It helps decompose these processes and collects information about current operations. A workflow system design is a set of specifications describing the new system. Process reengineering involves the activity of analyzing a workflow system to improve throughput and find productivity gains. Both require a detailed knowledge of the business environment, including goals, objectives and environmental characteristics. When performed simultaneously with workflow system design, process reengineering changes current methods in response to the proposed new environment.
Process reengineering implies that some amount of engineering has already taken place.
However, it can be performed regardless of whether the methods have been engineered or are the result of evolution. Interest in workflow systems is directly related to the availability of imaging technology. Previously, computer systems could not adequately address operations involving paper-based information. Because imaging can deliver such information to the workstation, use of other labor-saving programs becomes practical. Decreased cost and increased performance result from determining the appropriate programs, and how they are used.
