They were first introduced to computer-based diagramming by iGrafx. They were called Swim Lane diagrams by Geary Rummler and Alan Brache in their book Improving Performance (1990). Swimlane diagrams first appeared in the 1940s as a variation of the flow process chart called multi-column charts. Typically over 30% productivity gains are accomplished even for processes that remain manual. ![]() A 'to be' model is then created for human processes and a related systems design document developed for those that are automated. After establishing the 'as is' workflow and systems interfaces, work steps are simplified to automate processes whenever practical and transfer steps to subsequent work processes. The term functional band came after the use of swimlane and is seemingly in decline as the acceptable term as BPMN has been more widely accepted as a modeling standard.Īnother term used is "Functional Flowchart" useful for productivity improvement and systems design projects. 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. Swimlanes are used in Business Process Modeling Notation (BPMN) and Unified Modeling Language activity diagram modeling methodologies.Ī Swimlane was first introduced to computer-based Process Modeling by IGrafx in 1993 and trademarked in 1996. Many process modeling methodologies utilize the concept of swimlanes, as a mechanism to organize activities into separate visual categories in order to illustrate different functional capabilities or responsibilities (organisational roles). When used to diagram a business process that involves more than one department, swimlanes often serve to clarify not only the steps and who is responsible for each one, but also how delays, mistakes or cheating are most likely to occur. Use of standard symbols enables clear linkage to be shown between related flow charts when charting flows with complex relationships. This can be easier to read and design, since computer screens are typically wider than they are tall, which gives an improved view of the flow. Arrows between the lanes represent how information or material is passed between the sub processes.Īlternately, the flow can be rotated so that the sequence reads horizontally from left to right, with the roles involved being shown at the left edge. ![]() In the accompanying example, the vertical direction represents the sequence of events in the overall process, while the horizontal divisions depict what sub-process is performing that step. Lanes are labelled to show how the chart is organized. Parallel lines divide the chart into lanes, with one lane for each person, group or sub process. The swimlane flowchart differs from other flowcharts in that processes and decisions are grouped visually by placing them in lanes. ![]()
