Process Modelling Shape Guide (Enhanced Elements)
Untrained users are not expected to draw models with the enhanced elements, although they may be required to understand them.
Task
Used to describe the process activity using 'verb noun' notation. For example, lock workstation, validate application, review document, enter student details, update record etc.
Sub Process Activity
Used to indicate that there is activity delivered by a Sub Process.
Tip: the Sub Process should be referenced using an Annotation Box.
Decision
Used to illustrate the change of flow following a decision task. Tip: use a response which best suits the task prior to the decision diamond, for example pass / fail, valid / invalid, approved / not approved, UK / Non-UK etc. Tip: ensure each condition has a guard [ ].
Merge
Signifies the join of two or more flows. This may be as a result of corrective action where once an item has been corrected it needs to merge back with the main flow.
Fork and Join
Used to illustrate the beginning (fork) and end (join) of parallel activity (usually carried out by two or more actors) in the process. Tip: If the parallel activity does not re-join then the Flow Final indicators must be used to signify the end of the process.
Final Flow
Used to end one stream of a parallel flow where the rest of the process is continuing. Tip: there will always be more than one flow final. Tip: if flow finals are present then the Target Shape should not be used.
Time Event
Can be used to signify a time based trigger, for example "7am" at the start of a flow, or waiting time within a flow, for example "1 hour".
