@Chip_Unicorn @polotek IMO, the developer/team need to communicate those impacts. In concrete terms: This production issue pushes out the estimates 1 week. And it’s the lead/manager’s job to do something with that info. Useful context for the manager.
The team should also reforecast at regular intervals. Ideally w/ confidence levels. Few people like surprises, and providing those estimates/forecasts keeps everyone’s eyes wide open. The resyncing process matters.
