Why this matters
Bitkom places the ERP label as the early-1990s extension of MRP II. IHK Pfalz highlights cross-functional integration as the core characteristic. So the word describes an architectural decision more than a product.
A real-world example
Three vendors that were prominently featured in 2020 ERP top-ten lists no longer exist independently today. Brands come and go. The integrated data-model principle is the constant.

The structural principle most definitions omit
Thinking from first principles, the term survived four technological generations because the integrated data model is a structural — not a technological — principle. Saying "ERP" commits you to integration over best-of-breed. That decision is not reversible.
Today's ERP architecture still carries MRP heritage in its planning algorithms, bill-of-material structures and posting logic. Knowing those historical assumptions prevents costly category errors during selection, because terms and tools are not naively equated.
