Model conformance

You can do a visual conformance check between the data-derived model and the reference model using the Model conformance panel. You can also compare the models to analyze the similarities and the differences.

You can visualize the following fitness and conformance indicators by using the Model conformance panel:

Similarity: Indicates the percentage of similarity between the data-derived model and the reference model.
Fitness: Indicates the percentage of represented cases in the data-derived model.
Minimum fitness: Indicates the percentage of least similar cases when you compare the data-derived model to a reference model.
Maximum fitness: Indicates the percentage of most similar cases when you compare the data-derived model to a reference model.

Note: The process model might hide some of the cases based on the activity and relation complexities that are selected in the Model detail section of the View mode pane. The values for Fitness, Minimum fitness, and Maximum fitness varies based on the value for activity and relation complexity.

Uploading a reference model

Important: You can upload a reference model to a process-mining project only if you are the owner of the project.

To use the features of the Model Conformance panel, you have to upload a reference model.

To upload a reference model, do the following steps:

On the process page, click the Conformance button.
Click Upload reference model.
Upload a file, or select a file from the business repository.
Click Add reference model.

Visualizing the process

To visualize the process by basing it based various models, do the following steps:

In the Model conformance panel, do one of the following steps:
- To visualize the process model for the created project, click Data derived model.
- To visualize the activities in the reference model, click Reference model .
- To visualize the differences that are observed in the data derived model when compared to the reference model, click Compare both models.
In the Case State drop down list, select one of the following options:
- To show the conformance analysis of the completed cases, click Completed.
- To show the conformance analysis of the running cases, click Running.

Note: By default, the Case State drop down list selects the Completed option to display the conformance analysis of the completed cases.

In the Compare both models option, the following elements are included:

A red box or arrow in the process model indicates that the activity or transition is present only in the data derived model.
A yellow box or arrow in the process model indicates that the activity or transition is present only in the reference model.
A box in the color of currently selected view (like frequency, duration, cost) indicates that the activity is present in both the models.
A black arrow indicates that the transition is present in both models.

Analyzing the conformant cases

You can use the Conformant cases section in the Model conformance panel to view the following information:

Number of conformant and non-conformant cases: A case is called conformant when every activity is compliant with the reference model.
Steps per case: Indicates the average number of steps per case for both conformant and non-conformant cases.
Case cost (Unit of currency): Indicates the average case cost for both conformant and non-conformant cases and indicates the unit of currency that is selected in the Data & Settings tab.
Average case lead time: Indicates the average throughput time of both conformant and non-conformant cases.

Analyzing the deviations

You can use the Reference model deviations section in the Model conformance panel to analyze the deviations in the data derived model. These deviations can include unexpected activities, unexpected initial activities, and unexpected process flows.

The Reference model deviations section provides the following information:

The percentage of deviation that occurs in the process variants.
The number of cases in which the deviation occurs.
The count of activities (steps) that the process has on average when the deviation occurs.
The average cost of the cases in which the deviation occurs.
The average lead time of the cases in which the deviation occurs.

To choose which deviations to display, select front the following options in the Deviations drop down list:

Unexpected activities: You can visualize the complete list of unexpected activities or steps in the process model.
Unexpected initial activities: You can visualize the complete list of unexpected initial steps in the process model.
Unexpected process flow: You can visualize the complete list of unexpected process flows in the process model.

Creating filters to include or exclude a deviation case

You can use the Reference model deviations section to filter a process for a specific deviation and visualize only the cases that include or exclude the deviations.

Open the Model conformance panel.
On the deviation tile, click the menu button.
Perform one of the following steps:
- To visualize the cases that include the deviation, click Create filter including case.
- To visualize the cases that do not include the deviation, click Create filter excluding case.
