Problem-Solving Strategies for Engineers

PDCA Problem-Solving Implementation Guide 1. Record the Problem Before solving a problem, it must be clearly recorded. This section captures essential details: ✅ What? – Define the problem in simple terms. Example: "Machine downtime due to overheating." ✅ Where? – Specify the location where the problem occurs. Example: "Production Line 3." ✅ When? – Mention the time or frequency of occurrence. Example: "Every 3 hours during peak operation." ✅ Who? – Identify the person/team affected or responsible. Example: "Maintenance team and machine operators." --- 2. Analyze the Problem (Fishbone Diagram / Ishikawa Diagram) This step breaks down the root causes of the problem into six major categories: 1️⃣ Man (People) – Human-related issues such as skill gaps, fatigue, or errors. Example: "Operators lack training on temperature monitoring." 2️⃣ Machine (Equipment) – Issues related to machines, tools, or software. Example: "Cooling fan failure due to wear and tear." 3️⃣ Management (Policies & Supervision) – Leadership, procedures, and decision-making. Example: "No preventive maintenance schedule in place." 4️⃣ Method (Process & Procedures) – Work processes that may contribute to the problem. Example: "Inefficient lubrication process causing overheating." 5️⃣ Material (Raw Materials & Resources) – Issues with materials used in production. Example: "Low-quality lubricants used, causing excessive friction." 6️⃣ Milieu (Environment) – External factors like temperature, humidity, or workplace conditions. Example: "Hot working conditions increasing machine temperature." --- 3. Identify Root Causes (5 Whys Technique) After listing potential causes, use the 5 Whys method. Example: ❓ Why is the machine overheating? → "Cooling fan failure." ❓ Why did the fan fail? → "It was not replaced on time." ❓ Why was it not replaced? → "No preventive maintenance plan." ❓ Why is there no plan? → "Management did not prioritize it." ❓ Why did management not prioritize? → "Lack of awareness about maintenance importance." --- 4. Take Action (Corrective & Preventive Measures) This step focuses on fixing the issue and preventing recurrence by assigning responsibilities. ✅ What? – Define the action to be taken. Example: "Implement a preventive maintenance schedule for cooling fans." ✅ Who? – Assign ownership to individuals or teams. Example: "Maintenance Supervisor, John Doe." ✅ When? – Set a deadline for completion. Example: "By 30th September 2025." --- 5. Validate the Results After implementing corrective actions, assess whether the problem was effectively solved. ✅ Result Evaluation: Good, on target ✅ – The problem is fully resolved. Slightly improved ☑ – Some improvement but still needs work. Bad, off target ❌ – The issue persists. ✅ Standardization: Create a new standard if the solution is a best practice. Update the existing standard if adjustments are required. ✅ Approval: Score the effectiveness and obtain approval from an expert...

Stuck on a coding problem? Here’s how top engineers actually solve them. Whether you’re prepping for interviews or building real-world systems, it’s not just about writing code — it’s about solving problems intelligently. Here’s a 10-step mindset that transforms debugging into breakthroughs: 1. Understand the problem Restate it in your own words. Clarity first, code later. 2. Work through examples by hand Manual tracing helps uncover hidden logic. 3. Break it down Small steps → Simple code → Fewer bugs. 4. Pick the right approach Map it to known algorithms or problem patterns (greedy, sliding window, recursion, etc.) 5. Write pseudocode first Your thinking should be clear before your syntax is. 6. Code in chunks Build incrementally and test as you go. It’s okay, the random print statements are always going to help (just comment them out after ;)) 7. Test edge cases Empty inputs, large datasets, invalid values — test for chaos. 8. Optimize after it works First, get it working. Then, make it elegant and efficient. 9. Stay calm when stuck Take a break. Talk it out LOUD. Google concepts, not answers. Still doesn’t work? Try to get at least one test case. 10. Reflect after solving Ask: What did I learn? What pattern was this? Could I solve it faster next time? ⸻ 💬 Real talk: Being a good coder isn’t about avoiding bugs but about knowing how to find your way out of them.

