The idea
Teams often blur discussion and decision. People either avoid disagreement to preserve harmony, or continue arguing after a choice should be settled. A disciplined debate separates the two phases.
Before the decision, invite competing views and make them examine the same question. Surface assumptions, request evidence, and ensure quiet experts have room to contribute. Afterward, name the decision, its owner, and what would justify reopening it. Candor belongs before commitment; clarity belongs after it.
Make it concrete
A team must choose between buying a service and building one. Before meeting, the leader frames three criteria: delivery time, three-year cost, and operational risk. Two groups develop the strongest case for each option, then switch sides and challenge their own argument. The leader decides, records the reasoning, and assigns the next action. Debate improves the choice without turning execution into an endless referendum.
Attack ideas, not status
A debate stops producing intelligence when people must defend their identity. Ask participants to critique assumptions and consequences, not competence or motives. A leader can model this by making their own preferred option examinable—and by changing their mind when the evidence warrants it.
Try it
For an upcoming decision, write one neutral question, two credible alternatives, and three shared criteria. Decide in advance who will make the final call.
