Three teams are working on the same feature. Team A is complicated subsystem team, and team B and C are stream-aligned teams. During PI planning, Teams B & C commit to delivering by the end of iteration five. They plan to integrate with each other and with team A's piece in the first week of the IP iteration. Why is this an anti-pattern?

1)- Because work should not be planned for the IP iteration

2)- Because the teams managed their dependencies and planned their integration timing during PI planning

3)- Because Product Management accepted each team's final plan at the end of PI Planning Day 2

4)- Because each feature team needs to integrate with the component team
