BPMN
Diagram
(Business Process Model and Notation)
Description
10.35 Process Modelling (One of the models)
Used across both business and information technology domains; is increasingly adopted as an industry standard.
A key feature of BPMN is its ability to distinguish the activities of different participants in a process with pools and swimlanes.
Model categories: Activity Flow
**Four
groups of shapes**
1- Flow objects
Task:
a specific activity or work that need to be performed as part of the process (Manual; User; Service or Automated)
Sub-process
: smaller process within the main process; can be reused by other processes
Event:
something that happens during the process:
start,
intermediate,
end of a task
Gateway
: a decision point in the process where different paths can be taken
Exclusive [XOR] [EITHER OR] -default -
One path Y/N
Inclusive [OR] -
at least one path from multiple paths
Parallel [AND] - *Tasks go in Parallel. All paths completed to go on"
Complex - Specify logic for path
Event-Based Waiting for event happened (Exclusive Event-Based/ Inclusive Event-Based/ Parallel Event-Based )
2 - Connecting Objects
Sequence Flow:
represents the order in which activities, events, and gateways are connected and executed.
Message Flow:
Represents the flow of messages between pools or participants in different pools.
Association:
Represents a relationship between a flow object and a data object or text annotation.
3- Swimlanes
Who is doing what?
Pool:
Represents a major participant or external entity that encapsulates a complete process
Lane:
Represents a subdivision within a pool and defines the
roles or departments
responsible for specific activities
Artifacts:
Data Object Reference
: Refers to a specific data object that is used or produced by a task or event (Input -placed in the process; Output - from the process ;Collection - data need to be collected)
Data Store Reference:
Represents a data store that holds data used in the process
Group:
Represents a grouping of related activities or objects in the diagram - logical groupping
Text Annotation:
Provides additional explanatory information about a particular element.
