Process Elements
|
|
Start
A Start element is used at the beginning of every process or sub-process and can be linked to multiple following elements/tasks. A process can have multiple start elements.
|
|
|
Task
A task is an element for human interaction in your processes. A task has three tie points:
|
|
The control flow flows into the green entry tie point.
The control flow flows out of the orange exit tie point.
The clock icon on the right side is used for escalations where the control flow takes an alternative path, e.g., the task needs to be finished within three hours.
Note: A task does not execute until all incoming paths (green entry tie point) are completed. If a path is redirected due to a condition, then this path is deactivated, and the task no longer waits for it to execute.
|
|
Condition
Conditions are used to fork the control flow within a process. By default, a condition has two exit tie points (“true” and “false”) but can be modified to provide more than two exit tie points. You can rename the condition and all exit tie points. Exit tie points can be added and removed as needed. Conditions should be phrased like questions, e. g. "Is the document valid?".

Event
An event is usually known from the event-driven process chain (EPC) and is used to visualize a certain process state, e.g., Invoice received.
|
|
|
End
The end element is the last element in every process or sub-process. It has only one entry tie point. A process can have one or multiple end elements. An end element can be linked to multiple preceding elements/tasks.
|
|
|
Sub-Process
A sub-process is like a container, in which multiple process steps are found. This is then labeled as one single element in order to simplify the appearance of the process. Most of the time it is used for more complex processes so that not all tasks are shown but only the most important ones. This can be useful when presenting a process to an audience where some details are less important and can be put into a sub-process.
