ERP products are designed following "standard" or "best" practices/processes. It's common to see companies first contract a consulting company to "re-design" their processes before they then try to implement an ERP system.
...and yet there are all kinds of segments where customized tooling is more the norm than otherwise. It just depends on whether the deviation from the norm is a competitive disadvantage or a competitive advantage. There are a lot businesses where in at least one case, it is an advantage.
However, those that embark on deviating from the well-trodden path are going to be in trouble soon: after every update, potential changes made need to be re-done or edited or at least tested. So as the parent suggests it's really better to adjust the business process if you can.
That's another way of saying that there are serious trade-offs going that way that need to be justified... which may also be true for the path of adjusting the business process.
