How this method works
A planning method for acting out the first 20 minutes after a provisional decision, role by role. Use it when nobody knows who will communicate a decision, work stops at handoffs between responsible people, or the decision statement does not reveal the implementation sequence. Participants assign the roles that act immediately after the decision and say aloud what they receive, what they pass on, and when they stop. Moments when nobody can name the next role are returned to undecided status, preventing a plausible-looking plan from ending on paper alone. The result is a handoff script showing the initial sequence, responsible people, items transferred, and stopping conditions. Do not use it when the decision itself is unresolved and options still need comparing.
Phase schedule
Minutes are cumulative from the start of the base plan, not a live timer. Read scaling for any additional time. Phase controls do not advance automatically.

- Place the decision0–5 minutes from the start (5 minutes)
Action: Place. Participation: Everyone.
Recording not separately specified for this phase
- Assign roles5–12 minutes from the start (7 minutes)
Action: Assign. Participation: Groups of 3–5.
Individual record
- Act out the first actions12–27 minutes from the start (15 minutes)
Action: Rehearse. Participation: Groups of 3–5.
Shared record
- Fill the gaps27–37 minutes from the start (10 minutes)
Action: Fill. Participation: Groups of 3–5.
Shared record
- Choose a handoff37–45 minutes from the start (8 minutes)
Action: Choose. Participation: Everyone.
Shared record
Facilitation steps
- For 5 minutes, display the provisional decision in one sentence and identify just one role that receives the output immediately afterwards.
- For 7 minutes, each group chooses up to 4 roles that act immediately after the decision and writes what each receives on the role cards.
- For 15 minutes, simulate the first 20 minutes by acting out one action at a time in role order and arranging the handoff cards.
- For 10 minutes, return points where nobody can name the next responsible person to undecided status. Write one necessary responsible person and one transfer item for each.
- For 8 minutes, everyone reads the initial handoff script and chooses one handoff to try first and one person to check it.
If something changes
If
Three minutes into the rehearsal, the first role still cannot say what they pass on.
Then
Using the decision statement, write one sentence, document, or confirmation mark that the recipient needs on a handoff card.
If
During the rehearsal, handoffs return to the same role 3 or more times.
Then
Place one checking role before that role and record the reason for returning as a stopping condition.
If
After filling the gaps, each group still has 3 or more undecided markers.
Then
Keep only markers essential for the next 20 minutes and move later markers to the next planning area.
Preparation
Materials
- One role card per person, with a field for the responsible person’s name
- 8 handoff cards per group, approximately A6 size
- One dark-coloured pen per person
- One display sheet per group for arranging the first actions in order, approximately A2 size
Room and setup
- One island table per group of 3–5, where roles can be seen together; 1–4 tables within the supported participant range
- One table or wall surface per group where handoff cards can be placed chronologically
Adjust for people and time
With fewer than 4 people, there are fewer role handoffs, so one person takes 2 roles and replays the first actions. With 4–20, divide participants evenly into 1–4 groups of 3–5 and work on one decision. Above 20, form groups of 3–5. Each group shares one first handoff and one largest gap. Together, merge only gaps concentrated on the same role into a single script.
Safety and non-applicable situations
Keep the provisional decision distinct from undecided handoffs. Do not use the rehearsal to replace an unfinished comparison of decision options. Record stopping conditions and return missing next-role assignments to undecided status.
