Conformance issues
The conformance check distinguishes different reasons for the non-conformance of cases. These reasons are called conformance issues.
There are several types of conformance issues.
The following figure shows a schematic BPMN process. The process is the reference model for the examples of the non-conformance types described below.

A particular pair of activities occurs in the wrong order.
Example 79.Example
Non-conformant activity order: S,C,A,B,D,E
The activity sequence starts with a wrong activity.
Example 80.Example
Non-conformant activity order: E,A,C,B,D,E
All steps of the activity sequence are completed, but no end event is reached. This indicates an incomplete process.
Example 81.Example
Non-conformant activity order: S,A,C,B,D
An activity in the activity sequence does not match any model task.
Example 82.Example
Process type Z occurs. If Z is not part of the model, any process that includes Z falls into this category.
Non-conformant activity order: S,A,C,B,Z,D,E
Note that due to the algorithmic complexity, the conformance issues are reported on a best-guess basis. This means that there may be more reasons for non-conformance than ARIS Process Mining reports.
