems. Each RCA tool is presented in an easy-to-follow structure: a general description of the tool, its purpose and typical applications, the procedure when using it, an example of its use, a checklist to help you make sure it is applied properly, and different forms and templates.

The examples used can be tailored to many different industries and markets, including manufacturing, robotics, bioengineering, energy, and pressure technology. The layout of this course has been designed to help speed participants’ learning through short videos depicting well-known scenarios for analysis in class. Course Materials (included in purchase of course):  Digital course notes via ASME’s Learning Platform

Engineering Problem Solving ¶

Some problems are so complex that you have to be highly intelligent and well-informed just to be undecided about them. —Laurence J. Peter

Steps in solving ‘real world’ engineering problems ¶

The following are the steps as enumerated in your textbook:

Collaboratively define the problem

List possible solutions

Evaluate and rank the possible solutions

Develop a detailed plan for the most attractive solution(s)

Re-evaluate the plan to check desirability

Implement the plan

Check the results

A critical part of the analysis process is the ‘last’ step: checking and verifying the results.

Depending on the circumstances, errors in an analysis, procedure, or implementation can have significant, adverse consequences (NASA Mars orbiter crash, Bhopal chemical leak tragedy, Hubble telescope vision issue, Y2K fiasco, BP oil rig blowout, …).

In a practical sense, these checks must be part of a comprehensive risk management strategy.

My experience with problem solving in industry was pretty close to this, though encumbered by numerous business practices (e.g., ‘go/no-go’ tollgates, complex approval processes and procedures).

In addition, solving problems in the ‘real world’ requires a multidisciplinary effort, involving people with various expertise: engineering, manufacturing, supply chain, legal, marketing, product service and warranty, …

Exercise: Problem solving

Step 3 above refers to ranking of alternatives.

Think of an existing product of interest.

What do you think was ranked highest when the product was developed?

Consider what would have happened if a different ranking was used. What would have changed about the product?

Brainstorm ideas with the students around you.

Defining problems collaboratively ¶

Especially in light of global engineering , we need to consider different perspectives as we define our problem. Let’s break the procedure down into steps:

Identify each perspective that is involved in the decision you face. Remember that problems often mean different things in different perspectives. Relevant differences might include national expectations, organizational positions, disciplines, career trajectories, etc. Consider using the mnemonic device “Location, Knowledge, and Desire.”

Location : Who is defining the problem? Where are they located or how are they positioned? How do they get in their positions? Do you know anything about the history of their positions, and what led to the particular configuration of positions you have today on the job? Where are the key boundaries among different types of groups, and where are the alliances?

Knowledge : What forms of knowledge do the representatives of each perspective have? How do they understand the problem at hand? What are their assumptions? From what sources did they gain their knowledge? How did their knowledge evolve?

Desire : What do the proponents of each perspective want? What are their objectives? How do these desires develop? Where are they trying to go? Learn what you can about the history of the issue at hand. Who might have gained or lost ground in previous encounters? How does each perspective view itself at present in relation to those it envisions as relevant to its future?

As formal problem definitions emerge, ask “Whose definition is this?” Remember that “defining the problem clearly” may very well assert one perspective at the expense of others. Once we think about problem solving in relation to people, we can begin to see that the very act of drawing a boundary around a problem has non-technical, or political dimensions, depending on who controls the definition, because someone gains a little power and someone loses a little power.

Map what alternative problem definitions mean to different participants. More than likely you will best understand problem definitions that fit your perspective. But ask “Does it fit other perspectives as well?” Look at those who hold Perspective A. Does your definition fit their location, their knowledge, and their desires? Now turn to those who hold Perspective B. Does your definition fit their location, knowledge, and desires? Completing this step is difficult because it requires stepping outside of one’s own perspective and attempting to understand the problem in terms of different perspectives.

To the extent you encounter disagreement or conclude that the achievement of it is insufficient, begin asking yourself the following: How might I adapt my problem definition to take account of other perspectives out there? Is there some way of accommodating myself to other perspectives rather than just demanding that the others simply recognize the inherent value and rationality of mine? Is there room for compromise among contrasting perspectives?

How ‘good’ a solution do you need ¶

There is also an important aspect of real-world problem solving that is rarely articulated and that is the idea that the ‘quality’ of the analysis and the resources expended should be dependent on the context.

This is difficult to assess without some experience in the particular environment.

How ‘Good’ a Solution Do You Need?

Some rough examples:

10 second answer (answering a question at a meeting in front of your manager or vice president)

10 minute answer (answering a quick question from a colleague)

10 hour answer (answering a request from an important customer)

10 day answer (assembling information as part of a trouble-shooting team)

10 month answer (putting together a comprehensive portfolio of information as part of the design for a new $200,000,000 chemical plant)

Steps in solving well-defined engineering process problems, including textbook problems ¶

Essential steps:

Carefully read the problem statement (perhaps repeatedly) until you understand exactly the scenario and what is being asked.

Translate elements of the word problem to symbols. Also, look for key words that may convey additional information, e.g., ‘steady state’, ‘constant density’, ‘isothermal’. Make note of this additional information on your work page.

Draw a diagram. This can generally be a simple block diagram showing all the input, output, and connecting streams.

Write all known quantities (flow rates, densities, etc.) from step 2 in the appropriate locations on, or near, the diagram. If symbols are used to designate known quantities, include those symbols.

Identify and assign symbols to all unknown quantities and write them in the appropriate locations on, or near, the diagram.

Construct the relevant equation(s). These could be material balances, energy balances, rate equations, etc.

Write down all equations in their general forms. Don’t simplify anything yet.

Discard terms that are equal to zero (or are assumed negligible) for your specific problem and write the simplified equations.

Replace remaining terms with more convenient forms (because of the given information or selected symbols).

Construct equations to express other known relationships between variables, e.g., relationships between stoichiometric coefficients, the sum of species mass fractions must be one.

