What does the throughput time represent when viewing selected variants?

Throughput time represents the total time taken for all cases that follow a specific process variant from the start to the finish. When examining selected variants, it encompasses the entirety of cases associated with that variant, regardless of whether they are completed or still in progress. This metric provides a comprehensive view of the efficiency and performance of the selected variant, allowing stakeholders to assess areas for improvement or the overall effectiveness of the process.

The other options focus on narrower scopes, such as only completed cases or specific activities, which do not capture the full range of time and performance for all cases in a selected variant. In particular, concentrating solely on completed cases would exclude valuable insights from those that are still ongoing, while limiting the view to specific activities wouldn't reflect the entire process flow. Additionally, considering only the longest case time would not provide a holistic view of the entire throughput time for all cases in the variant.
