In this topic, the core set of BPMN elements is introduced. For simple process modeling for documentation and communication purposes, the core set provide adequate means to easily create understandable diagrams. For creating more complex process models, the complete set of BPMN elements is required. For information on the complete set of elements, see BPMN Elements and its sub-topics. The full list of BPMN elements and attributes with their descriptions can be found in Business Process Modeling Notation, V2.0 (OMG Document Number: formal/2011-01-03 Standard document URL: http://www.omg.org/spec/BPMN/2.0/PDF), which has been used also as reference for this guide.

 

The basic categories of BPMN elements are:

 

Flow objects

Connecting objects

Swimlanes

Artifacts

 

Flow Objects

 

Flow objects include events, activities, and gateways.

 

Name

Description

Event

Refers to something that happens during a process. The basic event types are:

Start event: starts a process flow

Intermediate event: happens during the course of a process flow

End event: ends a process flow

pic_event_core

Activity

Functions as a generic term for the work that a company performs. The types of activities are:

Sub-process: used when the work in the process is further modeled in more detail on a lower process level

Task: used when the work in the process is not broken down to a finer level of process model detail

pic_subprocess_core
pic_task_core

Gateway

Acts as a decision point in a process flow. Internal markers will indicate the type of behaviour control, which can be, in addition to traditional decision making, forking, merging, and joining of paths.

pic_gateways_core

 

Connecting Objects

 

Connecting objects include sequence flows, message flows, and associations.

 

Name

Description

Symbol

Sequence flow

Used for showing the order in which activities will be performed in a process.

pic_sequenceflow_core

Message flow

Used for showing the flow of messages between two separate process participants (such as two pools in the diagram) that send and receive them.

pic_messageflow_core

Association

Used for showing the inputs and outputs of

activities by associating data, text, and other artifacts with flow objects.

pic_association_core

 

Swimlanes

 

Swimlanes include pools and lanes.

 

Name

Description

Symbol

Pool

Represents a participant in a process. It also acts as a graphical container for partitioning

a set of activities from other pools.

pic_pool_core

Lane

Functions as a sub-partition within a pool and extends the entire length of the pool, either vertically or horizontally. Lanes are used for

organizing and categorizing activities.

pic_lane_core

 

Artifacts

 

Artifacts include data objects, groups, and text annotations.

 

Name

Description

Symbol

Data object

Shows how data is required or produced by activities. Data objects are connected to activities through associations.

pic_dataobject_core

Group

Grouping can be used for documentation or analysis purposes. It does not affect the sequence flow.

pic_group_core

Text Annotation

Allows a modeler to provide additional text information for the reader of a BPMN diagram.