Whenever possible, solve the equations for the unknown(s) algebraically .

Convert the units of your variables as needed to have a consistent set across your equations.

Substitute these values into the equation(s) from step 7 to get numerical results.

Check your answer.

Does it make sense?

Are the units of the answer correct?

Is the answer consistent with other information you have?

Exercise: Checking results

How do you know your answer is right and that your analysis is correct?

This may be relatively easy for a homework problem, but what about your analysis for an ill-defined ‘real-world’ problem?

Chapter 6 - Engineers as Problem Solvers

Published online by Cambridge University Press:  05 February 2015

• Engineers as Problem Solvers

Evers, Rush, and Berdrow (1998) identi-fy numerous disconnects between skills acquired in college and those required of the workplace. Among the most important skills that ABET Inc., the primary engineering accreditation institution in the United States, has identified for the preparation of engineers are the abilities to identify, formulate, and solve workplace engineering problems and to function on multidisciplinary teams. Learning to solve workplace problems is an essential learning outcome for any engineering graduate. Every engineer is hired, retained, and rewarded for his or her ability to solve problems. However, engineering graduates are ill prepared to solve complex, workplace problems (Jonassen, Strobel, & Lee, 2006).

Problem solving from a cognitive perspective has been the primary focus of my research for the past decade and a half. My theory differs from traditional theories of problem solving in that I argue there are different kinds of problems that vary between contexts. The kinds of problems that practicing engineers solve are different from the problems that most undergraduate science, technology, engineering, and mathematics (STEM) students learn to solve. In most undergraduate classes, students learn to solve textbook problems that are constrained and well structured, with known solution paths and convergent answers (capstone courses are an exception). Workplace problems, on the other hand, tend to be ill structured and unpredictable because they possess conflicting goals, multiple solution methods, non-engineering success standards, non-engineering constraints, unanticipated problems, distributed knowledge, and collaborative activity systems (Jonassen et al., 2006). Learning to solve classroom problems does not effectively prepare engineering graduates to solve workplace problems. To prepare engineering graduates, it is necessary to articulate the differences between educational problems and workplace problems. To do that, I first describe how problems vary.

3 What is Problem Solving?

Chapter table of contents, what is problem solving.

• What Does Problem Solving Look Like?

Developing Problem Solving Processes

Summary of strategies, problem solving:  an important job skill.

The ability to solve problems is a basic life skill and is essential to our day-to-day lives, at home, at school, and at work. We solve problems every day without really thinking about how we solve them. For example: it’s raining and you need to go to the store. What do you do? There are lots of possible solutions. Take your umbrella and walk. If you don’t want to get wet, you can drive, or take the bus. You might decide to call a friend for a ride, or you might decide to go to the store another day. There is no right way to solve this problem and different people will solve it differently.

Problem solving is the process of identifying a problem, developing possible solution paths, and taking the appropriate course of action.

Why is problem solving important? Good problem solving skills empower you not only in your personal life but are critical in your professional life. In the current fast-changing global economy, employers often identify everyday problem solving as crucial to the success of their organizations. For employees, problem solving can be used to develop practical and creative solutions, and to show independence and initiative to employers.

what does problem solving look like?

The ability to solve problems is a skill at which you can improve.  So how exactly do you practice problem solving? Learning about different problem solving strategies and when to use them will give you a good start. Problem solving is a process. Most strategies provide steps that help you identify the problem and choose the best solution. There are two basic types of strategies: algorithmic and heuristic.

Algorithmic strategies are traditional step-by-step guides to solving problems. They are great for solving math problems (in algebra: multiply and divide, then add or subtract) or for helping us remember the correct order of things (a mnemonic such as “Spring Forward, Fall Back” to remember which way the clock changes for daylight saving time, or “Righty Tighty, Lefty Loosey” to remember what direction to turn bolts and screws). Algorithms are best when there is a single path to the correct solution.

But what do you do when there is no single solution for your problem? Heuristic methods are general guides used to identify possible solutions. A popular one that is easy to remember is IDEAL [Bransford & Stein [1] ] :

IDEAL is just one problem solving strategy. Building a toolbox of problem solving strategies will improve your problem solving skills. With practice, you will be able to recognize and use multiple strategies to solve complex problems.

What is the best way to get a peanut out of a tube that cannot be moved? Watch a chimpanzee solve this problem in the video below [Geert Stienissen [2] ].

Problem solving is a process that uses steps to solve problems. But what does that really mean? Let's break it down and start building our toolbox of problem solving strategies.

What is the first step of solving any problem? The first step is to recognize that there is a problem and identify the right cause of the problem. This may sound obvious, but similar problems can arise from different events, and the real issue may not always be apparent. To really solve the problem, it's important to find out what started it all. This is called identifying the root cause .

Example: You and your classmates have been working long hours on a project in the school's workshop. The next afternoon, you try to use your student ID card to access the workshop, but discover that your magnetic strip has been demagnetized. Since the card was a couple of years old, you chalk it up to wear and tear and get a new ID card. Later that same week you learn that several of your classmates had the same problem! After a little investigation, you discover that a strong magnet was stored underneath a workbench in the workshop. The magnet was the root cause of the demagnetized student ID cards.

The best way to identify the root cause of the problem is to ask questions and gather information. If you have a vague problem, investigating facts is more productive than guessing a solution. Ask yourself questions about the problem. What do you know about the problem? What do you not know? When was the last time it worked correctly? What has changed since then? Can you diagram the process into separate steps? Where in the process is the problem occurring? Be curious, ask questions, gather facts, and make logical deductions rather than assumptions.

When issues and problems arise, it is important that they are addressed in an efficient and timely manner. Communication is an important tool because it can prevent problems from recurring, avoid injury to personnel, reduce rework and scrap, and ultimately, reduce cost, and save money. Although, each path in this exercise ended with a description of a problem solving tool for your toolbox, the first step is always to identify the problem and define the context in which it happened.

