Model conformance

Uploading a reference model

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:

1. To view the Model conformance panel, select the icon from the taskbar on the header.

2. Click Upload reference model.

3. In the Add reference model dialog box, upload and add the file.

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

Visualizing the process

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

1. In the Model view options section of 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.

2. In the Case State dropdown, select one of the following options:

   • To show the confromance analysis of the completed cases, click Completed.
   • To show the confromance analysis of the running cases, click Running.

By default, the Case State dropdown selects the Completed option to display the conformance analysis of the completed cases.

When you select the Compare both models model view, a Compare both models legend appears in the process area. You can use the Compare both models legend to view the following information:

• 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 blue box, both dark and light color variant, 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 that the process has on average when the deviation occurs.
• The average cost of the cases in which the deviation occurs.
• The average throughput time of the cases in which the deviation occurs.

To view the deviation values, in the Deviations dropdown click one or all of the following checkboxes:

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.

Viewing the root cause analysis

In the Reference model deviation section, you can select a specific unexpected activity or process flow and view information that is related to potential root cause.

For every detected root-cause condition, you can view the following information:

Frequency of cases
Indicates the percentage of cases where the root-cause is verified when compared to the total number of cases where the deviation occurs.

Correlation strength
Indicates whether the correlation strength is strong, medium, or weak.

The strength of the correlation is reduced for the following cases:

Lack of precision
Instances where the root-cause condition matches and the deviation does not occur. Lack of coverage
Instances where the root-cause condition does not match and the deviation occurs.

To view the information that is related to root cause analysis, do the following steps:

1. In the Reference model deviation panel, select the menu icon in the tile of the deviation

2. Click View root cause analysis.

Creating filters to include or exclude a case

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

In the Reference model deviation panel, select the menu icon in the tile of the deviation, then do 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.