The best advice I got as a junior engineer: 1. Make it work: In the initial stages, focus on creating a functional solution. Prioritise getting the core functionality up and running to establish a baseline. 2. Then make it right: Once the basic functionality is achieved, shift your focus to refining the code. Clean up your implementation, improve code structure, and adhere to best practices for better maintainability. 3. Then make it fast & pretty: After achieving functionality and code cleanliness, work on optimizing performance and enhancing the user interface. Ensure that the software runs efficiently and has a polished, user-friendly design. 4. Embrace Continuous Learning: Stay curious and committed to ongoing learning. Keep abreast of new technologies, tools, and methodologies to stay relevant and enhance your skills throughout your career. 5. Seek Feedback and Collaboration: Actively seek feedback from peers and experienced colleagues to improve your skills. Foster a collaborative environment that encourages open communication, leading to innovative solutions and a stronger team dynamic. 6. Prioritize Documentation: Document your code, processes, and decisions clearly. This not only aids in understanding your work later on but also helps team members comprehend and maintain the code, contributing to an efficient workflow. 7. Understand the Business Context: Go beyond technical skills and strive to understand the broader business context. Align your technical efforts with organizational goals to make your contributions more impactful and meaningful. 8. Practice Problem-Solving: Develop a problem-solving mindset by breaking down complex issues into manageable components. This approach not only makes problem-solving feasible but also helps in identifying root causes and fosters resilience in the face of technical challenges. 9. Prioritize Security and Reliability: Emphasize security and reliability in your work. Write secure code, ensure robustness in solutions, and prioritize testing to create software that not only functions well but is also resilient to potential vulnerabilities and failures. Remember, a well-rounded set of skills and attitudes will not only make you a proficient engineer but also contribute to a positive and productive work environment.

🛠️ One question I get asked often is: How do experienced technicians diagnose faults so quickly, sometimes in minutes, without running every test in the book? The answer lies in a mix of intuition, logic, and years of pattern recognition. Here’s what’s actually happening behind the scenes: 1️⃣ Sensory awareness → They listen to strange noises, feel vibrations, smell burning insulation, their senses are tuned like instruments. 2️⃣ Pattern memory → They’ve seen it before, not once, but dozens of times. And their brain stores those symptoms like mental flashcards. 3️⃣ Isolation technique → They rule out what’s working before chasing what’s not. This narrows the field, fast. 4️⃣ Start simple → They don’t jump to complex solutions. They check the basics first power, connections, settings, alignments. 5️⃣ Ask the right questions → Often, the operator holds the key. A simple, “When did this start?” or “What changed recently?” reveals more than a sensor scan. 6️⃣ Calm under pressure → They don’t panic. They pause, observe, and act methodically, even when the clock is ticking. Why does this matter beyond engineering? Because this troubleshooting mindset applies everywhere: → When leading teams → Solving business problems → Or making personal decisions under pressure The best problem-solvers don’t just rely on tools, they develop awareness, stay calm, and trust their process. So next time you face a complex challenge, don’t rush. Slow down. Ask the right questions. Start simple. And trust that every problem has a pattern, you just have to learn to see it.

Are you showing admiration for a problem? I listened to someone on the phone the other day, basically for the day, “admiring the problem”. If that whole 8 or so hours could have been spent on solution seeking, asking “what’s right with this?” the person and their team might be a little ahead. To move beyond this unproductive #mindset, here are some strategies people can adopt: 1. Reframe the Problem • Shift the focus from describing the problem to exploring opportunities for change. • Use solution-oriented language, such as “How might we…?” 2. Clarify the Desired Outcome • Define the goal or the ideal state you want to achieve. • Ask, “What does success look like?” 3. Break It Down • Deconstruct the problem into smaller, manageable pieces. • Address each part with specific actions. 4. Prioritize Action Over Analysis (Paralysis) • Set a time limit for discussing the problem, then transition to brainstorming solutions. • Encourage trying small, experimental solutions (e.g., prototyping in #designthinking). 5. Adopt a #Collaborative Approach • Engage diverse perspectives to generate ideas and build momentum. • Create an environment where everyone feels safe to contribute solutions. 6. Use Frameworks and Tools • Apply structured tools like root cause analysis, the 5 Whys, or SWOT analysis to understand and address the issue. • Visualize the path forward with a decision matrix or action plan. 7. #Empower Accountability • Assign ownership for tasks and follow up on progress. • Build systems that encourage responsibility, such as regular check-ins or deadlines. 8. Encourage a Bias Toward Experimentation • Shift from “getting it perfect” to “getting it started.” • View failures as learning opportunities. 9. Challenge Complacency • Ask tough questions to disrupt the cycle of inaction: • “What happens if we don’t solve this?” • “What’s one thing we could do right now to make progress?” 10. Leverage Emotional Intelligence • Identify emotional barriers, such as fear or frustration, that might keep people stuck. • Foster optimism and resilience in the face of challenges.

