Map each unit to one receiver
The synthetic task contains eight cards. Mei accepts cards C01–C05 and Jo C06–C08. Ren retains final assembly after both subsets complete. The supplied process allows independent card editing; approval of the final assembled set remains a separate task.
| Scope | Owner | Units / state |
|---|---|---|
| C01–C05 | Mei | 5 / accepted work |
| C06–C08 | Jo | 3 / accepted work |
| Final assembly | Ren | Waits for all 8 |
Check coverage and overlap before closing the handover
- List all eight identities
- Assign disjoint subsets
- Record both acceptances
- Check all eight covered once
- Retain Ren’s assembly task
If both receivers claim C05 or neither accepts C06, resolve the assignment before treating the handover as complete.
Five plus three covers eight with no duplicate unit. Neither receiver alone owns final assembly. Keep the parent task and subset identities linked so progress can be joined without creating extra cards.
Mei finishes five and Jo finishes two. How many cards remain, and can Ren assemble the final set?
Show the worked answer
One card remains. Ren must wait for Jo’s third card before the complete eight-card assembly.
