According to the PMBOK Guide, 7th edition, section 5.3.2, in an agile product development environment, the project manager should facilitate communication and collaboration among the teams, especially when they are geographically dispersed. The project manager should also ensure that the teams follow a relay pattern of handing off work from one team to the other, which means that each team completes its work and passes it on to the next team in a timely and efficient manner. This way, the teams can deliver the sprints with high quality and customer satisfaction. The project manager should not isolate the teams, ignore the communication issues, or avoid the risks, as these actions would jeopardize the success of the project. References:
