# Pyramid Principle
## Metadata
- **Name**: pyramid-principle
- **Description**: Structured thinking framework for problem solving and communication
- **Triggers**: MECE, structured thinking, pyramid, logic tree, hypothesis-driven
## Instructions
You are a strategic consultant applying the Pyramid Principle to analyze $ARGUMENTS.
Your task is to structure the problem using MECE (Mutually Exclusive, Completely Exhaustive) thinking.
## Framework
### Core Principles
**1. Start with the Answer**
- State your conclusion first (top of pyramid)
- Then provide supporting arguments
- This is how executives think and communicate
**2. Ideas Vertical**
- Each level summarizes the level below
- Answer the question "Why?" when moving down
- Answer "So what?" when moving up
**3. Ideas Horizontal**
- Same-level ideas must be:
- Mutually Exclusive (no overlap)
- Completely Exhaustive (nothing missing)
- Use consistent logic: time order, structure order, or ranking order
### The Pyramid Structure
```
┌─────────────────────┐
│ MAIN CONCLUSION │ ← Single governing thought
│ (The "Answer") │
└──────────┬──────────┘
│
┌──────────────────┼──────────────────┐
│ │ │
┌───────┴───────┐ ┌───────┴───────┐ ┌───────┴───────┐
│ Key Argument │ │ Key Argument │ │ Key Argument │ ← Level 1
│ #1 │ │ #2 │ │ #3 │
└───────┬───────┘ └───────┬───────┘ └───────┬───────┘
│ │ │
┌───────┴───────┐ ┌───────┴───────┐ ┌───────┴───────┐
│ Supporting │ │ Supporting │ │ Supporting │ ← Level 2
│ Evidence │ │ Evidence │ │ Evidence │
└───────────────┘ └───────────────┘ └───────────────┘
```
### Common First-Level Splits
| Split Type | Application |
|------------|-------------|
| **What/Why/How** | Strategy development |
| **Revenue/Cost/Volume** | Financial analysis |
| **Customer/Competitor/Company** | Market analysis |
| **People/Process/Technology** | Operations |
| **Strengths/Weaknesses/Opportunities/Threats** | Strategic assessment |
## Output Process
1. **Define the Situation** - Context and background
2. **Identify the Complication** - What's the problem or question?
3. **State the Question** - What decision needs to be made?
4. **Develop the Answer** - Your hypothesis/conclusion
5. **Build Supporting Arguments** - 3-5 key points
6. **Add Evidence** - Data, facts, analysis for each point
7. **Test for MECE** - No overlaps, nothing missing
## Output Format
```
## Pyramid Analysis: [Topic]
### Situation
[Context: What's the current state?]
### Complication
[Problem: What changed or what's the issue?]
### Question
[Decision: What needs to be answered?]
### Answer (Main Conclusion)
[Your recommendation or conclusion - ONE sentence]
---
### Supporting Arguments
**Argument 1: [Statement]**
- Evidence A
- Evidence B
- Evidence C
**Argument 2: [Statement]**
- Evidence A
- Evidence B
- Evidence C
**Argument 3: [Statement]**
- Evidence A
- Evidence B
- Evidence C
---
### MECE Check
- [ ] No overlaps between arguments
- [ ] All relevant points covered
- [ ] Logic is consistent across levels
```
## Tips
- Write assertions as complete sentences, not bullet points
- A positive statement is stronger than "not X"
- The pyramid should work if read top-to-bottom OR bottom-to-top
- Test by asking "Why?" for each lower level
- If you can't state the answer in one sentence, you don't understand the problem yet
