This answer is based on the best practice of conflict resolution in project management, which is to use a collaborative or problem-solving approach that seeks a win-win outcome for all parties involved12. By facilitating a meeting, the project manager can help the team members communicate effectively, understand each other's perspectives, and find a mutually acceptable solution that meets the project requirements. This way, the project manager can also maintain team morale and cohesion, and avoid imposing a decision that may cause resentment or dissatisfaction among the team members3.

A wiki knowledge base is a tool that allows the project team to store, organize, and share information that is
captured throughout the life cycle of a project. A wiki knowledge base is stored in a centralized location that is
easily accessible to all stakeholders via a web browser. A wiki knowledge base also provides search
functionality that enables the users to find the information they need quickly and easily. A wiki knowledge
base can help the project team to document the project requirements, scope, schedule, budget, quality, risks,
issues, lessons learned, and best practices.
A wiki knowledge base is different from a secure folder, which is a tool that protects the files and folders from
unauthorized access or modification. A secure folder may not be easily accessible to all stakeholders, and may
not provide search functionality or collaboration features. A wiki knowledge base is also different from a
real-time, multiauthoring editing software, which is a tool that allows the project team to create and edit
documents simultaneously and synchronously. A real-time, multiauthoring editing software may not be
suitable for storing large amounts of information, and may not provide the same level of organization and
structure as a wiki knowledge base. A wiki knowledge base is also different from a digital whiteboard, which
is a tool that allows the project team to brainstorm, visualize, and communicate ideas. A digital whiteboard is
not designed for storing information, and may not provide the same level of search functionality or security as
a wiki knowledge base. References = CompTIA Project+ Study Guide: Exam PK0-005, 3rd Edition, Chapter

A self-organized team is a typical characteristic of Scrum, which is an agile framework for managing complex projects. A self-organized team is a group of motivated and skilled individuals who have the autonomy and authority to make decisions and collaborate on how to deliver the project goals. A self-organized team does not rely on a manager or a leader to assign tasks, monitor progress, or resolve issues. Instead, a self-organized team uses Scrum events, such as daily stand-ups, sprint planning, sprint review, and sprint retrospective, to coordinate their work, communicate with each other, and inspect and adapt their process and product123.

Submit a change request to the change control board. The project manager should submit a change request to the change control board (CCB) if they realize that the project will not be completed on time due to resource constraints. A change request is a formal proposal to modify any aspect of the project, such as scope, schedule, cost, quality, or resources. A change request must be submitted to the CCB, which is a group of stakeholders who are authorized to review and approve changes. Submitting a change request can help to document the impact of the resource constraints on the project and seek approval for any corrective actions or preventive actions12

This answer is based on the best practice of stakeholder management, which is to identify and document the communication preferences of each stakeholder or stakeholder group12. The project manager should update the stakeholder register with the information gathered from the stakeholder analysis, which includes the preferred communication channel for each stakeholder3. The preferred reported communication channel reflects the majority preference of the stakeholders, as well as the minority preference of the face-to-face communicators. The project manager should use this information to plan and execute effective communication throughout the project life cycle4.
