![]() In order to also describe external participants, you should use the collaboration. ![]() These decisions depend on whether or not you want to add a responsibility aspect to your process.Įxample of a process, with the use of lanesĪ process diagram using lanes describes participants of the process from an internal perspective only. The use of lanes, as well as the number of lanes to be used, is up to you. The name of a lane is often the name of the entity that executes the process described in that lane, although in some situations it is more useful to use the name of the process. ![]() A participant can represent the role of a person, but also systems or departments. In this way, a lane can represent roles or organizational units that perform the activities in the process, or in other words, the participants of a process. ![]() In order to describe who is involved in the execution of a process, lanes can be used. Moreover, you can add splits, joins, and repetitions of (parts of) the process with the use of gateways. In the process model, relationships ( sequence flows) are used to determine the order between the starting point, the activities, the intermediate events, and the endpoint. An activity can be broken down into underlying, lower level (more detailed) activities and in this way describe a sub-process ( sub-process, transaction, call activity). In between events, activities ( tasks) are positioned. Events determine the course of the process flow and are usually the result of a cause ( trigger), or exert some influence ( result). Events are defined as something happening during the execution of a process. However, it does not show exactly how an activity is executed, and neither where nor why the activity should be executed.Ī process runs from a starting point ( start event) to an endpoint ( end event), with the possible occurrence of events between the start and end of the process ( intermediate events and boundary events). The process diagram shows the order in which activities are organized, when and under what conditions activities should be executed, including exceptions. You model the behavior of a single process. ![]() A process diagram is used to describe the collection of activities on the path from a request for a product or service from a customer, and the delivery of that product or service to that customer. ![]()
