Indicator

Identity Average TCO

Full Name

Average Total Cost of Ownership per Managed Active Identity

Version

1.2 Ready for peer review

Rationale

This indicator is an improvement of the https://open-measure.atlassian.net/wiki/spaces/IND/pages/158728703. It changes the measurement scale to the average TCO per identity, making the indicator comparable between organizations and through time. Here, per identity means per active identity managed by the organization.

Refer to https://open-measure.atlassian.net/wiki/spaces/IND/pages/158728703 for a discussion TCO applied to IAM and https://open-measure.atlassian.net/wiki/spaces/ART/pages/117670008 for a discussion on the measurement approach.

IAM is composed of process clusters that manage identities of highly different nature. It is doubtful that summing all these identities together would convey any valuable meaning, but TCO is highly relevant at cluster level (providing that the organization does manage these clusters). The Identity Average TCO indicator is composed of the following series:

  • Core Identity Average TCO = The average TCO of a core identity.

  • Privileged Identity TCO = The average TCO of a privileged identity.

  • Federated Identity TCO = The average TCO of a federated identity*.

  • Customer Identity TCO = The average TCO of a customer identity.

*. Doubts may be expressed on whether the identity is the right measurement unit in the context of identity federation. The organization level may be more appropriate.

Formula

cf. https://open-measure.atlassian.net/wiki/spaces/IND/pages/158728703 for the base indicator.

  • Core Identity Average TCO = Core IAM TCO / # core identities

  • Privileged Identity TCO = PAM TCO / # privileged identities

  • Federated Identity TCO = Federation IAM TCO / # federated identities

  • Customer Identity TCO = CIAM TCO / # customer identities

Parameters

Currency This indicator is expressed in the organization’s reference currency.

Benchmarking

This indicator is comparable between organizations.

This indicator is comparable across time.

If the TCO consolidates costs in multiple currencies, the effect of foreign exchange rates may be significant. Depending on the indicator’s usage (e.g. measuring global versus regional performance in large organizations), this effect need to be specifically accounted for (i.e. historical forex rates vs current forex rates).

Stakeholders

Scopes

In large organizations where IAM is organized in regions or otherwise, the indicator may be measured at both global and regional levels.

Negative Effects

cf. https://open-measure.atlassian.net/wiki/spaces/IND/pages/158728703 for TCO negative effects.

Data Sources
