All of which brings us back to “identity management.” Gaining an understanding of identity management should not simply occur by reading vendor product marketing literature (though I know it often does). The “learning curve” on identity seems to almost always include: A) a small-ish project initiated to achieve a business process goal (i.e., eliminate X costs associated with Y redundant sign-ins); B) a realization by the implementing team that there’s a wider identity problem that they must fully grasp if they are to scale any success; and C) a gradual reworking of the architectural principles of the IT organization that makes identity the foundational and organizing paradigm.So, how should one come to *understand* what identity management is? Begin by understanding the breadth and depth to which identity as a concept must be used as an architectural principle.
