99% of all software engineers need to be told exactly what functions to implement and where and how to name them and how to organize them in order to not produce something disgustingly oppositional to use and maintainance because they completely lack any aesthetic sense whatsoever for their craft. So management can decide which bridge they want to prioritize safety in and let an architect plan it first before the wrench jockey who doesn't know a cantilever from their elbow starts bolting holes.
I don't know if I answered your question as expected or not.
