I have the feeling that we are at the MRP stage (https://en.wikipedia.org/wiki/Material_requirements_planning https://en.wikipedia.org/wiki/Material_requirements_planning) when companies started using computers but writing software to handle production processes was so new that nobody could write anything truly universal. The next will be the ERP stage where we know some abstractions that apply to many companies, companies like SAP can sell some software - but most money is in 'implementation' by consulting agencies.
