Usage of activities before or-splits

Revision date:

Purpose

For a clear process, an or-split requires a preceding task.

Positive samples

Negative samples

Description

This rule checks if an activity has been defined before a XOR gateway. To split the active process flow, an activity must have been performed beforehand. To comply with this rule, you have to model a task before any XOR gateway.

If this is shown as an error, you have to model an activity before a XOR gateway. The following splits are or-splits: data-based exclusive (XOR) gateway, Event-based gateway or inclusive gateway.
