The best practice in project management, as per the PMP objectives, is to mitigate risks associated with resource availability by facilitating cross-functional knowledge transfer. This ensures that multiple team members are skilled in various components of the project, which allows for continuity of work in the event of an absence. The PMBOK Guide emphasizes the importance of knowledge transfer to enhance the team's ability to manage project risks and maintain productivity1.
