In Sprint 1 you have set of features (A) e.g. 10 assigned to Team Y. Total 100 for all teams.
In Sprint 2 you have another set of features (B) e.g. 15 assigned to Team Y. Total 100 for all teams
Sprint 1 and Sprint 2 features overlap (3) for Team Y
Team Y has let’s say 500 features in the backlog. There are let’s say 10 teams (not really relevant)
What will happen when you have filter configuration:
ALL: Sprint = 1; Sprint = 2; Team Y: Only overlapped A / B / Team Z = sub-set of features in both sprint 1 and 2 for the team = 3 features
Is any of: Sprint = 1; Sprint = 2; Team Y: All features in Sprint 1 (all teams, 100) + all features in Sprint 2 (all teams, 100) + all features in Team Y is the result of this query (500).
