According to the PMBOK Guide, one of the tools and techniques for managing team resources is ground rules. Ground rules are the standards of behavior that the team members agree to follow while working on the project. They can include topics such as communication, decision making, conflict resolution, meeting etiquette, and so on. Ground rules help to establish a common understanding and expectations among the team members, especially when they are geographically distributed and have different cultural backgrounds.
Developing protocols for resolving conflicts between team members is an example of setting ground rules that can help to address the development issues and improve productivity. Forcing the team members to work from one location, obtaining special expertise, or setting up face-to-face meetings are not the best options, as they may not address the root cause of the problem, may be impractical or costly, or may create more conflicts.

According to the PMBOK Guide, an iteration is a fixed time period during which a set of activities are performed to deliver a potentially releasable product increment. In an agile or hybrid environment, the project manager should encourage the team to continuously inspect and adapt their processes and practices to improve their performance and deliver value to the customer. If a team member suggests a new method of doing things that provides no value to the end customer, but may help the team to work more efficiently, the project manager should consider the change because it will help the team work more efficiently. This means that the project manager should evaluate the benefits and costs of the proposed change, and determine if it is worth implementing. The project manager should also consult with the team and the product owner to get their feedback and approval. The change should not be immediately added to the product backlog, as it may disrupt the prioritization and planning of the customer requirements. The change should not be presented to the project sponsor for approval, as it is not a significant change that affects the project scope, schedule, or budget. The change should not be rejected because it adds no value to the end customer, as it may add value to the team and the project by improving the team's efficiency and quality.

According to the PMI Guide to Business Analysis, emotional intelligence is the ability to perceive, understand, and manage one's own and others' emotions. It is an essential skill for agile teams, as it helps to foster collaboration, trust, communication, and feedback. A project leader who invests in developing the team' s emotional intelligence can help to motivate the team members, resolve conflicts, and improve performance.
Asking the unmotivated team member to take a short leave, reducing the number of meetings, or sending the team member to another team are not effective solutions, as they do not address the root cause of the problem or help the team member to improve their motivation and engagement. References:
