This RACI Diagram has long been a favorite among project managers worldwide. It's also known as the RACI matrix, and it's used to define employee roles and responsibilities for each task, milestone, and decision made throughout a project. The chart is created to promote clear communication and smooth workflow among all team members. RACI charts can help prevent that sinking feeling that comes at the end of a project when a major decision-maker arrives and complicates things with many changes because they were not consulted throughout the project.
