About this task

Formulas are often used to:
  • Calculate ratios and percentages.
  • Combine data from different applications.
  • Build predictive indicators based on historic performance.
Note: You must have Performance Analytics to create indicators.


  1. Navigate to Performance Analytics > Formula Indicators.
    The fields of a formula indicator are similar to an automated indicator except for the condition. Formulas can consist of other indicators, constants, and time series, or any combination of these.
  2. In the Formula section of the Indicators form, click the Browse for an indicator link.
  3. Select an Indicator to display.
    Note: You cannot delete any indicators, such as automated indicators, that are used in a formula. You must change or delete the formula indicator before you can delete any indicators used in the formula.
  4. (Optional) Select a Breakdown and breakdown Element to filter the indicator data.
    You can select an additional breakdown and breakdown element to further filter the data.
  5. (Optional) Select a Default time series to use when aggregating the data.
  6. (Optional) Select the Apply time series to result check box.

    When selected, the indicator calculates the formula first, then applies the time series calculation to the result. For example, when calculating the weekly average incident resolution time using the formula Total time to resolve incidents / total incidents resolved, the formula first calculates the average incident resolution time for each day, then the average of those times. Each day is given equal weight, leading to an unweighted average.

    When cleared, the indicator applies the time series to each component individually before calculating the score. Using the average incident resolution time example, clearing the check box results in a weighted average. The formula first calculates the weekly sum of the total time to resolve incidents and the weekly total number of incidents, then uses those values to calculate the weekly average time to resolution.

  7. (Optional) Clear the Allow breakdowns check box to prevent breakdowns from applying to this formula component.
  8. Click Select.
    The Formula field is automatically populated based on your selections.
  9. Modify the Formula as needed. Enter any operators or numbers to include in the formula. Use valid operator symbols, such as +, -, /, %, >, <.

    For example, if you want to calculate the average age of open incidents based on summed age of open incidents and number of open incidents, you could use the following formula: [[Summed age of open incidents]] / [[Open incidents]] / 24

    Formulas support multi-level breakdowns. For indicators that have Collect breakdown matrix enabled, it is possible to drill down to the second level in the detailed scorecard on the Breakdowns tab. For example, Closed incidents by Category, and then by Priority, or vice versa.
