What is ERP?
ERP stands for enterprise resource planning, a term coined by the Gartner Group in the early 1990s to describe integrated business software that connects processes across an entire organization rather than managing them in separate, disconnected systems.
ERP traces its roots to material requirements planning, or MRP, systems developed in manufacturing during the 1960s. As those systems expanded to cover broader manufacturing resources, they became known as MRP II, and as they further expanded to cover finance, human resources, sales and other business-wide functions, the term ERP emerged to reflect this wider scope.
Modern ERP systems for manufacturers typically include MRP as one module alongside inventory management, purchasing, sales, shipping, invoicing, accounting and customer management, all sharing the same underlying data so information does not need to be re-entered across separate tools.
Why is ERP important?
Without an integrated ERP system, organizations often rely on disconnected spreadsheets and standalone tools for different functions, creating duplicate data entry, inconsistent information and delayed visibility into overall business performance.
A connected ERP system ensures that a change in one area, such as a new sales order, automatically ripples through related processes, such as inventory allocation and production scheduling, without requiring manual coordination.
Because ERP centralizes data across the business, it also supports better decision-making, giving leadership a unified view of finances, operations and customer activity rather than reconciling separate reports from disconnected systems.
How does ERP work?
A typical ERP system integrates these core areas:
- Manufacturing and MRP. Plan material requirements, production schedules and work orders.
- Inventory and purchasing. Track inventory levels and manage supplier purchase orders.
- Sales and customer management. Manage quotes, orders and customer relationships.
- Shipping and invoicing. Fulfill orders and generate customer billing.
- Accounting. Maintain the general ledger, accounts payable and receivable.
- Reporting. Provide visibility across all connected functions from one system.

| Relationship | Typically includes MRP as one module | Can operate standalone or as part of an ERP system |
Real-world examples of ERP
A manufacturer uses its ERP system to convert an approved sales order directly into a production work order, automatically reserving the required inventory and updating financial projections in one connected flow.
A multi-site manufacturer relies on ERP to unify operations across several locations, giving leadership consolidated visibility into inventory, sales and financial performance across the entire organization.
A growing job shop transitions from separate spreadsheets for quoting, inventory and accounting to a single ERP system, eliminating duplicate data entry and reducing errors across departments.
Regulations and standards related to ERP
ERP is not itself a regulatory requirement, but for regulated manufacturers, an ERP system that integrates with a compliant QMS can support broader traceability and audit readiness expectations found in standards such as ISO 13485 and AS9100.

Common mistakes with ERP
Common mistakes include implementing ERP but continuing to maintain parallel spreadsheets for certain functions, recreating the data fragmentation ERP is meant to eliminate.
Other problems include underestimating the implementation effort required, since ERP systems touch many departments and typically require careful planning, data migration and training to be adopted successfully.
