Business Process Model Notation, the BPMN standard:
Provides businesses with the capability of understanding their internal business procedures in a graphical format. BPM modeling notation gives organizations the ability to communicate these procedures in a standard manner.
An activity is any work that is being performed in a process. An Activity is represented by a rounded-corner rectangle in a Business Process Model. There are two types of activities tasks and sub-processes.
Annotations can be used to add textual comments within a process diagram.
Artifacts allow process designers to extend the basic BPMN notation to include additional information about the process in the process diagram. There are three types of artifacts: data object, group, and annotation
An Association is used to show relationships between data, text and other Artifacts and flow objects in a process. An Association is represented by a dotted line with a lined arrowhead in a Business Process Model.
Business Process Diagram (BPD)
A Business Process Diagram is a simple diagram made up of a set of graphical elements that depicts a business process. There are four primary elements of BPD: flow objects, connecting objects, swimlanes, and artifacts.
Business Process Model
BPMN defines a Business Process Model as a network of graphical objects, which are activities, and the flow controls that define their order of performance.
Business Process Modeling Notation
Business Process Modeling Notation was developed by the Business Process Management Institute to provide a process modeling notation that is understood by all process modelers, users, analysts, etc.
Flow Objects are connected together using Connecting Objects. There are three types of Connecting Objects: Sequence Flow, Message Flow, and Association.
Data Objects are used to show how data is required or produced by activities in a process. Data Objects are represented by a picture of a piece of paper folded at the corner in a Business Process Model.
Events are anything that “happens” during the course of a business process. Events can have a cause, referred to as a Trigger, and/or an impact, referred to as a Result. Events are based on where they occur in the flow process (start, middle, or end).
