A Clean Enterprise is an enterprise, in which all the information available is fully integrated. From a technical view every application can access every information electronically accessible. Any user can access every information electronically accessible through an interface.
From the management and other decision-maker's point of view this an improvement, because they have a better knowledge of the facts to make their decisions.
Regarding privacy it raises an issue, as private information should not appear on any interface accessible from to every person. One must be able to tag such information and assure that it is not visible to other people.
-  Not only about Clean Enterprise, but gives a better idea what a Clean Enterprise can be.
