procesmodellering

Procesmodellering is the creation of abstract representations of how work is performed within an organization. Models describe the sequence of activities, decision points, data flows, resources and constraints that constitute a process. The aim is to make processes explicit, shareable and more amenable to analysis, improvement, and automation. Process models are used to design new ways of working, assess compliance with rules, and communicate requirements to stakeholders.

Common notations include Business Process Model and Notation (BPMN) 2.0, UML activity diagrams, flowcharts and value-stream maps. A typical process model identifies elements such as activities, events, gateways (decisions), data objects, roles or pools and lanes (to indicate responsibility), as well as inputs and outputs. Models may be presented at different levels of detail, from high-level end-to-end flows to detailed task-level specifications.

Process modeling is a core activity in business process management (BPM) and enterprise architecture. It supports various stages: discovery or as-is modeling to understand current performance; redesign or to-be modeling to propose improvements; implementation and automation; and monitoring or simulation to evaluate impact. Techniques such as process mining can derive models from event logs, while simulation tools test performance under hypothetical scenarios.

Benefits include clearer governance, improved communication, faster change, and better alignment with objectives. Challenges include keeping models up to date, achieving stakeholder buy-in, balancing simplicity with accuracy, and integrating models with IT systems. Standards and tools continue to evolve, with BPMN as a predominant notation and tools ranging from lightweight diagram editors to comprehensive BPM suites.
