According to the PMBOK® Guide, specifically within the Human Resource Management (now Resource Management) knowledge area, the Plan Human Resource Management (or Develop Human Resource Plan) process involves identifying and documenting project roles, responsibilities, required skills, reporting relationships, and creating a staffing management plan.

To perform this planning process, the following are standard inputs:

Project Management Plan: Specifically the activity resource requirements and the project schedule.

Enterprise Environmental Factors (EEFs): This is a critical input that includes organizational culture and structure, existing human resources (skills and availability), personnel administration policies, and marketplace conditions.

Organizational Process Assets (OPAs): Includes templates, lessons learned, and historical information.

Analysis of Other Options:

A. Team performance assessment: This is an output of the Develop Project Team process, used to evaluate the effectiveness of the team.

B. Roles and responsibilities: This is an output (specifically a part of the Human Resource Management Plan) produced during this process, not an input to start it.

C. Staffing management plan: This is a key component and output of the Human Resource Management Plan, describing when and how human resource requirements will be met.
