01Define the boundary
Identify the actor, target resource and operation that multi-role support is meant to govern.
02Configure the policy
Keep role assignments distinct, define how multiple grants combine, and test both conflict and removal cases. Ensure that role selection does not bypass network or assurance requirements attached to the underlying access.
03Exercise the edge cases
An employee has a reviewer role for one resource and an operator role for another; the effective access is evaluated in the relevant resource context. Also test the path that should be denied, deferred or sent for review.
04Review the outcome
Check that the resulting state is understandable and that the decision can be investigated later. For audit-enabled operations, confirm the relevant actor and context are captured.