There are several strategies that can be used to identify the root cause of a problem. Root cause analysis (RCA) is a method of problem solving that helps people answer the question of why the problem occurred. RCA uses a specific set of steps, with associated tools like the “5 Why Analysis" or the “Cause and Effect Diagram,” to identify the origin of the problem, so that you can:

Once the underlying cause is identified and the scope of the issue defined, the next step is to explore possible strategies to fix the problem.

If you are not sure how to fix the problem, it is okay to ask for help. Problem solving is a process and a skill that is learned with practice. It is important to remember that everyone makes mistakes and that no one knows everything. Life is about learning. It is okay to ask for help when you don’t have the answer. When you collaborate to solve problems you improve workplace communication and accelerates finding solutions as similar problems arise.

One tool that can be useful for generating possible solutions is brainstorming . Brainstorming is a technique designed to generate a large number of ideas for the solution to a problem. The goal is to come up with as many ideas as you can, in a fixed amount of time. Although brainstorming is best done in a group, it can be done individually.

Depending on your path through the exercise, you may have discovered that a couple of your coworkers had experienced similar problems. This should have been an indicator that there was a larger problem that needed to be addressed.

In any workplace, communication of problems and issues (especially those that involve safety) is always important. This is especially crucial in manufacturing where people are constantly working with heavy, costly, and sometimes dangerous equipment. When issues and problems arise, it is important that they be addressed in an efficient and timely manner.  Because it can prevent problems from recurring, avoid injury to personnel, reduce rework and scrap, and ultimately, reduce cost and save money; effective communication is an important tool..

One strategy for improving communication is the huddle . Just like football players on the field, a huddle is a short meeting with everyone standing in a circle.   It's always important that team members are aware of how their work impacts one another.  A daily team huddle is a great way to ensure that as well as making team members aware of changes to the schedule or any problems or safety issues that have been identified. When done right, huddles create collaboration, communication, and accountability to results. Impromptu huddles can be used to gather information on a specific issue and get each team member's input.

"Never try to solve all the problems at once — make them line up for you one-by-one.” — Richard Sloma

Problem solving improves efficiency and communication on the shop floor. It increases a company's efficiency and profitability, so it's one of the top skills employers look for when hiring new employees.  Employers consider professional skills, such as problem solving, as critical to their business’s success.

The 2011 survey, "Boiling Point? The skills gap in U.S. manufacturing [3] ," polled over a thousand manufacturing executives who reported that the number one skill deficiency among their current employees is problem solving, which makes it difficult for their companies to adapt to the changing needs of the industry.

Tips for Solving Engineering Problems Effectively

Problem solving is the process of determining the best feasible action to take in a given situation. Problem solving is an essential skill for engineers to have. Engineers are problem solvers, as the popular quote says:

“Engineers like to solve problems. If there are no problems handily available, they will create their own problems.” – Scott Adams

Engineers are faced with a range of problems in their everyday life. The nature of problems that engineers must solve differs between and among the various disciplines of engineering. Because of the diversity of problems there is no universal list of procedures that will fit every engineering problem. Engineers use various approaches while solving problems.

Engineering problems must be approached systematically, applying an algorithm, or step-by-step practice by which one arrives at a feasible solution. In this post, we’ve prepared a list of tips for solving engineering problems effectively.

#1 Identify the Problem

Evaluating the needs or identifying the problem is a key step in finding a solution for engineering problems. Recognize and describe the problem accurately by exploring it thoroughly. Define what question is to be answered and what outputs or results are to be produced. Also determine the available data and information about the problem in hand.

An improper definition of the problem will cause the engineer to waste time, lengthen the problem solving process and finally arrive at an incorrect solution. It is essential that the stated needs be real needs.

As an engineer, you should also be careful not to make the problem pointlessly bound. Placing too many limitations on the problem may make the solution extremely complex and tough or impossible to solve. To put it simply, eliminate the unnecessary details and only keep relevant details and the root problem.

#2 Collect Relevant Information and Data

After defining the problem, an engineer begins to collect all the relevant information and data needed to solve the problem. The collected data could be physical measurements, maps, outcomes of laboratory experiments, patents, results of conducted surveys, or any number of other types of information. Verify the accuracy of the collected data and information.

As an engineer, you should always try to build on what has already been done before. Don’t reinvent the wheel. Information on related problems that have been solved or unsolved earlier, may help engineers find the optimal solution for a given problem.

#3 Search for Creative Solutions

There are a number of methods to help a group or individual to produce original creative ideas. The development of these new ideas may come from creativity, a subconscious effort, or innovation, a conscious effort.

You can try to visualize the problem or make a conceptual model for the given problem. So think of visualizing the given problem and see if that can help you gain more knowledge about the problem.

#4 Develop a Mathematical Model

Mathematical modeling is the art of translating problems from an application area into tractable mathematical formulations whose theoretical and numerical analysis provides insight, answers, and guidance useful for the originating application.

To develop a mathematical model for the problem, determine what basic principles are applicable and then draw sketches or block diagrams to better understand the problem. Then define and introduce the necessary variables so that the problem is stated purely in mathematical terms.

Afterwards, simplify the problem so that you can obtain the required result. Also identify the and justify the assumptions and constraints in the mathematical model.

#5 Use Computational Method

You can use a computational method based on the mathematical method you’ve developed for the problem. Derive a set of equations that enable the calculation of the desired parameters and variables as described in your mathematical model. You can also develop an algorithm, or step-by-step procedure of evaluating the equations involved in the solution.

To do so, describe the algorithm in mathematical terms and then execute it as a computer program.

#6 Repeat the Problem Solving Process

Not every problem solving is immediately successful. Problems aren’t always solved appropriately the first time. You’ve to rethink and repeat the problem solving process or choose an alternative solution or approach to solving the problem.

