Enterprise Resource Planning

ERP
PlanningMFG-ERP-005

Enterprise Resource Planning (ERP) is a software system that integrates a company's core business functions into a single, shared database.

Definition

Enterprise Resource Planning (ERP) software centralizes information from different departments. It connects finance, human resources, manufacturing, and supply chain management. All data is stored in one database. This gives all departments access to the same, up-to-date information.

On the shop floor, an ERP system translates business plans into production activities. When a sales order is entered, the ERP checks material inventory and production capacity. It can then generate purchase orders for raw materials and create a master production schedule. This schedule informs the Manufacturing Execution System (MES) about what to produce and when.

The main purpose of an ERP is to create a single source of truth for the entire organization. It automates business processes and reduces the need for manual data entry between systems. This improves data accuracy and helps managers make decisions based on real-time information. It also standardizes processes across the company.

Implementing an ERP is a significant project. It requires mapping business processes, migrating data from old systems, and training employees. Companies can choose between on-premise servers or cloud-based software-as-a-service (SaaS) models. The choice depends on factors like cost, IT resources, and security requirements.

Example

A custom cabinet maker receives an order for 50 kitchen cabinet sets. The ERP system automatically checks the bill of materials, confirms there is enough maple wood and hardware in stock, and schedules the job on the CNC routers and assembly cells. As the work orders are completed, the system updates inventory levels and notifies the accounting module to generate an invoice.

Frequently Asked Questions

What is the difference between an ERP and an MES?

ERP systems manage business-level operations like finance, sales, and inventory. Manufacturing Execution Systems (MES) manage real-time production activities directly on the shop floor.

Do small manufacturing businesses need an ERP?

Yes, many cloud-based ERPs are designed for small and mid-size businesses. They can help standardize processes and prepare the company for growth.

How long does it take to implement an ERP system?

Implementation time varies based on company size and complexity. It can take anywhere from 6 months to over 18 months.

Can an ERP connect to shop floor equipment?

An ERP typically connects to an MES or other shop floor software, which in turn connects to machines. Direct connection is less common but possible through APIs and middleware.

What are the main modules in a manufacturing ERP?

Common modules include inventory management, bill of materials (BOM), production scheduling, material requirements planning (MRP), purchasing, and finance.
