From United States military and government briefing practice; the term is Pentagon usage, and NASA credits Hans Mark with building it out of the tiger team.
Puts a single brief, estimate, or plan in front of a panel chosen to question it hard, so every weak point surfaces in rehearsal before the real audience sees it.
When to reach for it
Before a briefing, board paper, or testimony goes to an audience that will probe it, when its authors have only reviewed it themselves.
How it runs
- Recruit three to six skeptical reviewers new to the work.
- Brief them on the product.
- Let them question every assumption, source, and conclusion under time pressure.
- Note each weak point the authors did not anticipate.
- Revise, and repeat with a fresh panel if needed.
