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.
A Swimlane was first introduced to computer-based Process Modeling by IGrafx in 1993 and trademarked in 1996. It may also be referred to as a functional band (as it is in Microsoft Visio 2007) and is used in the same way, to create a cross functional flowchart to map a process within the functional units of a business.

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.
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 ...
Version 2.0 of BPMN was released in January 2011, [1] at which point the name was amended to Business Process Model and Notation to reflect the introduction of execution semantics, which were introduced alongside the existing notational and diagramming elements.
Example of a Sankey diagram Sankey's original 1898 diagram showing energy efficiency of a steam engine. Sankey diagrams are a data visualisation technique or flow diagram that emphasizes flow/movement/change from one state to another or one time to another, [1] in which the width of the arrows is proportional to the flow rate of the depicted extensive property.
