OEE vs. ERP: A Guide to Building Your Manufacturing Software Stack

The Philosophy: "Manage the business of the business."

An ERP is a transactional system focused on the core business functions: finance, inventory (how many parts are in the warehouse), human resources, and high-level production planning. It's built to answer questions like, "What did we make last month?" and "What do we need to make next month?".

It is a "System of Record." It is slow by design, working with historical data and future plans, not the second-by-second reality of the factory floor.

The Philosophy: "Maximize the productivity of the factory floor."

An OEE system is a real-time, operational tool. It is laser-focused on diagnosing production losses by answering the questions: Are we running? How fast are we running? Are we making good parts?

It is a "System of Action." It is instantaneous by design, telling you that a machine just stopped or that its cycle time just slowed down, giving you the power to act immediately.

An ERP can't provide the real-time diagnosis. A standalone OEE tool can't provide the systematic cure. This is where the "missing layer" in the modern software stack comes in.

The Philosophy: "The diagnosis and the cure must be seamlessly integrated."

This platform is purpose-built for operational execution. It combines two critical functions:

1. The Real-Time OEE Diagnosis: To find and quantify problems on the factory floor.

2. The Integrated CMMS Cure: To manage the maintenance response that fixes those problems.

It is the essential bridge that connects the ERP's high-level plan to the real-world execution and problem-solving on the factory floor.

When you see the distinct roles of each system, the ideal software stack becomes clear.

The choice is not "ERP vs. OEE." The correct strategy is to use the right tool for the right job.

The modern, agile manufacturing software stack consists of two essential layers:

• ERP: For "Top-Floor" business planning.

• Integrated OEE + CMMS (like Fabrico): For "Shop-Floor" operational execution.

When you have both, your ERP can tell you what you need to make, and your integrated OEE+CMMS platform ensures you can actually make it as efficiently and profitably as possible.

Can my ERP calculate OEE?

An ERP can store OEE data after the fact, but it is not designed to collect it in real-time from your machines. This results in the same "history lesson" problem as using a spreadsheet, where the data is always too old to act on.

How do ERP and an OEE+CMMS platform integrate?

The most common integration involves sending a summary of the production data (e.g., total units produced, scrap count) from the OEE+CMMS platform to the ERP at the end of a shift. This gives the ERP the accurate, real-world data it needs to update inventory and financial records.

We're a smaller company; do we need both?

Most small to mid-sized manufacturers will get a much faster and higher ROI from implementing an integrated OEE + CMMS platform. It directly solves the most expensive problems (downtime, scrap, slow cycles). An ERP often comes later as the business scales.

Stop trying to use a financial planning tool to manage your real-time factory operations. An ERP is your rearview mirror, and you can't drive forward by only looking behind you.

Give your team the windshield they need to see and react to what's happening right now.
