A delivery date can move when new requirements, defects, or dependencies appear. The most useful update comes when the new information is known, not after the original date has already passed.
Share the change and its impact
- State the original expectation and what new information changed it.
- Describe the current range or next checkpoint, including the assumptions behind it.
- Offer options such as reducing scope, changing sequence, or moving the date.
Avoid turning uncertainty into blame
Focus on the work and the decision needed. If a dependency is outside the team's control, name the dependency and the action being taken rather than assigning motive to another person.
Update the shared plan and notify the people whose work depends on the date. A clear revision helps teams make choices while there is still room to adjust.
