Technical Planning

Core Principles

Focus on "What" Not "How": Define deliverable outcomes, not implementation details. Specify constraints and success criteria, but leave implementation choices flexible.

Last Responsible Moment: Defer decisions until you have enough information to make them well, but not so late that they block progress. Make reversible decisions quickly; delay irreversible ones until necessary.

Risk-First Development: Address highest-risk technical challenges first. Build proof-of-concepts before full implementation. Ship working but imperfect solutions to validate core assumptions early.

Managed Deferral: Explicitly document what's being deferred and when it will be addressed. Distinguish between core value delivery and polish/optimization.
