On Standards. Revising, Retiring, Obsolete and the Exceptions
Obviously, there comes times when an organization's standards need to be revised, retired and make obsolete. And, there's always going o be that case (or many) when there needs to be an exception. Always.
Revising a Standard
A new version of an established Enterprise Architecture Program standard must progress through the full Enterprise Architecture Program standardization process as if it were a completely new specification. Once the new version receives the appropriate approvals, it will usually replace the previous version, which will be moved to historical status. The new version will retain the RFC number of the previous version.
However, in some cases, at the discretion of the Enterprise Architecture Office, both versions may remain as Enterprise Architecture Program standards to honor the requirements of an installed base. In this situation, the relationship between the previous and the new versions must be explicitly stated in the text of the new version.
