Being in the financial services business, I'm with you on this. Any program
change requires full regression testing, including "just a recompile". We do
not recompile at all once changed source code is tested by the developer and
moved into QA. All moves into QA and into Prod are just IEBCOPY operations.
Code is tested and quality assured as-is from the developer.
It is the developer's responsibility to make sure nothing broke and that new
function operates as specified. ABO does not change that mandate, so it had
better have been done before the developer performs the required testing and
certifies a change as "ready for QA".
The potential impact of an un-caught bug or even just an unexpected change in
business process behavior on the reputation and client base of a company is
immense and cannot be ignored (especially in this social-media-frenzied
environment), and I would venture to say that any any business type you care to
name has that same risk.

While I believe that ABO can very much help old COBOL modules (and even those
sites that don't
have corresponding source code), it is a change. Your industry may have
requirements. From a performance analyst perspective, I'd have much interest
in the before and
after effect of implanting ABO. Seems like a good session for SHARE for anyone
