Overview of the bubble chart

Select the application rationalization icon () and select the Bubble chart tab to view the bubble chart view of all business applications.

Use the bubble chart to view indicator scores of business applications in the X and Y axes and specify the bubble sizes. You can use these scores to measure how your applications are aligned to your business strategy and then create demands for the applications.

You can also generate insights into business applications using Now Assist. For information, see Generate insights into business applications.

Bubbles displayed on the chart

The bubble chart displays only the assessed business applications. Also, business applications marked as Retired or in End of Life lifecycle stage aren’t displayed on the Application Rationalization bubble chart page. However, you can view those business applications by updating the sn_apm_ws.business_application_default_filter system property. Contact your ServiceNow® account service manager to update the system property. Therefore, the number of bubbles displayed on the chart can be different from the number of business applications displayed on the list view page.

The total number of business applications displayed as bubbles on the bubble chart page is displayed at the top of the chart. You can also select the bubble count details icon () to view a detailed calculation of the number of bubbles displayed on the bubble chart page.

Understanding the bubble chart

On selecting a bubble, the business application data associated with that bubble is displayed in the info pane.

Business application bubbles whose X and Y-axis values are within the value range of +/-0.25 of each other, are grouped. A grouped bubble displays the total number of business application bubbles that it contains. One selecting a grouped bubble, the info pane appears, displaying the list of individual business applications that are part of the grouped bubble. On selecting a particular business application card, the associated business application data is displayed in the info pane.

The bubble color is dependent on the planned disposition value that was already set for the business application. You can refer to the legend displayed on the bubble chart to see the significance of each color.

The bubbles are of different sizes, based on the indicator score values that you select.

All the indicator scores are displayed according to the latest fiscal period, by default. The latest fiscal period is derived from the apm_app_indicator_score list. The duration of a fiscal period is derived from the system property com.glide.fiscal_calendar.fiscal_unit. You can also select a different fiscal period from the Scores for fiscal period list. Your fiscal period preferences are saved and applied the next time you visit the page.

The bubble chart displays up to 500 bubbles representing business applications, by default. If you want to see more than 500 bubbles, you can configure the sn_apm_ws.appRationalizationMaximumBubbles system property. For details, see Change the number of bubbles displayed on the bubble chart.

You can use the available filters to reduce the number of business application bubbles displayed on-screen. You can use the advanced filter to find business applications by applying specific criteria, such as application details, application indicators and scores, and associated business capabilities. Your filter preferences are saved and applied the next time you visit the page.

For more information, see Apply filters on the Application Rationalization page.
