Responsible, accountable, consult and inform (RACI) is an example of which of the following?

According to the PMBOK® Guide (6th Edition), the RACI chart is a common type of Responsibility Assignment Matrix (RAM). A RAM uses a matrix format to show the relationship between work packages (or activities) and project team members.

The RACI model is specifically designed to ensure clear division of roles and responsibilities by using the following four statuses:

Responsible: The person who performs the work.

Accountable: The person ultimately answerable for the correct and thorough completion of the deliverable or task (only one person can be accountable for each task).

Consult: The people whose opinions are sought (two-way communication).

Inform: The people who are kept up-to-date on progress (one-way communication).

Analysis of Distractors:

A (Text-oriented format): These are used for documenting team member responsibilities that require detailed descriptions. Usually in paragraph form, they provide information such as responsibilities, authority, and qualifications. A RACI is a matrix, not text-oriented.

B (Resource management plan): The RACI chart is a component or an output used to help develop the Resource Management Plan, but it is not the plan itself. The plan is the broader document describing how all resources will be acquired and managed.

C (Organization chart): This is a hierarchical graphic display of project team members and their reporting relationships (e.g., an Organizational Breakdown Structure - OBS). It shows who reports to whom, but it does not map individuals to specific work activities like a RAM/RACI does.
