Organizations having a large number of employees face several difficulties to separate job assignments to individual users. The situation becomes more complex when job assignments are delegated to those users who fulfill some explicit conditions. The delegation models developed so far discuss various issues regarding delegation of roles, but no mechanism has been developed to specify and validate constraints which are applied in course of temporary delegating (temporal delegation) and revoking a role to and from a user. This paper proposes a validation mechanism for flexible delegation and revocation of job roles to and from users with specific conditions. Also, the author attempts to specify and validate n-level delegation and cascading/non-cascading revocation processes in an organization.
