Thunder!

An interesting article from the CEO of Thor Technologies, it does a very good job of outlining identity management's value proposition.

Quoting:

With automated enterprise provisioning, new systems and applications as well as new business rules are easily added. IT departments can quickly regain control over a changing environment. A rationalized IT department can also reap significant savings on expensive software licenses. It is very common, for example, that a merger or consolidation of business units results in layoffs, and a company finds itself with far more software licenses than users. However, manually tracking down all the user accounts and verifying the required number of licenses is extremely tedious and time consuming. With automated provisioning, a company can quickly determine the required number licenses and reduce its license fees accordingly.
