what is business process modeling and notation

UML includes a set of various types of diagrams with different subjects of modeling andĭiversified graphics styles. The Unified Modeling Language (UML) is a general-purpose modeling tool in the field of software engineering for constructing all types of computerized systems. We will provide an example of DFD in the Sidebar section of this chapter to illustrate the integration of data and business tasks in documenting a business process. More importantly, while describing a business process by using DFD, the data stores used in the process and generatedĭata flows in the process are also defined. The top-down approach is consistent with the system concept that views a system inĪ holistic manner and concerns an understanding of a system by examining the components and their interactions within the system. The central concept of DFD is a top-down approach to understanding a system. However, BPMN is short of the ability of system decomposition for large information systems.ĭFD has served as a foundation of many other tools of documentation of business process. The flowchart style diagrams in BPMN can provide detailed specifications business processes from start to end. The objective of BPMN is to support business process documentation by providing intuitive notations for business rules.

(BPMN), Data Flow Diagram (DFD), and the Unified Modeling Language (UML).īPMN is an extension of the traditional flowchart method by adding more diagramming elements for descriptions of business process. The most commonly used business process diagramming tools are Business Process Modeling Notation There have been many types of business process diagramming tools, and each of them has its own style and syntax to serve its particular purpose. Diagrams have been used as tools for business process modeling in the information systemsįield. Natural languages (e.g., English) are incapable to explain complex business processes. A diagramming tool for documentation of business process is a formalized visual language that provides systems analysts with the ability to describe the business processes unambiguously, to visualize the business processes for systematic understanding,Īnd to communicate the business process for business process management.
