In multi team agile settings it is important to ensure that the product increments coming from the teams, integrate successfully to create business value.

Done is all done
In agile, teams tend to focus on the work coming from the backlog of the team. In a multi-team environment this can result in a not working solution due to integration problems. Agile teams must take full responsibility for a working solution, including integration, this requires a coordinated approach.

Integrate often
Big bang integration and ad-hoc integration must be avoided as there is little control and high risk for integration defect. Frequent integration reduces the integration risk due to the smaller integration parts..

Share knowledge
Identifying integration risks and execution of integration tests requires deep knowledge of the full business landscape. This knowledge is often scattered over teams and/or centralized in only a few people. Knowledge sharing between teams is essential to ensure that all teams have sufficient knowledge of the full landscape so they can do their share of integration testing.
