How to Identify bottlenecks
Analyzing activity throughput
Perform this analysis to show the productivity of activities in a process. For each activity, this analysis displays the activity duration and the maximum quantity of work items that can be processed in an hour.
To carry out this analysis, you must have the process diagram that you want to analyze open in the Process editor.
Productivity is a core business measure. Many organizations need to analyze the production capability of an activity, which is the amount of work each activity can perform for a given period of time.
Understanding activity throughput enables you to evaluate and compare productivity measures between activities within a process. If there is a high degree of variance between the throughput of consecutive activities, this can create a potential for bottlenecks or underutilization.

Note: If an activity's processing time is specified as a distribution, this analysis will not evaluate the values. Distribution is used by simulation.To carry out the analysis, complete the following step:
Right-click the process diagram and select Static Analysis > Activity Throughput.
The analysis results appear in the Analysis view.
Activity throughput report
This report shows the results of an activity throughput analysis.
Note: You cannot generate this or other process model analysis reports from the Project Tree. You must complete the process model analysis and then generate your report from the Analysis view. Process model analysis provides information on the contents of a specific process model and therefore must be completed from the process diagram rather than from the Project Tree.

For each activity, this report displays the following information.
| Column or heading name | Description | Calculation |
|---|---|---|
| Activity | Name of the activity | |
| Elapsed Duration | The processing time specified for the activity | Processing time |
| Throughput | Number of times the activity can deliver output per hour | 1 / Elapsed Duration |
| Max Throughput | The maximum throughput for the activity based on the highest value calculated for Throughput or Maximum Throughput Due to Resource or Role | MAXIMUM (Throughput, Maximum Throughput Due to Resource or Role) for this activity |
| Notes | Any notes generated by the analysis relating to the current elapsed duration and throughput, such as "Elapsed duration could not be computed" | |
| Resources or Role Throughput: Name | The names of each resource and role the activity requires | |
| Resources or Role Throughput: Max: Throughput | The maximum attainable throughput for the activity if all available quantities of this bulk resource or role in the project are assigned to this activity
Note: No value will be displayed if you selected to run simulation without resource requirements. |
Throughput * available quantity of this resource or role / allocated quantity of this resource or role |
| Resources or Role Throughput: Notes | Any notes generated by the analysis relating to the requirement, such as "Available quantity is less than the allocated quantity for the bulk resource and role requirement" |

Activity throughput analysis
Activity throughput analysis determines the maximum number of work items that can be processed in an hour.
Note: If an activity's processing time is specified as a distribution, this analysis will not evaluate the values. Distribution is used by simulation.
Note: If an activity's processing time is specified as a distribution, this analysis will not evaluate the values. Distribution is used by simulation.
For each activity, this analysis displays the following information:
| Column name | Description | Calculation |
|---|---|---|
| Activity | The name of the activity | |
| Elapsed Duration | The processing time specified for the activity | Processing time |
| Throughput | The number of times the activity can deliver output per hour given that all resource and role requirements are met exactly | 1 / Elapsed Duration |
| Resource or Role | The names of each resource and role the activity requires | |
| Maximum Throughput Due to Resource or Role | The maximum attainable throughput for the activity assuming all available quantities of the required bulk resources or roles in the project are working to carry out this activity | Throughput * quantity of available resources or roles / quantity of the resource or role required by the activityFor example, if the throughput for an activity is 2, and it requires 3 resources, but 6 resources are available, then the value displayed in this column is 4. Throughput of 2 × 6 available resources / 3 required resources |
| Resource or Role Notes | Any notes generated by the analysis relating to the requirement, such as "Available quantity is less than the allocated quantity for the bulk resource and role requirement" | |
| Maximum Throughput | The maximum throughput for the activity based on the highest value calculated for Throughput or Maximum Throughput Due to Resource or Role. The larger of the two values is returned. | MAXIMUM (Throughput, Maximum Throughput Due to Resource or Role) for this activity |
| Notes | Any notes generated by the analysis relating to the current elapsed duration and throughput, such as "Elapsed duration could not be computed" |
