Final answer:
The Project Management Institute defines best practices for projects, programs, and portfolios, but does not have a specific category for 'project personnel' best practices. (Option c)
Step-by-step explanation:
The Project Management Institute (PMI) is a renowned organization that sets standards and best practices in the field of project management. However, when it comes to the explicit definition of best practices for project personnel, PMI's guidelines are more broadly focused on the overall project management process rather than individual roles within the project team.
PMI primarily concentrates on providing a framework for managing projects, programs, and portfolios through its Project Management Body of Knowledge (PMBOK). This comprehensive guide outlines various knowledge areas, processes, and methodologies essential for successful project execution. While PMI emphasizes the importance of competent and skilled project personnel, it does not delve into specific best practices tailored exclusively for individual team members.
In essence, PMI's approach is to establish standardized principles that enhance organizational project management practices, ensuring consistency and effectiveness across projects. Project personnel, including project managers and team members, are expected to apply the general principles outlined in PMBOK to their specific roles. Thus, the absence of specific best practices for project personnel makes (c) Project personnel the correct answer in the context of PMI's guidelines.