Problem Solving Tools Part 3 : 5Why (or Why-Why) Explained Developed by Sakichi Toyoda, the founder of Toyota, as part of the Toyota Production System; the 5 Why method is a powerful problem-solving technique. The basic concept involves asking "Why?" five times to uncover the root cause of a problem. How to Perform a 5 Why Analysis 1️⃣ Assemble a team: Bring together relevant experts to ensure a comprehensive analysis that the problem is looked from different aspects and expertise/angles. 2️⃣ Define the problem: Clearly state the issue you want to investigate. 3️⃣ Ask "Why?": Begin the chain of questioning, with each answer becoming the basis for the next "Why?". The "5" in 5 Why is not a strict rule. You may need fewer or more "Why?" questions to reach the root cause. But usually less than 3 Why's wont enable you to go deep into root cause. 4️⃣ Use Branching : Problems often have more than one root cause. In these cases, you can use branching to cover different causes your team identifies. So one why may have multiple branches, and branch also may have multiple branches like a tree. Branching allows for a more thorough exploration of problem and ensures clarity within the team. 5️⃣ Continue until root cause is found: This may take more or fewer than five "Why?" questions. Check each assumption in Gemba and dont ask further whys if Gemba verification fails. 6️⃣ Develop and implement solutions: Address the identified root cause, prepare a clearly worded action plan with responsible and dedline. Example Problem: Late delivery of repaired parts to customers ❓ Why is the delivery late? ➡️ Branch A: The repair process is stopped midway ➡️ Branch B: Shipping delays ❓ Why is the repair process stopped midway? ➡️ Because the data clerk has entered wrong information into the system ❓ Why has the clerk entered wrong information into the system ? ➡️ Because the labeling on the received packages was not fully unreadable ❓ Why was the labeling unreadable ? ➡️ Because labeling ink got smeared during handling ❓ Why labeling ink got smeared during handling ➡️ Because the label and ink quality is not good enough to prevent smear Benefits of 5 Why Analysis ✅ Comprehensive Problem-Solving: Addresses multiple facets of complex issues. ✅ Improved Root Cause Identification : Helps uncover multiple root causes that might be missed in a linear approach. ✅ Team Engagement : Promotes broader participation and diverse perspectives in problem-solving. ✅ Visualization : Can be represented as a tree diagram, making it easier to understand and communicate the analysis . By using the 5 Why method, teams can conduct a more thorough analysis of complex problems, leading to more effective solutions and continuous improvement in processes.

Most engineers don't fail at fixing I&I problems.   They just accept the first solution presented. Why? Because it feels safer to: • Go with the consultant's $2M replacement plan  • Avoid questioning the "expert" recommendation  • Sign off on wholesale system replacements  • Choose the solution that "no one gets fired for" But here's the truth: NOT questioning the default solution is the riskiest move you can make. Remember that mountain community I&I study we completed? ↳ 90% of their WWTP flow was I&I ↳ Treatment plant operating at 9x necessary capacity   ↳ Initial recommendation: Complete system replacement   ↳ Our finding: 60% of problems in just 2 areas The difference? We questioned everything. https://lnkd.in/dY_eYZa4 Instead of accepting the standard "replace it all" approach, we asked: "What if we just fixed the 40% causing 90% of the problem? Result: Same outcome, 80% less cost. The best engineers aren't afraid to push back on expensive solutions. Challenge. Every. Single. Assumption. Next time a consultant hands you a massive replacement plan, ask: "Where's the data showing we need to replace everything?" Who cares if you ruffle feathers? The day you start demanding targeted solutions is the day you start being a true advocate for your community. What "standard practice" are YOU ready to challenge in 2025?

How often do we rush to solutions, only to realize later that we misunderstood the problem?  In project management, this is a common trap. The pressure to deliver quickly often overshadows the need to deeply understand the problem. But here's the truth: asking the right questions first comes the best solutions.  Here's a simple formula to guide you:   Understand + Analyze + Create = Great Solutions 1. Understand: Take the time to define the problem clearly. This is the foundation of effective problem-solving. Without it, you risk solving the wrong issue. 2. Analyze: Use techniques like the "5 Whys" or a Problem Tree to uncover root causes. These methods help you see beyond the surface and identify what's going on. 3. Create: Combine creativity with structure. Approaches like Design Thinking allow you to explore innovative solutions while staying focused on the problem at hand. The projects that succeed aren't the ones that move the fastest—they're the ones that solve the right problems. So, let's rethink how we approach challenges. Let's prioritize understanding over urgency. What's your go-to method for defining problems in your projects? Do you have a favourite framework or technique? Let's discuss. → Found this helpful?

💥 Here's a common and costly mistake made by engineers and researchers (and many other professions): 🤦🏽♂️ You think you know the problem you are trying to solve, but you haven't written it down clearly and haven't invited candid feedback from others. 😳 It's amazing how something can seem to make perfect sense in your head, but when you're forced to write it down, all sorts of questions and logical gaps appear. 😱 Plus, getting feedback can be scary. 😬 But even scarier is spending years developing and testing something, only later to discover that the problem you put all your time and energy into solving wasn't a real or compelling problem, or was framed in a way that made the solution inconsequential and trivial. 🎯 Here's how you can avoid this mistake: ✍🏽 Write down the problem as clearly as you can. Be concise, but include some specifics and key constraints. After that, get candid feedback from a few people you trust, at least some of whom are outside your team or bubble. 🔁 Revise and repeat. Drafting a good problem statement will take time, usually with many revisions and aha moments along the way! Often your early brainstorming, testing, and development will further refine the problem statement. 🚀 Once the problem is solidified, you can really go deep on a solution! As the adage goes: a problem well stated is half solved.
