The Business Process Model and Notation (BPMN) is a technique to graphically represent business processes. The different symbols map activities, documents, events and systems as well as their interrelationships. Each object class has its own graphical equivalent so that they are easily distinguishable. Responsibilities, departments or other organizational units are represented by pools and lanes. BPMN 2.0 is the standard modeling language in business process management.
The notation has established itself as a standard in the areas of business process management and all disciplines based on it, such as Process Mining. In addition, having a standard notation is important, since the corresponding processes are understandable for everyone who is familiar with BPMN. Such standards also simplify the work of analysts and vendors of tools, as there is no need to learn and implement an infinite number of modeling elements and languages. In addition, the process exchange between departments, companies and industries is facilitated. Furthermore, a uniform process representation simplifies the switch between modeling and analysis software.
The notation is used to represent processes, such as business processes. With BPMN, steps and processes are assigned certain notations and visualized accordingly.
The most important objects of the notation are:
For a complete model, at least one start and one end event and one work step, called an activity, must be defined. The sequence of the activities can be represented conditionally and with temporal classification (following, parallel). In addition, instances are defined, persons responsible or machines that carry out the activities.
