Application score profiles

The indicators and their respective weights are used to calculate application score profiles for each configuration item. Use the score profile to calculate application scores and assess the applications. Apply these scores to compare applications and make strategic decisions about which ones to keep, replace, maintain, or invest more in.

You can use the preconfigured indicators or create indicators to retrieve their related data based on the frequency set at the indicator definition stage. This data is captured in the Application weight column of the Application Indicator Score [apm_app_indicator_score] table. The Target maximum and Target minimum that are set while creating an application indicator are for calculating the applications normalized value.

Note:

The Target maximum and Target minimum are not available when the data source is Assessments.

The normalized value of the application score, which is measured on a scale of 1–10, is derived from the following formula:

(Application Weight - Target minimum)/(Target maximum - Target minimum) * 9+1
Note:

If the Target maximum and Target minimum are not set, then the maximum value within the range of applications is taken as the target maximum value. Similarly, the minimum value within the range of applications is taken as the target minimum value.

The Application Weight that is lesser than or equal to the target minimum is given the lower score, which is 1.

The Application Weight that is greater than or equal to the target maximum is given the maximum score, which is 10.

When you set the application indicators, you can also configure the Direction as Maximize or Minimize. The application with the maximum value gets the minimum score when the direction is Minimize. The application with the minimum value gets the maximum score when the direction is Maximize.

If the Direction in the indicator is Minimize:

(10 - above calculated Normalized value)

Application profile weightage is then applied on the Normalized value to derive the Indicator Score:

Normalized Value * Weightage as in application score profile %

After the indicator score is calculated for each of the indicators, the application score is calculated by summing up all the indicator scores used in the profile.

In the figure, since the Costs and Incidents indicators are set to minimize, the applications with lower costs and lower numbers of incidents have higher scores.
