At a glance
If most people in a team hold a permission, that permission may belong in a role. It may also be a legacy grant that nobody removed. Role mining helps find patterns; business review determines which patterns should become policy.
- Understand the population before analysing it.
- Separate temporary exceptions from normal job needs.
- Test both the gains and removals caused by a proposed role.
Choose a coherent population
At the fictional Pine Harbour Foods, procurement staff in two locations use the same finance system. Their job titles match, but their approval limits and local responsibilities differ. Treating them as one undifferentiated peer group can hide a meaningful boundary.
Select a population whose work can be explained. Check whether inactive accounts, service accounts and temporary assignments are mixed into the data. The aim is not to remove every variation, but to understand what the variation represents.
Ask owners to explain candidate bundles
For each suggested role, ask which task the bundle supports and which permissions are essential. Remove historical exceptions from the proposed baseline unless there is a reason to make them standard. Give the role an owner and a description that someone outside the identity team can understand.
| Pattern | Possible interpretation |
|---|---|
| Nearly everyone has the permission | Common work, or an old broadly assigned permission. |
| One person has extra access | Specialist duty, temporary cover or unjustified access. |
| Two roles overlap heavily | Possible consolidation, unless a sensitive distinction matters. |
A statistical pattern does not tell you which interpretation is correct. Use the application owner’s knowledge and the original request or assignment context to resolve it.
Check the full access effect
A candidate role may be acceptable by itself but conflict with another role. Include direct entitlements and inherited memberships when reviewing the proposed outcome. A role model that ignores those paths may underestimate effective access.
IGAX’s published role-mining and peer-suggestion features can help develop candidates. Its policy and SoD capabilities are relevant to checking conflicts. Confirm the coverage and mappings in the deployment before assuming every application permission participates in those checks.
Pilot the change before expanding it
Compare intended memberships with current access. Ask owners to review important additions and removals. Test the result with a small population whose support needs are understood. Include a correction path if a legitimate task becomes unavailable.
After deployment, look at access requests and certification decisions. Repeated exceptions may show that the role does not fit the work. Repeated removal of the same entitlement may show that the bundle is too broad. Investigate before creating another near-duplicate role.
Do not judge success only by reducing the number of roles. Clear responsibilities and appropriate permissions matter more than a small catalogue. Some differences represent genuine business boundaries that should remain visible.
