What does it mean that proactive schema evolution?

Do not wait for failure to update schemas — regularly review and refine them.

Example: An engineering manager reviews her leadership schema quarterly, not because anything went wrong, but because she's learned from three months of new experience. She asks: What assumptions am I making about how my team works? Which ones have I actually tested? She finds she's still operating on 'senior engineers don't need check-ins' — a belief inherited from her first manager. She updates it before it costs her a resignation.

Try this: Pick one schema you rely on daily — how you make decisions, how you manage time, how you evaluate people. Set a 30-minute calendar event for this week. During that block, write down the schema's core assumptions. For each assumption, ask: When did I last test this? What evidence would change my mind? What has changed in my environment since I adopted this belief? If you find even one outdated assumption, you've just prevented a future failure.
