The team always needs to help you document the lessons learned for the project. This question isn't hard if you remember one really important fact: you need your team's help when you're writing the lessons learned. That's why you can't release the team until the lessons learned are documented and added to the organizational process assets. Also, the last thing you do on the project is close the contract. The reason for this is that you don't want to have to wait for payment before releasing the team, because most contracts have payment terms that allow for some period of time before full payment is required.

The agile leader should develop working agreements with the team to address the trouble and disputes they are facing. Working agreements are a set of guidelines or norms that the team agrees to follow to improve their collaboration, communication, and performance. They help to establish a shared understanding of the team's values, expectations, and behaviors. They also help to resolve conflicts, clarify roles and responsibilities, and foster trust and respect among the team members. Developing working agreements with the team is a participatory and iterative process that involves the input and feedback of all team members. The agile leader should facilitate this process and ensure that the working agreements are aligned with the agile principles and practices. Escalating the issue to the team's manager (option A) is not a good option, as it may undermine the team's autonomy and empowerment. Removing some of the team members (option B) is also not a good option, as it may disrupt the team's dynamics and morale. Reviewing the roles and responsibilities document (option C) is a useful step, but it may not be sufficient or effective to address the root causes of the trouble and disputes. References:
