Definition
The number of application instances
Components
Application Instance | cf. https://open-measure.atlassian.net/wiki/spaces/DIC/pages/834044036. |
|---|---|
Entity | The organization or organizational unit for whom performance is being measured. |
Scope of responsibility | An application instance is within the scope of responsibility of an entity when that entity owns the instance, or has been delegated responsibilities in relation with the instance. |
Rationale
Knowing the number of application instances within an entity’s scope of responsibility is of critical importance to assure that this responsibility is fulfilled, whatever the responsibility is.
Limitations and Complexities
By definition, applications whose existence is not known cannot be accounted for. This limitation may constitute a risk in environments where data quality in inventories is not reliable.
In a complex environment with multiple entities having shared responsibilities across application instances (e.g. complex out-sourcing setups), responsibility scopes may be difficult to clarify.
Data Sources
Cloud Services Inventories
CMDBs
IT Applications Inventories
Third Parties Inventories
Formula
Let K be the set of known application instances.
Let e be the entity.
Let R be a set of responsibilities assigned to e.
Let s(K, e, R) = A be defined as the function that returns A, a subset of K where for each application instance a in A, the entity e has at least some responsibility in R.
The formula for the indicator is then: i = |s(K, e, R)|
