BPMNmodeling

BPMN modeling refers to the creation of diagrams that describe the steps and decisions involved in business processes using the BPMN standard. BPMN, or Business Process Model and Notation, provides a graphical language intended to be understandable by business users and technical developers alike, enabling clear communication across organizational roles. The standard is maintained by the Object Management Group (OMG), with BPMN 2.0 as the dominant version widely used since its release in 2011.

A BPMN model is built from flow objects (events, activities, gateways), connecting objects (sequence flows, message flows, associations), swimlanes (pools and lanes) to organize participants, and artifacts (data objects, groups, annotations) to add supplementary information.

Models are used to document current processes, design new ones, analyze bottlenecks, and align business requirements with IT systems. They can be exported, shared, and sometimes executed by BPMN-compatible process engines, especially when the model is expressed in executable form with appropriate data, rules, and timers. BPMN 2.0 also defines an XML interchange format and a diagram interchange to enable tool interoperability.

Benefits and limitations: The main advantage is a standardized, neutral notation that improves communication, collaboration, and interoperability between tools. Limitations include the potential complexity for large processes, the learning curve, and the fact that not all BPMN diagrams are executable or directly translatable to code; additional mapping or customization may be required.

History and scope: BPMN 2.0 unified earlier notations (e.g., BPMN 1.x, BPMN-OMG). It supports collaboration diagrams, which show interactions between participants. Tools range from Visio and Lucidchart to dedicated platforms like Signavio, Camunda, Bizagi, and IBM BPM.
