- Divide the group into multiple small teams of 3-5 people.
- Have each team draw on a wall/large-poster sheet a 4×4 grid* with column headings of R, A, I and D.
- Instruct the teams to write risks, assumptions, issues and dependencies on post-it notes and place them in the appropriate columns as fast as possible. The goal is to be the first team to have three items in any column or four in any row. The first team to do so should shout “Bingo!”
- When a team shouts Bingo, tell all teams to pause. Invite the winning team to announce and briefly describe each of their items.
- Resume play! Have the teams keep their post-it notes on the boards and continue to try to get a(nother) full column or row.
- The next team to shout Bingo must have all unique items (they cannot have the same items that the first winning team used).
- Repeat until the teams have covered most of their boards (usually by the third “Bingo”). Then do the final Bingo “coverall” — first team to cover all squares wins.
After you’ve generated many unique project concerns, unify all teams’ contributions into one board. At this point, you can discuss them in more depth or simply defer the discussion and mitigation strategy until later (but hopefully not too much later!).
