Why do Agile teams use iteration goals?

Agile teams utilize iteration goals primarily to align team members and the Product Owner to a common purpose. The iteration goal provides a clear focus for the team during each iteration, ensuring that everyone understands the objectives and priorities for that specific time frame. This alignment fosters collaboration and ensures that the team's efforts are directed towards delivering value that is consistent with stakeholder expectations.

Having a shared goal helps in maintaining motivation and enhances communication among team members, as they work collectively towards achieving that objective. By focusing on a common purpose, the team can better respond to changes and adapt as needed while remaining aligned on what they aim to accomplish in that iteration.

In contrast to the other options, which may pertain to specific metrics or aspects of team performance, the core purpose of iteration goals is about creating unity and a shared direction within the team, making option B the most suitable choice.
