Definition
Number of digital identities within the scope of responsibility of the entity.
Components
Digital identity | |
|---|---|
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. |
TODO
- Distinguish Entity Count from ID Count
- The IDs of an Entity may be spread across multiple systems
- Distringuish counting primary identities from secondary identites
Rationale
Knowing the number of digital identities within an entity’s scope of responsibility is of critical importance to assure the fulfillment of this responsibility, whatever the responsibility consist in.
Limitations and Complexities
[] Speak about replication of ID thourgh systems, directories, metadirectories and federation, etc. What to count?
Data Sources
Formula
Let X be the set of known identity repositories.
Let e be the entity.
Let R be a set of responsibilities assigned to e.
Let s(X, e, R) = Y be defined as the function that returns Y, a subset of X where for each digital identity y in Y, the entity e has at least some responsibility in R.
The formula for the indicator is then: i = |s(X, e, R)|
