The right person on the job faster

We just saw that certain activities are often repeated in the process. In order to solve the throughput time problem, it seems we need to get a better idea of the process.

Before, we used normal process maps with type = frequency() as well as performance maps with type = performance(). However, we can also mix them by setting the type_edges and type_nodes arguments separately, allowing us to look at different aspects simultaneously.

Sometimes viewing all the activities can make the process map difficult to read. You can use filter_activity_frequency() to simplify the dataset by filtering on only the most frequent activities. In the next chapter, you'll learn more about filters.

Visualize the vacancies process by constructing a process map.

  • The nodes should show absolute frequencies by setting type_nodes to a call to frequency().
  • The edges should show mean daily throughput times between activities by setting type_edges to a call to performance() with arguments mean and "days".
