Business Process Model and Notation (BPMN) is a standardized graphical language for documenting, analyzing, and designing business processes using a consistent set of symbols and conventions. Developed and maintained by the Object Management Group (OMG), BPMN creates a bridge between business process design and implementation by providing notation understandable to business analysts, technical developers, and process participants.
BPMN encompasses several core element categories: flow objects (activities, events, gateways) representing process steps and decision points; connecting objects (sequence flows, message flows, associations) showing relationships between elements; swimlanes (pools, lanes) organizing activities by participants or roles; and artifacts (data objects, groups, annotations) providing additional process information. These standardized elements create a comprehensive visual language for process representation at varying levels of detail.
For technology executives, BPMN delivers strategic value by providing a common language bridging business and technical domains; enabling precise requirement specification for process automation; facilitating impact analysis for process changes; supporting simulation for performance optimization; and creating executable models for direct implementation in process engines. It transforms process documentation from ambiguous descriptions to precise models supporting both human understanding and technical implementation.
Within architecture practice, BPMN serves multiple essential functions: it provides detailed process documentation supporting capability modeling; enables process analysis identifying improvement opportunities; creates functional requirements for solution architecture; supports service identification for service-oriented architectures; and provides implementation specifications for workflow automation. This versatility makes BPMN a critical tool connecting business operations to technical solutions.
While BPMN 2.0 (released in 2011) remains the current standard, its application continues to evolve through extended implementation practices. Contemporary approaches incorporate customer journey mapping relating processes to experience design; decision modeling separating business rules from process flows; event modeling emphasizing event-driven interactions; process mining comparing modeled processes with actual execution; and low-code implementation platforms generating applications directly from models. These extensions transform BPMN from documentation notation to a comprehensive business process management framework spanning design, analysis, implementation, and optimization.
