Do you need an MRP system or an ERP system?

Determining whether an MRP (Material Requirements Planning) or ERP (Enterprise Resource Planning) system is more suitable for your needs is essential for finding a budget-friendly option. MRP systems are central to scheduling and planning production in factories.

Their principal role lies in calculating the types and quantities of materials required for production and the optimal timing for their procurement. By doing so, MRP systems help avert production downtime and enhance operational efficiency.

Enterprise Resource Planning (ERP) systems offer many of the same capabilities that MRP systems have but with the addition of broader functionality that caters to wider business processes. Below we explain what MRP systems are, and also explore how they differentiate from ERP systems.

The Importance Of MRP Systems

MRP systems assist manufacturers in several key business areas such as:

  1. Ensuring timely availability of materials for production: MRP systems forecast the materials needed for production, helping to avoid delays due to shortages. This optimises asset use and cuts emergency sourcing costs.
  2. Guaranteeing product delivery to clients: MRP synchronises production and delivery schedules, ensuring commitments to clients are met. This boosts customer satisfaction and competitive standing.
  3. Regulating inventory levels for raw materials and finished goods: MRP maintains optimal inventory levels, balancing storage costs with availability. This avoids wastage and missed sales opportunities.
  4. Orchestrating various elements of manufacturing, from sales orders to procurement activities: MRP integrates sales, procurement, and production, converting sales orders into production tasks and alerting procurement as needed. This improves operational cohesion.
  5. Optimising Operational Efficiency: MRP systems provide real-time data and analytics, allowing businesses to adjust their manufacturing processes as needed. This enables greater efficiencies in terms of labour, machine time, and resource allocation.

The Evolution of MRP Systems

Originally, MRP systems were tailored for mass production. However, the escalating global competition demanded the delivery of customised products, thereby requiring a more sophisticated management system. This led to the emergence of MRP II systems, which integrated additional functionalities like financial management and quality assurance, thereby offering a holistic approach to product lifecycle management.


The Introduction of ERP Systems

Enterprise Resource Planning (ERP) systems are an extension of MRP II systems, having a broader impact on the organisation as a whole. ERP integrates an array of business processes including financials, human resources, customer management and key MRP functionalities, into a unified system. Depending on size and needs, organisations may opt for a suite of interconnected ERP applications or Software as a Service (SaaS) solutions.

Should You Choose an MRP or ERP System?

When choosing between an MRP or ERP system, consider that MRP focuses solely on material management, whilst ERP systems encompass a variety of back-office functions. MRP is generally a standalone system, its scope confined primarily to manufacturing. ERP systems, on the other hand, are designed to integrate easily with other systems and serve a much broader array of departments within an organisation.
