Using the Heatmap

When you click the Flow icon for a process in the Application Overview page, a color-coded Flow View or Heatmap is displayed.
A heatmap helps a Manager to:
*Get an overview of the status of the currently active instances. Using this as a tool a business manager can identify potential bottlenecks in the process.
*Identify worksteps that have been suspended, for a variety of reasons and take necessary actions to resume the suspended processes.
*Analyze the history of the completed instances to identify potential trends and opportunities for optimization.
In the Flow View, you can use the Process Instance Status drop-down list to filter the instances and Workstep Status drop-down list to filter the worksteps in the heatmap based on their status. You can select Completed from the PI Status, select Activated, Suspended or Completed or Monitoring wait from the Workstep Status, and then click Go, or select Activated from the PI Status, select Activated, Suspended or Completed from the Workstep Status, and then click Go. The heatmap graphically shows the status of all worksteps for the specified status of process instances. For example, if you select Activated from the PI Status drop-down list, Suspended from the Workstep Status drop-down list and click Go, then the heatmap displays all suspended worksteps of all the active process instances. When you change the Process Instance Status option, it automatically updates the options in the Workstep Status drop-down list. However, to refresh the heatmap, you need to select the PI Status option, select Workstep Status option, and then click Go.
Each workstep is color-coded as described in the following table.
Table 11. Heatmap Color Coding
Color Range
Red to Green
For values between the maximum and the median.1
Green to Blue
For values between the median and the minimum.

1 Median is calculated by adding all the values for each activity and dividing this sum by the total number of activities.

The legend in a heatmap does not display all the bin colors. It displays only the colors that are used in that heatmap.
The number in the parenthesis after the activity label indicates the total number of workstep instances of the specified status.
A bottleneck can be identified by a red workstep immediately followed by one or more green worksteps.
