The aforementioned Lubri-Moly issue is a case of #4, sort of.  The idea was
that by moving from proprietary applications designed specifically for that
business to commercial general-purpose business applications that there would
be cost savings in software maintenance, and that the software would in the
end be more flexible.

This is not the case, as anyone who has ever seen an SAP disaster can attest.
