Define measurable key results for objectives before acting,
Define measurable key results for objectives before acting, so that reality can provide corrective feedback rather than post-hoc rationalization.
Why This Is a Principle
Derives from Generative Externalization (externalization is generative), Illusion of Explanatory Depth (self-assessment is unreliable until articulated), and Knowledge that exists only in tacit form degrades without (tacit knowledge degrades). Grove's OKR framework and the lesson's core claim that measurement enables feedback loops lead to this prescription: specify observable outcomes upfront.
