Activity count

\mathit{A}(g)

Dimension:

Time

Granularity:

Group of cases

Number of activities that occur in a group of cases.

If the event log does not contain timestamps, Activity count can be used as a proxy for the time performance of a group of cases.

A greater number of activities implies that the cases in a group of cases take longer to complete.