Bottom-line:

Engineers often use the reverse-engineering method to solve problems. For example, by taking things apart to identify a problem, finding a solution and then putting the object back together again. Engineers are creative , they know how things work, and so they constantly analyze things and discover how they work.

Problem-solving skills help you to resolve obstacles in a situation. As stated earlier, problem solving is a skill that an engineer must have and fortunately it’s a skill that can be learned. This skill gives engineers a mechanism for identifying things, figuring out why they are broken and determining a course of action to fix them.

Problem Solving in Mechanical Engineering With Real World Examples

• Mechanical Engineering

Mechanical engineering is all about solving problems by using science and math. Engineers have to come up with better designs and improve how things are made. They make sure everything works well and lasts long. It’s important because they need to know a lot about their field and think both creatively and logically to find solutions to real problems.

For instance, they might work on making heating and cooling systems use less energy, find ways to cut down on waste when making products, or create new materials for planes and spaceships. These examples show how crucial mechanical engineers are in making technology and industries better.

In simpler terms, mechanical engineers are like problem-solving wizards. They use their deep knowledge and smart thinking to tackle challenges, like making a car engine that uses less fuel or a machine that makes fewer errors. They’re always learning and inventing to make sure the things we use every day are the best they can be.

This is key because their work helps us save money, be safer, and even protect the environment. It’s how they play a big part in pushing technology forward and keeping industries running smoothly.

Understanding Fundamental Principles

In mechanical engineering, it’s crucial to really get thermodynamics, materials science, and how to analyze structures. Knowing these core ideas helps you figure out how forces and materials work together, how energy moves and changes, and how to make sure structures are strong enough to handle different kinds of pressure.

When dealing with complicated systems, you break them down to understand how they work under different situations. For example, when choosing materials, you look closely at their strength, how much they can bend, and how well they conduct heat to make sure they will work well and last a long time. Thermodynamics helps make energy systems work better and use less power. Every solution is carefully made using these ideas to make sure the engineering designs do what they’re supposed to and are safe.

As an example, when building a bridge, engineers will use materials science to pick the right steel that can support the weight of cars over time without bending too much. They’ll apply thermodynamics to design any moving parts, like a drawbridge, to work efficiently with minimal energy waste. By focusing on these principles, engineers make sure the bridge is not only functional, allowing people to cross safely, but also stands the test of time.

Analyzing Complex Systems

To really get how complex machinery works, engineers take it apart to look at each piece. This helps them see how all the parts fit together and make the machine do its job. They start by figuring out where the system begins and ends, then they take a closer look at the smaller parts, like the sensors and motors, and the computer brain that controls everything.

Engineers use special tools and tests, like checking what could go wrong and how likely it is (that’s called FMEA), running computer models, and seeing how changes affect the system. By doing all this, they make sure the machine is safe, reliable, and works well because they’ve checked everything carefully, not left it to luck.

It’s important that they do this because it helps prevent accidents and breakdowns. For example, think about a car: if engineers didn’t test all the parts, like brakes and airbags, we wouldn’t trust them to keep us safe on the road. So, they use these tools to make sure everything is in top shape. This kind of detailed work means that when you use something like a car or a dishwasher, it’s been checked to work properly and safely.

Innovating in Product Design

Creating new and better product designs starts with really understanding how current products work. Mechanical engineers look at these products in detail to figure out how they can make them work better, use less energy, and give people a better experience when using them.

The first step is to carefully study what the product is supposed to do, how people use it, and where it can be improved. Engineers have to take apart complicated parts and processes to spot opportunities for new ideas. They use practical engineering knowledge to make designs that are not just better, but also cost less and are better for the environment. They make sure every part of the new product has a reason to be there and helps make the product both new and useful.

Being committed to making these kinds of advances is a big part of what mechanical engineering is all about in product design.

For example, when engineers worked on a new blender, they saw that the old design was hard to clean. They redesigned the blades to be detachable, which made cleaning easier and the blender more efficient. This change also saved materials, making the blender more eco-friendly.

This kind of thoughtful redesign shows how engineers can make our everyday products better.

Optimizing Manufacturing Processes

In manufacturing, engineers focus on improving the process to achieve faster production, reduced waste, and cost savings. They analyze production methods, examining data and observing operations to identify bottlenecks and inefficiencies. Strategies such as lean manufacturing or Six Sigma are employed to optimize operations and enhance overall efficiency.

Improvements can be made by rearranging machine placement to minimize material movement, implementing proactive maintenance practices to prevent breakdowns, and introducing new technologies like robots. Additionally, engineers work on optimizing the timing of supply deliveries to minimize storage costs. These deliberate actions lead to smarter and more cost-effective manufacturing processes, giving companies a competitive edge.

Ensuring Quality and Reliability

After improving how things are made, it’s crucial to make sure the products are of high quality and can be relied upon. To do this, it’s essential to have a well-thought-out plan for checking the quality and making sure it’s consistent.

Engineers need to create detailed tests that really show what conditions and pressures the products will face in the real world. For example, they might use Failure Mode and Effects Analysis (FMEA) to find and fix possible weaknesses before they cause problems. They also keep an eye on the production process using Statistical Process Control (SPC) to ensure everything stays the same.

Moreover, they use reliability engineering to figure out how to make products last longer. This is all about cutting down on mistakes and making sure the product is as good as it can be, which makes customers happy and maintains the manufacturer’s good name.

To give a specific example, a car manufacturer might use crash tests to simulate real-life accidents. This helps them understand how the car would perform and what they need to improve to ensure passenger safety. By doing this, they not only meet safety standards but also build trust with their customers who know the vehicles are tested thoroughly.

To wrap things up, solving problems in mechanical engineering isn’t simple—it’s a detailed task that involves really understanding the basics, figuring out complicated machinery, being creative when making products, making sure manufacturing is as good as it can be, and always aiming for the highest quality and dependability. It’s vital that all these pieces work together to tackle the tough problems we see in the real world. Mechanical engineers must think things through step by step and apply what they know to keep coming up with new and better ways to move technology forward and make industries run more smoothly.

