What Is MES, and When You Do Not Need One

What a Manufacturing Execution System Does

An MES connects production activity with work orders, material records, and quality procedures. Its role extends beyond showing how many parts a machine has completed: it manages how work progresses through manufacturing.

For a buyer, the distinction is practical. Do you need to see production status, or do you need the system to assign work, track its progress, and manage production records? Write those requirements separately.

The 10 to 100 Machine Reality

This guide addresses factories with 10 to 100 machines. That range defines this guide’s audience; it is neither an MES purchase threshold nor a FactoryVision capacity claim.

Start with the questions your production team needs answered. Machine count alone does not define the software requirements.

When to Evaluate an MES

Evaluate MES systems when your requirements include:

• Assigning work orders to stations and tracking their progress.
• Recording materials and production history for traceability.
• Managing work instructions and quality records.

These are established MES functions described in IBM’s MES overview. Use your own workflow to specify which functions you need and how operators will use them.

List recipe management and machine-control requirements separately. Verify the functions and integrations of each system you evaluate.

When Production Tracking Is the Right Starting Point

Start by identifying the questions your factory needs answered:

• How many finished parts came off each machine today?
• Is each station on track, at risk, or behind its daily target?
• How much downtime has each machine recorded?

If these are the requirements, start with production tracking. Add work-order execution, traceability, and approval workflows to the specification when your process requires them.

FactoryVision serves factories that need finished-part counts, downtime tracking, and daily station status for countable, discrete parts.

MES vs. Production Tracking vs. ERP

The ERP description follows IBM’s ERP overview; the MES description follows IBM’s MES overview. Specify the functions you need and check them in the product you evaluate.

For the wider terminology, read our comparison of ERP, MES, OEE, SCADA, CMMS, and machine monitoring.

The Camera-Based Alternative for Discrete Parts

FactoryVision counts visible finished parts without wiring into the machine.

Core Capabilities

• **Count finished parts:** FactoryVision uses one camera per machine.
• **Track station progress:** It compares finished work with the day’s station target and shows one light per station: green on track, yellow at risk, red behind.
• **Track downtime:** FactoryVision tracks downtime.
• **Process locally:** Models run on a small computer in your factory, not in our cloud.
• **Teach a cycle:** Teaching a production cycle takes ten parts.

Operational Scope and Fit

FactoryVision fits countable, discrete parts that the camera can see. It runs in a Turkish door and furniture factory.

Continuous processes such as extrusion do not fit. The back of a part needs a second camera; shiny or transparent parts need lighting work.

FactoryVision is not an ERP, an MES, or a SCADA system. It provides finished-part counts, downtime tracking, and station status without wiring into the machine.
