Facilitator pack = one session-ready artifact you can run now. Workspace = a saved planning thread when the work needs follow-through, shared context, or outputs to circulate.
- 0-10 min - Objective and scope: Define decision this map informs.
- 10-35 min - Assumption harvest: Generate assumptions across categories.
- 35-65 min - Impact-uncertainty mapping: Position and discuss assumptions.
- 65-90 min - Testing plan: Write test owner and due date for top assumptions.
Checklist for tomorrow
Track readiness before the session starts and before you hand off outcomes.
