Exercise

The downside of refusals

In the last exercise, we looked at the cases in which we didn't restart the procedure or didn't decline candidates. In these cases, it seems that the vacancies were filled slightly faster. But what is the impact when the candidate refuses our proposals?

filter_precedence() can be used to select cases based on specific orders between activities by providing antecedent and consequent activities.

Its usage is

dataset %>%
  filter_precedence(
    antecedents = "activity that came before",
    consequents = "activity that came after",
    precedence_type = "directly or eventually following?"
    filter_method = "all or none?"
  )

  • Filter for the cases in which "Receive Response" is never followed directly by "Review Non Acceptance". Store it in not_refused. This can be done by setting precedence_type to "directly_follows" and filter_method to "none".
  • The cases in not_refused still have a high throughput time. Let's select those cases of not_refused which take longer than 300 days. Store them in worst_cases.
  • Use trace_explorer() to look at the 80% most frequent different traces in the worst_cases event log.
