Responsibility is a common term in project management but it is defined as a task that can be assigned within the project management plan. The delegated resource – usually a project team member – should incur a duty to perform the requirements of the task or assignment. In other definitions, responsibility is also referred to as the assigned duties that a particular project team member is expected to do to complete the project.

Responsibility is a common concept in the Human Resource Management Plan. Without it, the project team members will not know what tasks they need to perform to complete the project. The thing is that it provides guidance to the project team so that they can direct themselves to perform tasks that are necessary for the success of the project.

It is the role of the project manager to delegate the responsibilities and tasks of every capable team members. Moreover, it is necessary for the project manager to check the quality of the tasks that responsible team members have performed. This is the reason why management responsibility is a common element of this concept.

This term is defined in the 5th edition of the PMBOK.
