Problem Solving and Application

TL;DR

Problem solving is about breaking down complex challenges into manageable steps to find effective solutions. You'll learn to identify the real problem, plan your approach, execute it, and then check your work. This systematic method helps you tackle any problem efficiently and effectively.

1. The Mental Model

Think of problem solving like building with LEGOs: you first understand what you want to build, then you gather the right pieces, assemble them step-by-step, and finally, you check if it looks like the picture. It’s a structured way to turn a big challenge into small, achievable tasks.

2. The Core Material

Problem solving isn't just about finding an answer; it's about having a reliable process to get there. This process helps you manage complexity and avoid getting stuck.

2.1 Understanding the Problem

Before you can solve anything, you need to know exactly what the problem is. This often involves asking questions and gathering information. Don't jump to solutions too quickly!

• Identify the core issue: What's the main thing you need to fix or achieve?
• Gather information: What data, facts, or constraints are relevant?
• Define success: How will you know if your solution worked?

2.2 Devising a Plan

Once you understand the problem, it's time to strategize. This is where you brainstorm possible solutions and pick the best path forward.

• Brainstorm solutions: Think of multiple ways to address the core issue. Don't filter ideas yet.
• Evaluate options: Consider the pros and cons, resources needed, and potential risks for each solution.
• Select the best approach: Choose the solution that seems most feasible and effective. Break it down into smaller, actionable steps.

2.3 Executing the Plan

This is where you put your chosen solution into action. Follow the steps you outlined, but be ready to adapt if things don't go exactly as planned.

• Follow your steps: Systematically work through your plan.
• Monitor progress: Keep an eye on how things are going. Are you on track?
• Adjust as needed: If a step isn't working, pause, re-evaluate, and change your approach.

2.4 Reviewing the Solution

After you've implemented your solution, it's crucial to check if it actually worked and if there's anything you can learn for next time.

• Verify success: Does your solution meet the success criteria you defined earlier?
• Analyze what worked/didn't: What went well? What could have been better?
• Document findings: Note down your solution and any lessons learned.

Here’s a diagram to visualize this process:

3. Worked Example

Let's say you're building a new shelf, but when you try to screw in the final piece, the holes don't line up.

1. Understand the Problem:

   • Core Issue: Holes in shelf panel and support bracket don't align, preventing assembly.
   • Information: Shelf panel has pre-drilled holes, bracket has pre-drilled holes. Screws won't go in.
   • Success: Shelf is fully assembled and sturdy.

2. Devise a Plan:

   • Brainstorm:
     • Force the screws (bad idea, could damage wood).
     • Drill new holes (might weaken wood, look messy).
     • Check if I'm using the wrong parts/orientation.
     • Measure hole distances on both parts.
   • Evaluate: Forcing is risky. Drilling is a last resort. Checking parts/orientation is simple and non-destructive. Measuring will confirm the issue.
   • Selected Approach: First, double-check the instruction manual and the orientation of the parts. If they're correct, measure the distance between the holes on both pieces to confirm misalignment.

3. Execute the Plan:

   • You consult the manual and realize you've put the bracket on upside down. You flip it.
   • Now the holes align perfectly. You insert and tighten the screws.

4. Review the Solution:

   • Verify success: The shelf is assembled, stable, and the screws are in.
   • Analyze: The problem wasn't a manufacturing defect but a simple error in following instructions/orientation. The solution was effective.
   • Document: Remember to carefully check part orientation and instructions before assuming a defect.

4. Key Takeaways

• Always clearly define the problem before trying to solve it.
• Breaking a big problem into smaller steps makes it less daunting.
• Don't be afraid to brainstorm multiple solutions, even if some seem wild at first.
• Be flexible; your initial plan might need adjustments during execution.
• Always review your solution to ensure it worked and to learn for future problems.
• Taking time to understand the problem upfront saves time and effort later.

Common Mistakes to Avoid:
- Jumping directly to a solution without fully understanding the problem.
- Sticking rigidly to a plan even when it's clearly not working.
- Getting discouraged and giving up when facing initial difficulties.
- Not verifying if your solution actually solved the original problem.

5. Now Try It

Think of a common problem you've faced recently, either at home, work, or school (e.g., a printer not working, a cooking recipe going wrong, a computer error). Spend about 15 minutes applying the four-step problem-solving process (Understand, Plan, Execute, Review) to that specific situation. Write down your steps for each stage. Success looks like you having a clear, step-by-step written plan that either led to a solution or provided clear insights into why the problem was difficult.
