This page introduces the concept of a variant in Process Mining, discusses why they're useful, and explains how to interpret variants within a process.
Under ideal circumstances, a process is completed from start to end in the same way every time. Activities are performed in the same order, take the same amount of time, and lead to the same outcome. But circumstances are rarely the same every time, which means that the process might not happen the same way each time.
A variant is when a particular process instance is different from a defined process. For example, consider a hotel check-in process:
These four steps comprise the ideal process from start to finish. But what happens if there is no available room? Now there's another step:
Now there are two additional steps in the process that cost both time and money. The front desk worker must spend more time to locate an available room and negotiate with the guest to determine if the change is acceptable. This also costs money by requiring a price adjustment for a room that's cheaper than the one reserved originally.
This adjust process completed successfully, but it's not the ideal version. The second version of this process, with the additional steps, is an example of a variant.
The variant page displays all your process variants. You can use filters or the search function to change the variants and information that appear on this page. If not all variants appear, you can adjust the settings in the Number of Variant Groups filter.
This page displays information such as:
Click the column headers to change how the data is sorted.
If a target model is available, the activities are highlighted in specific colors:
If not all activities of the process are displayed in the panel, you can scroll left or right through the process to see the remaining activities.
To download the list of variants, open the Export Menu in the toolbar. Click Export CSV. The file downloads to your computer.
To see a list of all cases that have run through a process variant, click the variant name.
The list includes details such as:
For cases with many attributes, use the scroll bar at the bottom to view more information.
A case attribute is a piece of data that is true for the whole execution. Attributes are independent from the executed activities. For example, if your business produces cars, the engine type or the side of the steering wheel would be attributes. Values for a case attribute can change from case to case.
The arrow in the upper left-hand corner of the screen takes you back to the previous view (variant overview).
To view detailed information about specific case, click the case name.
The list shows:
To view more information about the attributes, click Show all attributes next to the number in the Attributes column. Click Hide attributes to collapse this information.
An event attribute is a piece of data in a single event that is true for only one execution of this event. Due to this, the count of an event attribute can be higher than the case count of the log. For example, the employee who executed the event or the system where the event occurred would be event attributes. Values for an event attribute can change from event execution to event execution.
To navigate the pages in the list, use the options below the list. 10 activities appear on each page by default, but you can change this value. The arrow in the upper left-hand corner of the screen takes you back to the previous view (list of cases).
To export the list, click the download icon in the top right corner and select Export case table. The list is exported as a CSV file containing all the variants selected by the current filters.
To help focus your analysis, you can filter the variants to display only graphics, statistics, or metrics for the selected variants.Use the checkboxes to select the variants of interest.
