Half the Story
Each team is briefed separately, on the same screen, with a full-screen curtain that does not lift until the facilitator confirms everyone else is looking away. The briefs are not the same and nobody is told that. Then one question, answered together — and the argument that follows is not about judgement, it is about information, with everybody in it being perfectly reasonable. The reveal puts both briefs side by side and marks the single line each team never saw. Five looks ship with it — the activity’s own, plus a trail junction, an assembly hall, an observatory and a winter market, drawn in the file itself with no images to load.
- Problem
- Handover failures do not look like failures from the inside. Each group acts correctly on what it holds, so afterwards everyone defends themselves convincingly and nothing gets fixed — because the conversation becomes about who was being difficult rather than about who was told what.
- Who it helps
- Teams that hand work to each other — shifts, departments, projects and vendors — and anyone teaching handover, escalation, or cross-team communication.
- In training
- Read the curtain out loud and wait. Skipping that instruction is the one way to break this activity, because a single person reading the other brief over a shoulder collapses the whole thing. Let the argument run properly before revealing — the frustration is the payload. Finish on the second question rather than the first: not “when could someone have found out”, but “where in our actual work does one group hold a line the other has never seen”.
- Skills shown
- Asymmetric information design on a single shared display, curtained sequential briefing, derived difference detection so the data cannot drift, facilitation-critical interaction design.
How to edit
- Click Edit this activity in the corner.
- Lines shared by both briefs must be written identically in both — the tool finds the private lines by comparing them, so the data cannot go out of step.
- Give each side exactly one line the other does not have.
- Both private lines must be true, reasonable, and enough on their own to justify a different answer. If one is obviously weightier, the room decides that side was right and the point is lost.
- Never announce that the briefs differ. The moment of realisation is the activity.
