procesdiagrams

Procesdiagrams, often referred to as process diagrams, are graphical representations of the steps, decisions, and flows that constitute a process. They visualize the sequence of activities, inputs and outputs, roles, and dependencies, helping clarify how a process functions and how it can be improved. They can range from simple task sequences to comprehensive models that map cross-organizational workflows.

Common types include flowcharts, which use standardized shapes to depict steps and decision points; data flow diagrams (DFDs), which emphasize the movement of information between processes, data stores, and external entities; business process model and notation (BPMN), a detailed standard for modeling complex processes; swimlane diagrams, which allocate activities to participating actors or units; and UML activity diagrams, used in software and systems engineering to model behavior.

Key conventions often appear across diagrams. Arrows indicate the direction of flow, rectangles represent process steps, diamonds denote decisions, and ovals mark start and end points. BPMN adds elements such as events, gateways, and lanes to show structure and responsibilities. The choice of notation depends on purpose, audience, and required detail.

Applications span many domains, including business process improvement (Lean, Six Sigma), software design, manufacturing, service delivery, and healthcare. Process diagrams support documentation, training, compliance, risk assessment, and communication among stakeholders.

Standards and tools vary by context. BPMN 2.0 is widely adopted for business processes, while UML and DFDs are common in software and systems analysis. Popular software tools include Visio, Lucidchart, and draw.io.
