Assign the CI Significance in the Service

Significance indicates the importance of a CI to related items in a service, and therefore influences the impact of a CI condition on those related items. It is a value from 1 through 10, where 1 is the least significant and 10 is the most significant. You can set global significance for CI types, and you can set significance for individual CIs and relationships in a service.

Consider the following:

• When you set global significance, it applies to new CIs that you create after the change. Existing CIs retain the previous significance for the type.
• Before you change the significance for a service, verify that all relationships are established. If you change a relationship later, the significance reverts to the default for the CI type.
• When you change significance for an individual CI in a service, the CI's significance value only changes within that service. If the CI belongs to other services, it retains its previous significance value in those services. This behavior helps ensure that you can maintain different significance values for the same CI if it is more or less important to other services.

Follow these steps: (global type significance)

1. Start the Operations Console, and select Tools, Default Significance.

   The Global Significance Editor dialog opens, showing the default significance for each CI type.

2. Adjust the slider for the types whose significance you want to change, and click OK.

   The global significance changes.

Follow these steps: (individual CI significance)

1. Open the Service Modeler.
2. Right-click a CI or relationship on the Topology tab, select Assign Significance, Set from the shortcut menu, and select a number from 1 to 10.

   The previous significance is replaced. The relationship text in the Modeler displays the significance of the relationship between the connected CIs.
