8. CONCLUSION
MRP is the part of ERP that deals specifically with the control and management of manufacturing inventories and the products produced by those inventories. While MRP has universally applicable elements, its ultimate success is intimately related to some important aspects of your overall manufacturing operations, which must be carefully analyzed.. But it causes high costs and technical complexities in implementation. In addition, organizations, which use an MRP system need to spend considerable effort on installing necessary equipment (computers), training personnel, modifying the software to serve their specific needs, validating, testing, and eliminating possible errors, and maintaining the software. The time required for planning and implementing an MRP system is generally very long. Data entry and file maintenance requires considerable inputs in the form of training and education of the personnel. Dependence on forecast values and estimated lead-time can sometimes be misleading. Despite all these facts, MRP is based on the fact that the demand for materials, parts, and components depends on the demand for an end product. With the advent of such systems, production efficiency could be greatly improved.
