What is personal operations manual?

Example: A product manager keeps forty-plus workflows organized in a personal operations manual — three variants for writing product specs (deep-analysis, rapid-draft, template-fill), four variants for running meetings (brainstorm, decision, status-update, retrospective), two for onboarding new team members, and a dozen more for recurring operational tasks. When a new situation arises, she doesn't start from scratch. She searches her library, finds the closest match, and deploys or adapts it in minutes. A colleague facing the same situation spends an hour reinventing a process she already solved six months ago.

This concept is part of Workflow Design in the How to Think curriculum.
