In situations of conflict, it is important for the project manager to address the issue constructively. Cultivating self-awareness through emotional intelligence (EI) can help team members understand their own emotions and those of others, which is crucial in resolving conflicts. This approach aligns with the PMBOK guide's recommendations on conflict management, which suggest that problem-solving and collaboration are effective strategies for dealing with team conflicts12. By fostering EI, the project manager can facilitate a more harmonious work environment and mitigate the negative impact on the project.

According to the PMBOK Guide, one of the agile metrics that measures the quality of the team's output is the Escaped Defect Rate, which tracks the number of problems found in the product after it has been released to the customer. The lower the defect rate, the higher the quality of the product and the customer satisfaction.
Therefore, the team with the least amount of defects in their deliverables is performing better than the other teams, regardless of the number of story points they have calculated or completed. Story points are relative estimates of the size and complexity of the work, and they may vary from team to team depending on their experience, skills, and definition of done. Comparing story points across teams is not a valid way of measuring their performance, as it does not reflect the actual value delivered to the customer or the business. References:

According to the PMBOK Guide, the project scope is the work that needs to be accomplished to deliver a product, service, or result with the specified features and functions1. The project scope statement defines the project scope and documents the project deliverables, acceptance criteria, assumptions, and constraints2. The project manager is responsible for ensuring that the project scope is managed and controlled throughout the project life cycle3. If the contractor submits an offer for additional work that is already included in the initial project scope, the project manager should refuse the offer as it is not a valid change request and does not add any value to the project. The project manager should also communicate with the contractor to clarify the project scope and avoid any misunderstandings or conflicts. References:
