I have to agree with Ralph.  IPC specs are great and provide the most
up-to-date information available.  IPC specs evolve quickly and are the
focus of much change activity, unlike the status quo of many older military
specs.  All this is terrific from a technology point of view but it does
make management of specifications and contract requirements very cumbersome.
Some of us are still building military and commercial hardware to very
specific design requirements.  Our customers are reluctant to change, which
locks us into old specifications.

Yes, we are trying to eliminate specific design requirements from our
contracts using the Single Process Initiative.  We have been successful in
many respects, but as soon as we get though this process we find the specs
have changed again.  All this requires a great deal of effort to inform
customers, update documentation, train employees, and bring suppliers
up-to-date.

With no comparison document or revision document it is difficult to
demonstrate to our customers why we should roll to the latest
specifications.  When we do finally get a requirements change we find the
requirements have changed again!  I don't want to stop progress, or even
slow it down.  I think all the changes are for the best in the long run, but
management of the changes with revision documents, providing the reason for
change, would make life a lot easier.
