Rework

When looking at the structure of a process, an interesting aspect to look at is rework. Rework happens when the same activity is repeated within a single case, which often points towards time and resources which are wasted, and typically a mistake which has to be rectified.

We can distinguish between two different types of rework: 1) immediate rework, we are also known as self-loops of activities, and 2) rework which surfaces later in the process, which we call repetitions. In this exercise, we will focus on the latter.

The number_of_repetitions is a metric which can be calculated for

  • the whole event "log",
  • each "case",
  • each "activity",
  • each "resource", or
  • each "resource-activity" pair.

Use the number_of_repetitions() metric with the appropriate level argument to answer each question for the sepsis process.

  • What are the minimum, maximum and average number of repetitions in the process over the whole event log?
  • Who is most responsible for repetitions, i.e. which resource?
  • Which activity has the most repetitions?
