Scheduling / Shared work
A shared assignment has one contribution mode for all its contributors: independent or simultaneous. The choice determines whether their working intervals must align.
Understand the model ↓See the worked example →Contributors can use different scheduled periods and requested start times. Each contribution has its own planned duration, following the stage duration unless explicitly adjusted. The stage finishes when every required contribution has finished.
Adding a second contributor does not automatically divide one estimate in half. Work that can be split into separate deliverables may be clearer as separate stages.
For a simultaneous stage, every contributor reserves the same stage duration in matching common-availability intervals. Calendars, breaks, leave, commitments and other allocated work reduce that intersection.
A one-hour review needs an hour when both Alice and Ben are free. Alice’s free morning cannot replace Ben’s missing morning. The common intervals may span more than one day if needed.
Every contributor to the underlying assignment uses the same mode. Mixed independent and simultaneous contributions are rejected. Use separate dependent stages for work that genuinely needs different arrangements.
Dependent work waits for completion of the shared stage, including all independent contributions. A small interruption can therefore delay another person’s next task by losing a common window.
