The expert doesn't just know many models—they know when to apply each one. Using the wrong model is often worse than using no model at all. **Core Principle:** The map is not the territory. Choose the map that best serves your journey. ## When to Use - Facing a new problem type - Current approach isn't working - Multiple stakeholders suggest different frameworks - Deciding how to structure analysis - Teaching others which tools to use - Building decision-making processes Decision flow: ``` Facing a problem? → Have you identified the problem type? → no → CLASSIFY THE PROBLEM FIRST → Does your usual model fit? → no → CONSIDER ALTERNATIVES → Are you using a model by habit? → yes → QUESTION THE FIT ``` ## Problem-Model Matching ### Step 1: Classify the Problem ```markdown ## Problem Classification Problem: [Describe the problem] Problem dimensions: | Dimension | Assessment | |-----------|------------| | Predictability | Can outcomes be predicted? [High/Medium/Low] | | Complexity | How many interacting parts? [Simple/Complicated/Complex] | | Time horizon | When do consequences matter? [Immediate/Short/Long] | | Reversibility | Can decisions be undone? [Easily/With difficulty/Not at all] | | Information | How much do you know? [Complete/Partial/Minimal] | | Stakeholders | Who's af
