To view team capacity, the Teams feature must be enabled.
With the Teams feature enabled, Release Capacity Planning is an activity that teams use to determine bottlenecks early and only commit to work they can successfully complete. In Lifecycle, you can get a see these bottlenecks by viewing team capacity details on the Release Scheduling page.
As teams negotiate and detail out their workload during release planning, the system shows each team's current load in relation to it's capacity. For component teams planning work across multiple projects at once, the system ensures that an accurate picture is shown by factoring in work from other projects that will eat into the team's capacity as well.
