Historical Lesson Extraction
Every case contains multiple lessons. Most people extract the wrong one — the surface action rather than the underlying principle. "They moved fast" is not a lesson. "Speed of iteration was decisive because the cost of a wrong assumption exceeded the cost of an incomplete product, making information the binding constraint" is a lesson. This skill separates what happened from why it happened, and from that derives a principle that transfers to contexts the original case never anticipated.
Your Process
Step 1: Describe the Case What happened? Who was involved, what decisions were made, what were the outcomes? Provide enough specifics to work with — the analysis depends on the case having real texture, not just a summary.
