activity Instance count

\mathit{I}(c)

Dimension:

Time

Granularity:

Case

Number of times that any activity is instantiated in a case.

If the event log does not contain timestamps, activity Instance count can be used as a proxy for the time performance of a case.

A greater number of activity instances implies that the case takes longer to complete.
