Flow objects are the graphical elements that define the behaviour of a business process. There are three Flow Objects: Events, Activities and Gateways.

 

Events

An event is something that occurs during a business process and is represented by a circle. Events affect the flow of the process and generally have a cause (trigger) and a result. There are three different types of events: start, intermediate or end, where each group has its own drop-down combo box.

 

 

To insert an Event:

1.Click the combo box to open the drop-down list of the type of event you want insert.
2.Select the specific Event and click in the diagram tab to insert it.

Start Event

event-intermed

Intermediate Event

Intermediate events can be attached to the boundary of a Task or Sub-Process, and show that the activity is to be interrupted when the event is triggered.

event-end

End Event

Activity

Activities are actions that are performed during a business process, and are represented by rounded rectangles. Process models can contain the following types of activity: Process, Sub-Process and Task. Activities can occur singly or multiple times within a loop.

bp-task

 

To insert an Activity:

1.Click the specific Task or Sub-Process icon of the icon bar.

2.Click in the diagram tab.

 

Activity - Task

Tasks are activities that are included in a process. Tasks cannot be broken down into lower level subtasks, they are atomic.

 

 

Loop Task

Multi Instance Task

Compensation Task

bp2-taskTypes

 

 

To define a Loop, Parallel, Sequential or Compensation marker:

Right click the inserted task and select the specific marker, e.g. Show | Show BPMN Parallel Marker.

bp2-marker

Note: You can also define the Marker in the Properties tab under the "MultiInstanceLoopCharacteristics entry.

 

Activity - Sub-Process

A Sub-Process is a compound activity that is included in a process, and allows hierarchical business process model development. A Sub-Process can be broken down into finer detail through various sub-activities.

 

A collapsed Sub-Process is displayed as a top-level element, where the details of the sub-process are not visible. A "plus" icon in the element shows that an additional layer of complexity exists.

 

An expanded Sub-Process displays the details of the Sub-Process within its boundaries. Note that a sequence flow cannot cross the boundary of a Sub-Process.

 

Gateway

Gateways are used to determine how Sequence Flows branch and merge within a process, and are always shown as a diamond.
