It is used when observing a physical process, to record actions as they happen, and thus get an accurate description of the process. It is used when analyzing the steps in a process, to help identify and eliminate waste—thus, it is a tool for efficiency planning. It is used when the process is mostly sequential, containing few decisions.
A process flow diagram (PFD) is a diagram commonly used in chemical and process engineering to indicate the general flow of plant processes and equipment. The PFD displays the relationship between major equipment of a plant facility and does not show minor details such as piping details and designations.
Process-control-flow diagram, used in process management; Quality-control-flow diagram, used in quality control. In software and systems development, control-flow diagrams can be used in control-flow analysis, data-flow analysis, algorithm analysis, and simulation. Control and data are most applicable for real time and data-driven systems.
At a fork, the process creates one or more additional processes, indicated by a bar with one incoming path and two or more outgoing paths. At a join, two or more processes continue as a single process, indicated by a bar with several incoming paths and one outgoing path. All processes must complete before the single process continues.

Control charts are graphical plots used in production control to determine whether quality and manufacturing processes are being controlled under stable conditions. (ISO 7870-1) [1] The hourly status is arranged on the graph, and the occurrence of abnormalities is judged based on the presence of data that differs from the conventional trend or deviates from the control limit line.
In 1947, ASME adopted a symbol set derived from Gilbreth's original work as the ASME Standard for Process Charts. Business process mapping, also known as process charting, has become much more prevalent and understood in the business world in recent years. Process maps can be used in every section of life or business. The Major Steps of Process ...
The detailed process model and the global process model represent different perspectives on the same business system, so these models must be mutually consistent. [2] A macro process map represents the major processes required to deliver a product or service to the customer. These macro process maps can be further detailed in sub-diagrams.
The Business Process Management (BPM) world acknowledges the critical importance of modeling standards for optimizing and standardizing business processes. The Business Process Model and Notation (BPMN) version 2 has brought significant improvements in event and subprocess modeling, significantly enriching the capabilities for documenting ...