For example, when engineers work on a new car engine, they need to know exactly how each part works. They must come up with smart designs that make the engine more powerful without using more fuel. They also have to refine the way the engine is built so that the factory can make it without wasting time or materials. Plus, they have to test the engine over and over to make sure it will last a long time and won’t break down. This kind of detailed work is what pushes us ahead, making cars more efficient and reliable for everyone.

The Problem Solving Steps all Engineers Should Know

Imagine walking into a room, everyone is clamoring for answers and after a few moments you know exactly what everyone should do to fix the problem.

You deal with problems on a daily basis as an Engineer but sometimes you run into the situation where you solve the wrong problem, or senior engineers get frustrated with how long it's taking to complete a task - perhaps they gave you some vague problem statement and when you asked for some direction it was still high level because it should be "obvious".

I think where people get caught is the Senior engineers giving out tasks aren't necessarily looking to walk you through a solution, they want a problem to go away, they want to spend as close to zero brain cells on the problem (at this point in time). So your job is to make it go away and not to use their brain cycles.

But this is counter intuitive, if I don't know where to start or I take too long then that will also be frustrating since the problem will still be there.

Correct. So you are caught in between a rock and a hard place. But it's not the worst and we can certainly equip ourselves with the skills we need to handle these situations.

What's the situation?

Problem Solving and reducing our "mean-time to solve". There's a spectrum of problems one can consider and if you realize this you can see that more complex problems do require more time to solve - there's an "expected" time to solve. So you want to perform in such a way that you are below this line as much as is practicable.

I've worked in Engineering for over a decade now and I can tell you that for sure there are specific tricks to solving particular problems specific to the industry, company, field, technology, etc. You gain these by purely time. Working on problems and solutions in that area. This is why experience is king - but it is also overrated sometimes.

Someone with 5 years more experience may not be very good and if you only looked at the number of years you would be none the wiser.

So how can we overcome this hurdle and forget the number of years we've worked and just perform better?

Use the book 10+1 Steps to Problem Solving: An Engineers Guide.

Here I created simple steps to follow that looks at a more birds-eye view but is so practical you can apply it to any situation.

But this isn't some "one-size fits all" methodology, nor is it "how do I calculate the potential energy in this craft", "how do you enable this features in this software". Don't get it twisted.

But it does help formalize your approach, use the right mindset and ask the right questions at the various stages of problem solving.

What's wrong with Steps to Problem Solving lists out there? They are mostly correct, but the primary issue is they are so generic and have little practicality. They lay out steps around identification of the problem, analysis, breaking it down to small bits, evaluating. But more often than not they spend half the time talking about implementation, working out the kinks, timing, etc.

This presents 2 problems:

It is super slow

It is solution focused

I'm not saying you shouldn't plan out your solutions and have implementation plans, timings, schedules, documentation - you need these (at the solution stage). But when you plan out how you are going to try to fix something and spend all this time pondering - you could have simply tried and moved on.

You either fixed it or you got more data.

You iterate faster through your questions, quick testing of the obvious things, getting eyes on the situation in the correct way, checking your fundamentals and proceeding from there. (These are still in the first three steps by the way).

The rest of the steps are still focused on going deeper into the rabbit hole to solve your problems. This is when you are stuck, for hours, days, weeks!

So what are the steps?

Here's direct extract of the index:

The Question

The Obvious

Check Yourself

The RTFM Protocol

What about the Environment?

Phone-A-Friend

The Secret Step

The book goes on to explain each of these steps and provide a checklist style summary at the end of each. You can practically use this as a framework to approach problems, particularly tricky ones so that you can reduce the average amount of time you spend fixing things. There's real examples from easy to difficult ones covered so you gain context on how to fix.

I really wanted to help as many people as I can with this so I actually made the book completely free. You can get online access and read the whole thing from my website here .

It will require you create an account but other than that you are good.

At the time of this writing only the first 2 chapters are available, but you are getting early access as the book isn't set to release until the 4th Quarter of this year! (In time for Christmas).

You can register to get notified when the release is coming out so you can be first in line to get your own copy.

What's the advantage of problem solving this way?

So if you remember to the opening of this article we did cover some of the pain points and frustrations that can happen in an engineering career. So think of it this way, if you can consistently solve problems and make things go away, or better yet, things seem to get fixed faster when you are around - then you'll be wanted around.

This tends to have a compounding effect where you help others solve their problems simply by understanding this method and asking the right questions to get them to their own answer, and now people want you on bigger projects.

You do this and gain more responsibility and then now you have the foundation for increasing your pay, your role and your impact. (There's challenges here of course but I will have courses and free content to address these). You can become one of the "go to" engineers in your company.

Every Engineer should be aware of these problem solving steps.

This course presents the fundamentals of object-oriented software design and development, computational methods and sensing for engineering, and scientific and managerial applications. It cover topics, including design of classes, inheritance, graphical user interfaces, numerical methods, streams, threads, sensors, and data structures. Students use Java ® programming language to complete weekly software assignments.

How is 1.00 different from other intro programming courses offered at MIT?

1.00 is a first course in programming. It assumes no prior experience, and it focuses on the use of computation to solve problems in engineering, science and management. The audience for 1.00 is non-computer science majors. 1.00 does not focus on writing compilers or parsers or computing tools where the computer is the system; it focuses on engineering problems where the computer is part of the system, or is used to model a physical or logical system.

1.00 teaches the Java programming language, and it focuses on the design and development of object-oriented software for technical problems. 1.00 is taught in an active learning style. Lecture segments alternating with laboratory exercises are used in every class to allow students to put concepts into practice immediately; this teaching style generates questions and feedback, and allows the teaching staff and students to interact when concepts are first introduced to ensure that core ideas are understood. Like many MIT classes, 1.00 has weekly assignments, which are programs based on actual engineering, science or management applications. The weekly assignments build on the class material from the previous week, and require students to put the concepts taught in the small in-class labs into a larger program that uses multiple elements of Java together.

