With the help of the RACI Matrix, also known as the RACI Chart, key roles and responsibilities related to processes or individual tasks can be mapped transparently and systematically in project management. The acronym consists of four possible roles. “Responsible” refers to the person responsible for carrying out a task, who receives instructions from the person legally accountable; this person is “Accountable” for a specific process step. Experts who should be consulted for advice on important decisions are listed under “Consulted.” Those in the “Informed” category simply need to be kept updated, such as when changes occur.
