Best Practices

最佳实践

Deep Reasoning Process

深度推理流程

  1. Question Assumptions
    • What are we taking for granted?
    • What if those assumptions are wrong?
    • Are there alternative framings?
  2. Consider Second-Order Effects
    • What happens after this change?
    • What does this enable/prevent in the future?
    • What precedent does this set?
  3. Think in Systems
    • How does this affect the whole system?
    • What are the feedback loops?
    • What are the unintended consequences?
  4. Evaluate Reversibility
    • Is this decision reversible?
    • What's the cost to change later?
    • Should we defer this decision?
  5. Seek Diverse Perspectives
    • What would different roles think?
    • What are blind spots?
    • Who disagrees and why?
  1. 质疑假设
    • 我们默认了什么？
    • 如果这些假设不成立会怎样？
    • 有没有其他解读方式？
  2. 考虑二阶效应
    • 这个变更会带来什么后续影响？
    • 它会在未来促成/阻碍什么？
    • 它会树立什么先例？
  3. 系统思维
    • 这会如何影响整个系统？
    • 有哪些反馈循环？
    • 会有哪些意外后果？
  4. 评估可逆性
    • 这个决策可逆吗？
    • 后续变更的成本是多少？
    • 我们应该推迟这个决策吗？
  5. 寻求多元视角
    • 不同角色的人会怎么看？
    • 有哪些盲区？
    • 谁会反对，原因是什么？

Communication Principles

沟通原则

  • Be Clear and Direct: State recommendation upfront, explain reasoning concisely
  • Acknowledge Trade-offs: Every decision has costs; be honest about downsides
  • Provide Context: Why this matters, what's at stake
  • Enable Decision-Making: Present options clearly, recommend but don't dictate
  • Document Reasoning: Record key factors, alternatives, and assumptions
  • 清晰直接：先说明建议，再简洁解释理由
  • 坦诚权衡：每个决策都有成本，如实说明弊端
  • 提供上下文：说明重要性与风险点
  • 赋能决策：清晰呈现选项，给出建议但不强加
  • 记录理由：记录关键因素、替代方案及假设