7 Engineering Challenges Design Thinking Can Help Solve

• 19 Jan 2023

Several challenges face the engineering industry. Addressing them requires innovative solutions and structured processes, such as design thinking.

If you’re an engineer who wants to develop business skills , here's an overview of design thinking and seven engineering challenges it can help solve.

What Is Design Thinking?

Design thinking is one of the most effective approaches to problem-solving. It’s a solutions-based methodology focused on human-centered design and observing problems with empathy.

In the online course Design Thinking and Innovation , Harvard Business School Dean Srikant Datar structures the process using a four-stage framework. The stages are:

In the clarification stage, you observe a situation or challenge without bias and frame your findings in the form of a problem statement.

“Before you begin to generate innovative solutions for your own design problem, you must always think hard about how you’re going to frame that problem,” Datar says in the course.

Reframing the problem as a question is an excellent way to do this. For example, using "how might we" instead of "the problem is" can encourage empathy in the design process and shift your mindset toward potential solutions.

These questions are particularly important when considering empathetic design. According to the Harvard Business Review , engineers who put themselves in their audience's shoes while designing often develop innovative products . By understanding your audience’s unexpressed needs, you can effectively leverage your technical knowledge to create innovative solutions to previously unknown problems.

Once you've made your observations, you can explore potential solutions. The ideate stage is for divergent thinking—the process of exploring as many ideas as possible. It involves:

• Finding and categorizing similarities in users' pain points
• Considering the resources available to you and how you can use them to solve a problem
• Brainstorming potential solutions

Creativity and an open mind are vital at this stage. As you explore ideas, they can highlight other problems you were unaware of.

The development stage focuses on turning your ideas into workable prototypes. For ideas to be innovative, they must be both new and useful ; many, though creative, aren't feasible.

"As you prototype concepts in phase three, you may discover results that force you to return to phases one and two to reframe your question," Datar says in Design Thinking and Innovation .

This iteration can occur in any of the four stages because each involves a different level of exploration that highlights new problems, questions, or solutions. This isn't cause for discouragement.

"Do not think of this as a setback,” Datar says in the course. “Iterating on solutions is a normal and expected result of design thinking.”

Design thinking’s ultimate objective is finding effective, workable solutions. The implementation phase involves finalizing developments and communicating their value to stakeholders.

This final stage can be challenging for many engineers. Since their work is so technical, it’s sometimes difficult for stakeholders to understand their impact on the organization. As a result, engineers should develop effective communication skills to ensure their ideas are implemented.

The Importance of Design Thinking in Engineering

Design thinking is a valuable skill for engineers to learn for several reasons. For one, engineering positions are among the most common occupations requiring design thinking skills .

Since engineers are often responsible for solving complex problems, it’s easy to get lost in the details and set creative problem-solving skills aside. Creativity in business is beneficial because it:

• Encourages innovation
• Boosts productivity
• Allows for adaptability
• Fosters growth

Leveraging design thinking skills to pursue innovation not only helps professionals find creative solutions but identify business opportunities , evaluate market needs , and design new products and services.

Engineers’ responsibilities can vary. Whether creating new products or maintaining existing ones, engineering revolves around design . For this reason, a systematic approach is highly valuable when encountering industry challenges.

7 Engineering Challenges Design Thinking Can Solve

Some of the challenges engineers often face include:

• Identifying obscure problems
• Overcoming cognitive fixedness
• Designing sustainable innovations
• Addressing the skilled labor shortage
• Encouraging diversity
• Keeping up with advancing technology
• Overcoming status-quo bias

Here’s an overview of how design thinking can help solve these problems.

1. Identifying Obscure Problems

Engineers often encounter problems that are difficult to identify. As a result, it can be easy for them to jump to conclusions based on preexisting knowledge of a design or situation. Datar discourages this in Design Thinking and Innovation .

"Whenever you have a difficult problem, you tend to solve the fringes of it,” Datar says. “But try and go for the most important part that you need to solve."

For example, if you're trying to remove a major obstacle preventing a project’s completion, you might be tempted to search for a cause equal in scope to its impact. However, some of the biggest design problems can be caused by something as simple as a misplaced hyphen or a loose screw. Often, the best approach is to consider the bigger picture. Is there anything in the design you don't understand?

The clarification stage in the design thinking framework encourages you to obtain insights through unbiased observation. An effective tool to accomplish this is journey mapping , which involves creating a chronological visual timeline of everything you know about a problem.

According to Design Thinking and Innovation , the three steps to developing a journey map are:

• Creating observations about the user's journey
• Writing those observations on a timeline
• Organizing the observations into different stages

Creating a timeline of events can help identify when a problem occurs, as well as what precedes and follows it. This can enable you to narrow down its cause.

2. Overcoming Cognitive Fixedness

Cognitive fixedness is a mindset that assumes there's just one way to accomplish tasks. It considers every situation through the lens of past decisions. Thinking "if it worked in the past, it'll work now" is easy to follow, especially in the engineering industry, where replicating past successes is often the best way to proceed.

For example, while new technology trends can succeed in the market because of their innovative features, incorporating those features into an existing design might not be feasible—and even prevent you from meeting critical deadlines. Furthermore, in areas with high risk to human life—such as submarine design—it may be advisable to incorporate technology that’s proven effective before creating something new.

While caution is important, cognitive fixedness can prevent innovation, resulting in obsolescence. You must strike a balance between the operational and the innovation worlds.

The difference between the two worlds is described in Design Thinking and Innovation :

• The operational world represents a business’s routine procedures.
• The innovation world facilitates open-endedly exploring ideas.

