This RACI Chart PMP is a type of responsibility assignment matrix (RAM) in project management. In practice, it's a simple spreadsheet or table that lists all project stakeholders and their level of involvement in each task, denoted by the letters R, A, C, or I. Once these roles have been defined, assignments can be assigned, and work can begin. The task is designated as responsible when assigned directly to this person (or group of people). The person in charge is the one who completes the job or creates the deliverable. Every task should have at least one responsible person, if not more.
