Final answer:
ERPs and MRPs have different origins and purposes, with ERP integrating various functions and MRP focusing on managing production and inventory.
Step-by-step explanation:
The correct statement is d. None of the above is true. ERP (Enterprise Resource Planning) and MRP (Material Requirements Planning) are both systems used in manufacturing, but they have different origins and purposes.
ERP evolved from independent software systems used in different departments of a company. It integrates various functions such as finance, HR, sales, and production into a single system. MRP, on the other hand, is a system that focuses specifically on managing production and inventory.
MRP ll (Manufacturing Resource Planning) is an extension of MRP that includes additional functions such as capacity planning and shop floor control, but it did not evolve directly from ERP or vice versa.