Although the operational world is important, it can result in cognitive fixedness and prevent ideas’ progression. If you're struggling to overcome cognitive fixedness—whether your own or someone else's—consider why there's an unwillingness to change to determine the next steps.

3. Designing Sustainable Innovations

Climate change is a pressing issue impacting businesses around the globe . An increasing number of organizational leaders are addressing it by focusing on the triple bottom line . According to the HBS Online course Sustainable Business Strategy , the triple bottom line considers:

• Profit: Satisfying shareholders and producing a profit
• People: Impacting society in a positive, measurable way
• The planet: Making a positive impact on the environment

By reframing problems and pursuing workable solutions that don't sacrifice profit, you can effectively incorporate sustainability into business strategies .

4. Addressing the Skilled Labor Shortage

The United States is experiencing a shortage of engineers , which has put a strain on employers hoping to hire qualified candidates in a shrinking market.

Consider how you'd approach this challenge from a design thinking perspective. Clarifying the problem might highlight opportunities you didn't previously think of. For instance, companies such as Google and Microsoft have invested in science, technology, engineering, and math (STEM) education , enabling more people to pursue careers in those industries.

Other companies have sought ways to attract engineering talent. It can be easy to draw candidates by raising salaries or increasing benefits, but many engineers aren't comfortable working for organizations that harm the environment. Your firm should consider adopting a sustainable business strategy that could benefit the planet and attract qualified applicants.

5. Encouraging Diversity

Engineering has historically been a male-dominated field. One of the primary causes of this imbalance is the workplace stereotype that STEM careers are masculine. This has resulted in implicit—and often direct—discouragement of women from pursuing STEM careers.

In the context of design thinking, clarifying and reframing the problem might result in questions like, "How can we empower more women to pursue STEM careers?"

Through exploring potential solutions, you may discover that encouraging and empowering a diverse population to pursue engineering can help address other challenges, such as the skilled labor shortage.

6. Keeping Up with Advancing Technology

Technology is continuously advancing; companies that fail to adapt might get left behind. For example, Blackberry was once one of the fastest-growing smartphone companies in the world. Yet, its products became obsolete when the company refused to adopt touch-screen technology. This resulted in Blackberry losing 90 percent of its market share between 2009 and 2013.

Design thinking encourages continual awareness to avoid these downward trends. Learning how to recognize opportunities and communicate them to others can prevent a business from falling behind.

7. Overcoming Status-Quo Bias

Resistance to change doesn't just occur within an organization—it happens among customers, too. This is known as status-quo bias , which is a challenge you must address during implementation.

The challenge is how to retain existing customers while appealing to the current market and acquiring new ones. Avoid assuming users will understand a design change you’ve implemented just because it makes sense to you.

According to Datar in Design Thinking and Innovation , you should consider three views during the implementation phase:

• The developer's view: The designer with knowledge and understanding of a design's utility and benefits
• The neutral view: Someone who doesn't have a preexisting opinion about the design
• Stakeholders' view: Existing customers and users who have existing opinions based on the status quo

Learning how to overcome status-quo bias is critical to successful innovation.

If you can’t solve the problem, go for a walk!

When interviewing for the software engineer position at LiLz, Eric asked me the following question:

"With your background and experience, you could be getting a high paying cushy job at one of the tech giants, doing software architecture or some such high level thing. Why join a tiny startup and write low level product code?"

Why indeed.

Almost twenty years ago, I went through the rigors of getting a Bachelor of Mathematics with a Computer Science major at the University of Waterloo, graduating with distinction (though just barely). I spent the first seven years of my career working at a fintech startup in San Francisco (most of it remotely from Japan), part of the fairly impressive team of engineers who previously worked at Amazon, Google, Microsoft, along with some talented fresh grads some of whom would later found successful companies of their own (and failed companies, like your's truly). I worked across the stack, from building high performance services with in-process databases that server stock trading data, to complex portfolio visualizations and management UIs. I always had an interest in and critical eye for usability, so naturally ended up gravitating towards the frontend.

Eventually I left to start my own company, and lead tech and product as CTO, and so have experience with the very raw reality of trying to build something useful and commercially viable from scratch, while at the same time trying to maximize the productive output of a small engineering team, in a sustainable manner that doesn't sacrifice the longterm growth and well-being for short-term bursts of output. In the world where mass market consumer tech was increasingly causing addiction, anxiety, robbing people of their attention span and selling their eyeball-hours to the highest bidder, we wanted to flip the relationship between people and tech back to what we thought was normal: make tech a simple tool for people to improve their daily lives. For our startup specifically we focused on meal planning and chores. We did not reach profitability, but did survive for four years, which in startup land is a decent run.

I then joined another startup to use all my front-end-heavy software development experience to step a level above regular product work, and design and build the holy grail of frontend stacks. Most developers have a wish list for their stack. For frontend stacks, it typically looks like this:

I wish I could use the same language in the frontend and backend (F# in our case)

I wish we could use the same codebase for the web and mobile apps

I wish it was easy to do the right thing (e.g. any button that fires an async action by default comes with a spinner attached) and hard to do the wrong thing (e.g. give user no visual feedback that "something is happening")

I wish I could just simply subscribe on backend data and never have to do another raw API call

I wish I had powerful and expressive DSL for each subdomain of frontend development (styling, component tree structuring, etc)

and so on. We wanted it all, and we had a very ambitious CTO with a healthy disregard for the limitations of reality, and his direction was clear: "We're hiring you to build the holy grail of frontend stacks".

We thought it would take us a year, in reality it took about five, though a good portion of that time was spent building out actual apps that used the progressively improving versions of our holy grail stack. To say that the work was challenging would be quite the understatement. The more requirements you want to satisfy, the more the constraints associated with each requirement come into conflict with each other. Eventually the myriad of constraints is so restrictive that finding solutions becomes an exercise of slowly and persistently rolling a giant boulder up the mountain. But after all the struggles, we succeeded, and though pride isn't something I experience naturally, it's probably reasonable to say that I was proud of how close to the goal we managed to get.

