Manufacturing resource planning

[2] This is not exclusively a software function, but the management of people skills, requiring a dedication to database accuracy, and sufficient computer resources.

The development of these manufacturing coordination and integration methods and tools made today's ERP systems possible.

MRP (and MRPII) evolved from the earliest commercial database management package developed by Gene Thomas at IBM in the 1960s.

In the 1980s, manufacturers developed systems for calculating the resource requirements of a production run based on sales forecasts.

Material requirements planning (MRP) was an early iteration of the integrated information systems vision.

MRP information systems helped managers determine the quantity and timing of raw materials purchases.

[5] Material requirements planning (MRP) and manufacturing resource planning (MRPII) are both incremental information integration business process strategies that are implemented using hardware and modular software applications linked to a central database that stores and delivers business data and information.

Paper-based information systems and non-integrated computer systems that provide paper or disk outputs result in many information errors, including missing data, redundant data, numerical errors that result from being incorrectly keyed into the system, incorrect calculations based on numerical errors, and bad decisions based on incorrect or old data.

Manufacturing Resource Planning or Management resource planning (or MRP2) - Around 1980, over-frequent changes in sales forecasts, entailing continual readjustments in production, as well as the unsuitability of the parameters fixed by the system, led MRP (Material Requirement Planning) to evolve into a new concept .
