What is factory management software?

Factory management software (often called a manufacturing execution system, or MES) collects data from machines and operators and links it to orders, materials, quality records and maintenance. It tells you what is being made, how well, and why when something goes wrong.

What is OEE?

Overall Equipment Effectiveness measures how much of your planned production time is truly productive. It multiplies three factors:

  • Availability — run time divided by planned production time
  • Performance — actual output speed versus ideal speed
  • Quality — good units divided by total units

Example: 92% availability × 88% performance × 99% quality ≈ 80% OEE. Tracking the three factors shows whether losses come from stops, slow running or defects.

Core modules

  • Production planning and work orders
  • Machine data and OEE
  • Quality, inspection and traceability (batch and serial genealogy)
  • Maintenance management (planned and corrective)
  • Inventory and materials
  • Dashboards, reports and integrations with ERP

How to choose a system

  • Start with your biggest losses: downtime, scrap, changeovers or missing records
  • Check it can connect to your machines and existing systems
  • Prefer configurable workflows over heavy custom code
  • Ensure operators can use it easily on the floor
  • Plan training and support, not just installation

Implementing it

Map your process, connect a pilot line, configure work orders and quality checks, train operators, then expand line by line. Our factory management software is configured as part of a turnkey build or added to an existing plant.

FAQ

Frequently asked questions.

What is the difference between ERP and MES?

ERP manages business resources such as finance, purchasing and sales orders. MES manages execution on the shop floor. They exchange data: ERP sends orders down; MES reports progress, consumption and quality back.

What is a good OEE?

It varies by industry and process. Rather than chasing a headline number, use OEE to find and remove the largest losses on each line.

Can the software connect to my existing machines?

Often yes, through PLCs, sensors and standard industrial interfaces. Share your equipment list and we will assess it.