Over the five years of building the holy grail of frontend stacks, two things became apparent to me.

First, spending each and every day on super challenging problems, finding narrow tunnels within the multi-dimensional spiderwebs of constraints, is just not sustainable for me. I find that at least half of the weekly workload needs to be of the "comfortably coding at a healthy pace" to sustain challenging problem solving for the rest of the week. Very-hard-problems-all-of-the-time is suitable for a cushy research job at a university, with little pressure to deliver on tight deadlines, but combined with a startup mentality, this mode of work becomes hugely taxing.

Second, I sorely missed product development. My motivation circuitry has always been based on delivering useful features to human users, usually by iteratively improving a product that I personally care about. And having just finished a marathon of language/framework/stack design and development, I felt like I was long overdue for some good old product building.

Finding the next challenge proved to be difficult. As you may be able to tell from the above, I grew progressively more opinionated about just about every aspect of my work. So any company that I'd join would have to satisfy some very stringent constraints.

A huge part of doing good work is saying "no" to things. I knew what kind of problems and products I didn't want to work on. I knew what technologies I didn't want to touch. I knew what sort of work environments didn't suit me. I didn't want "just a job", I wanted a job where I could feel meaning in what I did, honestly care about the product and the work every day, and be surrounded by people who are both competent workers but also good human beings with lives outside of work. I wanted to be held to a high standard, and be able to do the same to my colleagues. I didn't want bureaucracy. I didn't want overtime for the sake of signaling one's dedication to the company — I have long ago learned that doing great programming work for eight hours per day tires you out so much that any additional hours spent are useless (or your day has a lot of bureaucratic downtime, like meetings, which lets your brain rest).

Talk about a multi-dimensional web of constraints, eh? You can imagine that the number of choices that satisfied a reasonable subset of my constraints was quite limited.

I came across a posting for a software engineer job at LiLz on LinkedIn. In the country where most startups end up in Tokyo, seeing one defiantly headquartered in Okinawa put a huge smile on my face. Gutsy. I like that. They also seemed to take pride in the quality of their work, both the user facing product, and the code that powers it. It's surprising how rarely such a commitment is stated explicitly, even though every company out there has a generic "values" page on their website. There was something genuine about LiLz, and I ended up submitting an application.

After applying I looked into the company in greater detail, reading the website, news articles, the company blog. The more I read the more impressed I felt. A product that users seem to love? Check. A small team that punches far above their weight? Check. Humble, down to earth, doing great work with no glamorous but empty-sounding proclamations about changing the world? Check.

Based on the data I was gathering, the image of Onishi-san, the CEO, was particularly impressive and unexpected. His management style is "supporting my colleagues, empowering them to do their best work". In a world where there's plenty of managers who feel like their job is to boss their underlings around, this was a breath of fresh air. The man's the CEO of the company, yet his photo isn't plastered at the top, but is lost at the end of the second row of LiLz employee introduction slide. He focuses on solving real problems that real people have right now, not entertains some grand theoretical visions. He understands that saying "no, not now" is how you stay focused on the problem at hand and polish your product without spreading the team too thin. Even small, simple things, like his statement that going for a walk is a great way to get unstuck when solving problems, resonated deeply with me. This is the person who sets the company culture? Man, count me in!

The first interview I had was with Kuba, the CTO. Two hours went by quickly, and the discussion was engaging. I got to ask a vast number of questions, from the particulars of the software stack, to the philosophical approach to software development, to questions about the camera hardware, the current roadmap, the company's financial health. He responded to everything straightforwardly, with good humor and complete honesty.

In preparation for subsequent interviews, I read other team members' blog posts about how they joined LiLz. The posts were overflowing with humanity — everybody had their own style, their own background, their own way of telling their story. They talked about the work-life balance that working for LiLz afforded them. I strived for this when trying to build my own company — empowering people to do excellent work during regular business hours, and then go home on time and enjoy their private lives. And now here I was reading about a startup with a small team, having reached product-market fit, accomplishing just that! I felt a little jealous, but more importantly, I really wanted to be part of it!

Interviews rolled on. My friends were joking that by the time I get an offer, I would have met all the employees and all their extended families. But jokes aside, I really appreciated the amount of care they put into selecting candidates to join their team. I've been on the hiring side of the table many times before, and understand that the importance of finding the right people cannot be underestimated.

It's been almost a month since my first day. I'm happy to report that so far I have not discovered any broken promises or red flags. During my onboarding, I've spent a week full of random sporadic tech discussions with Kuba, and was reassured by how he manages to both have strong opinions and a flexibility to discuss and adjust them when necessary. Tech decisions at LiLz are aimed to address fundamental business needs in a healthy, straightforward manner, rather than to stroke one engineer's ego or personal preferences. Communication is clear, careful, and friendly. And for the first time in years, I'm once again doing product work, coding at a healthy pace, discussing how to move the product forward, how to deliver more value, having fun. It's still a little surreal that I somehow found a company that satisfied my copious constraints to this degree, but here I am, hopefully to do great work for years to come!

Title: audio decoding by inverse problem solving.

Abstract: We consider audio decoding as an inverse problem and solve it through diffusion posterior sampling. Explicit conditioning functions are developed for input signal measurements provided by an example of a transform domain perceptual audio codec. Viability is demonstrated by evaluating arbitrary pairings of a set of bitrates and task-agnostic prior models. For instance, we observe significant improvements on piano while maintaining speech performance when a speech model is replaced by a joint model trained on both speech and piano. With a more general music model, improved decoding compared to legacy methods is obtained for a broad range of content types and bitrates. The noisy mean model, underlying the proposed derivation of conditioning, enables a significant reduction of gradient evaluations for diffusion posterior sampling, compared to methods based on Tweedie's mean. Combining Tweedie's mean with our conditioning functions improves the objective performance. An audio demo is available at this https URL .
