You can use the critical path projection within the critical path management tool in Process Portal to identify different paths through a process. With this information you can analyze how long it will take to complete the process under different circumstances.
Projected path | Description | Data used to calculate the path |
---|---|---|
Optimistic | When one or more paths can be calculated for a process, the path that takes the least amount of time to complete is the optimistic path. | The shortest path is calculated using the durations and due dates of each pending activity. |
Pessimistic | When one or more paths can be calculated for a process, the path that takes the most time to complete (excluding loops) is the pessimistic path. | The longest path is calculated using the durations and due dates of each pending activity. |
Historical | When one or more paths can be calculated for a process, this is the path most likely to be taken based on past executions. | Performing a historical projection requires
that the process has autotracking enabled and tracking definitions
must have been sent to Business Performance Data Warehouse before
instances of the processes started running. Historical projections
are not valid if data does not exist in Business Performance Data
Warehouse for the current process. You can select that you want to use for your projection from the Historical Scenario list |
When you change the projection, the Projected Due Date changes in the Instance Details section to show the impact of the projected path on the duration of the entire process. Also, the Critical Path Management section displays the milestones, activities, and tasks that are relevant to the projected path you have selected.
