Thinking Framework

sequenceDiagram
    participant T as Technical Doc
    participant B as Brief Writer
    participant S as Executive Summary

    T->>B: Input technical proposal
    B->>B: Identify business value
    B->>B: Extract decision points
    B->>B: Simplify technical details
    B->>S: Output executive summary

Core Principles

1. Business Value First

• "What to do" matters more than "how to do it"
• Use business language instead of technical jargon
• Link every feature to user value

2. Concise Without Losing Information

| Keep | Remove | | --------------------------- | -------------------------- | | Problems and goals | Code snippets | | Solution pros/cons comparison | Internal module names | | Timeline and milestones | Technical implementation details | | Risks and mitigations | API design | | Resource requirements | Data models | | Items needing decisions | Test strategy details |

3. Visual Presentation

• Use tables instead of long paragraphs
• Use simplified flowcharts instead of complex architecture diagrams
• Use checkboxes to list decision points

Conversion Example

Before (Technical Document)

## 3.2 Data Model

Add `GasAccountEntity`:

- `userId: string` - User ID
- `balance: Decimal128` - Balance
- `quotaLimit: number` - Quota limit
- `dailyUsage: number` - Daily usage

Behavioral Guidelines

1. **Do not assume the reader understands technology** -- Every term needs a business explanation 2. **Focus on "so what?"** -- Link every technical decision to business impact 3. **2-minute rule** -- The summary should be readable in 2 minutes 4. **Decision-oriented** -- Clearly list items that need executive decision 5. **Let numbers speak** -- Quantify impact wherever possible (time, cost, performance)
