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.

90 minutes, remote. Serves 8 to 12.

How to run it

  1. Check-in

    10 min

    Say what the room will leave with and show the three steps on the board. Then ask: "In one sentence: what do you need from the next ninety minutes? Type it in the chat, but don't press Enter until I say go." Say "Go" and read the chat out loud in one pass. It's faster than a round, and nobody answers in the shadow of the person before them.

  2. Crazy 8s

    20 min

    Rounds: two rounds of eight

    Ask everyone to fold a sheet of paper into eight boxes and grab a thick pen. Read the challenge out, then: "Eight ideas, one per box, a minute each. Stick figures are fine; words are fine. No erasing." Run two rounds of eight, calling each minute out loud. When the drawing stops, everyone circles their strongest box, photographs the sheet and drops the photo into their own space in the Sketches frame. Then everyone reads the frame in silence. Nobody presents their sheet.

    In the 90 also: The second round of eight is eight versions of one idea: everyone picks their favourite box from the first round and pushes it eight ways before circling the strongest. The second round is where the ideas get specific.

    Board: Frame 1, "Sketches": one named space per person for a photo of their sheet.

  3. Heat Map Vote

    20 min

    Ideas kept for scoring: the five hottest

    Give everyone fifteen voting stamps, or fifteen small dot stickers if your board has no stamp. "Put a stamp on any part of any sketch that you'd want to see built: a whole idea, a corner of one, a single detail. As many as you like on one sketch, your own included. No chat." When the stamps stop moving, zoom out and look at where they've clustered. Then pick the five hottest by the stamps, and copy each into the Shortlist frame as one line.

    In the 90 also: Before the shortlist is picked, three volunteers each say which spot surprised them and why. One sentence each.

    Board: Uses the Sketches frame. Frame 2, "Shortlist": one line per idea going forward.

  4. NUF Test

    25 min

    Talk after scoring: the top three and the most split score

    Put the shortlist into a table on the board: a column for each idea, split into New, Useful and Feasible, a row for each person, and a Total row. "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 types their scores into their own row before anyone speaks. Total each idea and sort. Then talk through the top three and the most split score, out loud or in the chat, asking, "What would make this one more feasible?" The room leaves with one idea to build.

    Board: Frame 3, "NUF": a column for each shortlisted idea, split into New, Useful and Feasible, a row for each person, and a Total row.

  5. Commit: who does what by when

    15 min

    Each result the room produced needs an owner. Owners type "I will [what] by [when]" into the Commitments frame, under the result they own. Read every commitment back out loud. If a result has no owner, say so: "Nobody owns this yet." Type that into the frame too, so it leaves the room as an open item rather than a quiet gap.

    In the 90 also: Ask each owner one question: "What could stop this?" One sentence back. If the answer is another person, that person is in the commitment too.

    Board: Frame "Commitments": one column per result, with space for "I will [what] by [when]".
