The project manager should update the change management plan to clarify the scope and process of change control for the project. The change management plan is a component of the project management plan that defines how changes will be monitored and controlled. It also specifies the level of authority needed to approve different types of changes. The project manager should ensure that the change management plan is aligned with the project scope statement and the contract terms and conditions. The project manager should not report the violation to the CCB, as this may escalate the issue unnecessarily and damage the relationship with the contractor. The project manager should not ask the quality control team to evaluate the modifications, as this may imply acceptance of the changes without proper authorization. The project manager should not request the engineering team to update the specifications, as this may create confusion and inconsistency in the project documentation. References:

According to the PMBOK Guide, the project manager is responsible for managing the project team and resolving any conflicts that may arise among team members. The project manager should use appropriate conflict resolution techniques, such as problem-solving, compromising, or collaborating, to identify the root causes of the issues and guide the team members toward a mutually acceptable solution. Removing one of the team members, warning them about their behavior, or training them on communication techniques and interpersonal behavior are not effective ways of handling this situation, as they do not address the underlying problems or foster a positive team environment.

The Project Management Professional (PMP) certification recognizes the ability of project managers to lead projects in any industry1. One of the key skills validated by the PMP certification is the ability to motivate people and teams through all phases of a successful project1. In the context of a self-organizing team, the role of the project manager as a servant leader is not to provide solutions, but to empower the team to solve problems independently. This approach fosters a sense of ownership, encourages learning, and promotes the development of problem-solving skills within the team. References: PMP Certification

One of the primary responsibilities of the Scrum Master is to remove impediments that may block the team from achieving its sprint or iteration goal. If a dependency is discovered late in the project, swift and direct collaboration is required to ensure delivery continuity. Initiating communication with the dependent team aligns with the Scrum Master's role as a servant leader and facilitator.
According to the Agile Practice Guide (Chapter 3 - Agile Roles), the Scrum Master works across teams and organizational boundaries to resolve external dependencies that may block the team. It is not the sole responsibility of the Product Owner or individual team members to manage these external issues.
Option A shifts responsibility inappropriately to the Product Owner.
Option B doesn't resolve the dependency but merely postpones or reorders work.
Option D fails to address the systemic coordination needed; it may be helpful later but isn't the primary step.

In situations where team members disagree, it is essential for the project manager to facilitate a resolution that leads to the best team performance. This involves understanding the perspectives of each team member, fostering a collaborative environment, and guiding the team towards a solution that aligns with the project's goals. The project manager should employ conflict resolution techniques such as problem-solving and collaboration, which are recommended by the PMBOK Guide. These techniques encourage open communication, ensure that all voices are heard, and work towards a consensus that supports the project's objectives and enhances team performance.
(Based on the conflict resolution strategies outlined in the PMBOK Guide and other PMP resources12.)
