🧠 Thinking Frameworks
A comprehensive toolkit of 180 thinking frameworks across 15 categories. Use this skill whenever you need to apply structured thinking to a problem — whether analyzing, deciding, creating, evaluating, or coaching.
When to Use This Skill
- Solving complex or ambiguous problems
- Making high-stakes decisions under uncertainty
- Brainstorming or generating creative solutions
- Evaluating evidence, arguments, or research
- Strategic planning and competitive analysis
- Coaching or teaching structured thinking
- Diagnosing root causes of failures
- Understanding system dynamics and feedback
- Identifying and countering cognitive biases
- Designing products, services, or experiences
Core Workflow
Step 1: Classify the Situation
Use the Cynefin Framework (Dave Snowden) to determine what kind of problem you're facing:
| Domain |
Characteristics |
Approach |
| Clear |
Obvious cause-effect, best practices exist |
Apply known frameworks directly |
| Complicated |
Cause-effect requires expertise/analysis |
Use analytical + strategy frameworks |
| Complex |
No predictable cause-effect, emergent |
Use systems thinking + experimentation |
| Chaotic |
No cause-effect, crisis |
Act first (OODA Loop), then stabilize |
| Confused |
Don't know which domain you're in |
Decompose the problem; gather more context |
Step 2: Select Frameworks by Purpose
| Purpose |

Step 3: Apply the Framework
- State the problem clearly before selecting a framework
- Choose 2-3 complementary frameworks — the power is in combination (Munger's Latticework principle)
- Walk through the framework step by step — don't just name it, use it
- Show your reasoning — make the framework application explicit and transparent
- Evaluate the output — does the framework's output match reality? If not, try a different lens
Step 4: Multi-Framework Analysis (Advanced)
For complex problems, stack frameworks deliberately:
Problem → [Classify: Cynefin] → [Diagnose: 5 Whys + Fishbone]
→ [Generate: SCAMPER + Six Hats] → [Evaluate: Pre-Mortem + Second-Order Thinking]
→ [Decide: Decision Matrix] → [Communicate: Pyramid Principle]
