Decide

Choose the idea to build

Go from a room full of half-formed ideas to the one you'll prototype next. Ideas are judged on whether they're new, useful and doable, not on who sketched them.

60 minutes, in person. Serves 8 to 12.

How to run it

  1. Check-in

    5 min

    Say what the room will leave with. Then ask: "One word for how you're arriving." Take the words in any order, not round the circle.

  2. Crazy 8s

    15 min

    Rounds: one round of eight

    Hand everyone a sheet folded into eight boxes and a thick marker. Read the challenge out, then: "Eight ideas, one per box, a minute each. Stick figures are fine; words are fine. No erasing." Run one round of eight, calling each minute out loud. When the drawing stops, everyone circles their strongest box and tapes the whole sheet to the wall. Then the room walks the wall in silence. Nobody presents their sheet.

  3. Heat Map Vote

    10 min

    Ideas kept for scoring: the three hottest

    Give everyone fifteen small dots. "Put a dot on any part of any sketch that you'd want to see built: a whole idea, a corner of one, a single detail. Put as many as you like on one sketch, your own included. No talking." When the dots stop moving, step back and look at where they've clustered. Then pick the three hottest by the dots: those ideas go forward. If one sketch has two hot spots, take each as its own idea.

  4. NUF Test

    20 min

    Talk after scoring: the top two

    Put the shortlist on the wall as rows, with three columns: New, Useful, Feasible. "Give each idea a gut score out of seven on all three. New: unlike what's been tried. Useful: it fixes the problem without making another. Feasible: we could do it with the people, time and money we have." Everyone scores alone on a card before anyone speaks; a leader who calls out first pulls every score toward theirs. Add the cards up and sort by total. Then talk through the top two, asking, "What would make this one more feasible?" The room leaves with one idea to build.

  5. Commit: who does what by when

    10 min

    Each result the room produced needs an owner. The owner writes "I will [what] by [when]" on a card, reads it out and sticks it under the result. Only owners speak. If a result has no owner, say so: "Nobody owns this yet." Write that on the wall too, so it leaves the room as an open item rather than a quiet gap.
