Use offsets from the agreed delivery event
Synthetic order O-188 completes on 30 October. Data approval is due four calendar days before completion; preparation is due two days before. Moving completion to 2 November gives new due dates of 29 and 31 October. Already completed tasks keep their actual dates. Any unfinished prerequisite without an owner prevents schedule confirmation, even if the customer-facing completion date has been changed.
| Task | Offset | Original due | New due |
|---|---|---|---|
| Data approval | Completion minus 4 days | 26 October | 29 October |
| Preparation | Completion minus 2 days | 28 October | 31 October |
| Completion | Anchor event | 30 October | 2 November |

Does moving completion three days later move each unfinished offset task by three days?
Show the worked answer
Yes under this fixed calendar-offset fixture: 26 to 29 October and 28 to 31 October. Feasibility still needs review.
The offsets are synthetic scheduling rules. This differs from booking capacity and does not reserve staff or resources.
