The term human resource planning refers specifically to a project management process that involves the careful and deliberate identification, categorization, and ultimately, documentation of the entirety of all project roles assigned to all individual members of the project work team. Included among this documentation process is a careful delineation of all of the individual project team members‘ personal responsibilities in regards to management of the project, as well as all the specific reporting relationships among all members of the project team. One additional essential component of the project management process of human resource planning is a careful and thoroughly executed encapsulation of all members of the project team through a complete project staffing management plan. This can be done through the use of either a formally written document, which can include a detailed graphically formatted chart, or it can be in the form of a less formalized document of sorts.
This term is defined in the 3rd and the 4th edition of the PMBOK.
