Why: This would allow variable team capacity per month/week etc. With current state of capacity setting, teams cannot account for changes in resources for partial project spans, member additions, losses, changes etc. This makes this feature less valuable since our teams change capacity frequently.
Optional solution: Make capacity follow same logic as Demand i.e. Estimates. using scenarios. Capacity could use the same predefined scenarios e.g. "Hours/Team/Month or quarter" that Demand uses to remain consistent. This would align Estimates and Capacity in structure and format.
You can now schedule team changes to more accurately visualize team workload on the capacity report in Aha! Roadmaps — increasing your confidence that the team will be able to deliver on time.
