The interval panel allows user to specify two activities and then calculate the time between them. Since there could be several consecutive events of the same activity, a user should specify how to handle such case.
To define From, a user first specifies the activity, using the standard activity selector in a popup window. Then user may change the configuration for “If several consecutive” which is the drop-down list with 3 options:
• Use first one
• Use last one
• Use average
Exactly the same configuration exists for To configuration.
Once From and To are defined, user can see the histogram. Then user could specify the breakdown dimension and see the Trellis charts.
User may create the filter on the time interval using the histogram sliders. User may also create a filter by dimension
As always with similar viewpoints, the histogram will display the minimum, maximum, and average values as well as the distribution for the time interval.
By selecting the first one that means the tool will measure the time from the first occurrence, whereas the last one would measure the last time the event occurred. Remember events can occur numerous times in a process timeline.
So in the below example there can be numerous lab orders happening, so respectively there would be numerous lab orders being returned. In the below example, we are interested in the last time a lab is resulted and measuring the time between the first lab order and the last time a lab order is returned.
