How do I practice role definition?

The most direct way to practice role definition is through a focused exercise: Pick a project or recurring meeting where responsibilities feel blurry. List every person involved. For each person, write one sentence that completes: '[Name] is the _ for _.' Use specific role types — owner, reviewer, advisor, executor, approver — not vague words like 'involved' or 'helping.' If you cannot write that sentence for someone, you have found the ambiguity that is costing your team.

Common pitfall: Assigning role types once and treating them as permanent fixtures rather than context-dependent labels. Roles are relational and situational — someone who is the decision-maker for architecture may be merely informed on hiring. The failure is freezing roles into identity rather than treating them as active, revisable classifications.

This practice connects to Phase 12 (Classification and Typing) — building it as a repeatable habit compounds over time.
