A process review is a regular, thorough check of an implemented business process and its instances. Typically it’s done by the process owner, chief process officer, process consultant or by a manager of the reviewed process. You can simply see such a review as a type of necessary periodic maintenance. The goal is to make sure that a process is up to date, complete and being properly executed. In practice, the process owner may, for example, do an yearly thorough check up of key business processes and the results of the review are then implemented and discussed within the team involved. However, the exact meaning of a process review will vary according to the process methodology being used. A higher level of control might be considered a process audit, whereas a lower level is more of an ongoing process evaluation.
