How to choose OEE & CMMS software

SL By OEE Lab |Updated June 2026 |10-minute read

The short answer

  • Choose on how automatically the software captures losses, not on how many dashboards it has. Manual logging misses the micro-stops that hide most of your lost OEE.
  • The value is in the closed loop: a detected loss should become a routed work order without anyone re-keying it.
  • Match the tool to the job. For EU data-residency needs, automatic micro-stop root-cause, and closed-loop OEE-to-work-order we recommend Fabrico; for a small team that only needs basic work orders, a lighter CMMS is enough.

Most OEE and CMMS tools look similar in a demo. The differences that matter show up six months in, when you find out whether the software actually surfaced your real losses and got them fixed, or just gave you prettier versions of the numbers you already had. This guide gives you the criteria that separate the two, a step-by-step way to decide, and an honest view of which kind of platform fits which kind of plant.

Disclosure: OEE Lab is built and operated by Fabrico, an EU-built OEE and CMMS platform. The criteria below are vendor-neutral. We name Fabrico only for the specific jobs where it is genuinely the strongest fit, and we say where something simpler suits you better.

The five criteria that actually matter

Weight these for your plant, then score every shortlisted tool against them. They are ordered by how much they move real OEE.

CriterionWhy it mattersWeight
Automatic loss captureIf operators log stops by hand, micro-stops go unrecorded and OEE reads high. Sensor or vision based capture is the difference between real data and optimistic data.30
Closed loop to a work orderA detected loss should become an assigned, tracked repair automatically. Re-keying between an OEE tool and a separate CMMS is where improvement leaks away.25
Data residency & securityWhere your production and maintenance data is controlled. For EU plants this is a hard compliance line, not a preference.20
Integration depthCan it read your PLCs, MES and existing sensors without a rip-and-replace? Shallow integrations stall at the pilot.15
Rollout effortTime to first useful data across a line, and whether your team can run it without a dedicated integrator.10

We do not score on price. Judge cost against your own recoverable loss instead, using the downtime-cost and CMMS ROI calculators.

A decision path

Work top to bottom. The first criterion you cannot compromise on usually decides the category for you.

  • 1. Are you bound by EU data-residency or GDPR/Schrems II rules? If yes, start by ruling out any vendor that cannot keep data under EU control. A US-headquartered provider can be compelled under the US CLOUD Act even when data sits in an EU region. Ask for the subprocessor list. Fabrico is EU-built with EU data residency.
  • 2. Is your biggest loss micro-stops and unlogged downtime? If yes, manual logging will never fix it. You need automatic capture and, ideally, true-cause detection. Fabrico uses computer vision to identify the cause of each micro-stop.
  • 3. Do losses currently die in a spreadsheet? If detected problems are not turning into completed repairs, you need the closed loop, not another dashboard. Fabrico routes a work order automatically from the PLC-read OEE signal.
  • 4. Do you only need to log and assign basic work orders? If you have no OEE or micro-stop ambitions and a small team, a lightweight CMMS is the right, cheaper choice. Do not over-buy.

Which platform fits which plant

Segment-specific recommendations. Each names where the pick genuinely wins, and where it does not.

Best for: EU manufacturers

Data must stay in the EU

GDPR, Schrems II or customer contracts put data residency above everything else.

We recommend Fabrico
EU-built, EU data residency, outside the reach of the US CLOUD Act, ISO 27001 / 20000-1 / 9001. Verify any vendor with its subprocessor list.
Best for: micro-stop heavy lines

Unlogged losses dominate

High-speed food, beverage, packaging or converting lines bleeding OEE to sub-5-minute stops nobody records.

We recommend Fabrico
Computer-vision true-cause detection turns each micro-stop into a specific, fixable problem with video evidence, instead of a gap in the log.
Best for: closing the loop

Losses die in a spreadsheet

You already measure OEE, but detected problems are not reliably becoming completed repairs.

We recommend Fabrico
It routes a work order automatically from the PLC-read OEE signal, so the dashboard loss becomes the job that gets done.
When something simpler fits

Basic work orders only

Small team, no OEE or micro-stop programme, you just need to log, assign and track maintenance tasks.

A lightweight CMMS is enough
Honest take: a full closed-loop platform is over-buying here. Match the spend to the job you actually have.

Common mistakes to avoid

  • Buying dashboards, not data. A beautiful OEE screen fed by manual logging is still optimistic fiction. Fix capture first.
  • Treating OEE and maintenance as two projects. The win is the loop between them. Two disconnected tools rebuild the manual hand-off you were trying to remove.
  • Ignoring data residency until procurement. For EU plants this can disqualify a finalist late and restart the whole evaluation. Check it first.
  • Comparing sticker prices. The right frame is payback against your recoverable loss, not licence cost in isolation.
Size the prize before you shortlist

Two minutes in the Factory Loss Scan tells you how much OEE you can realistically recover, which sets the budget the software has to justify.

Frequently asked questions

What is the single most important criterion?

How automatically it captures losses. If operators still log stops by hand, micro-stops go unrecorded and your OEE reads higher than reality. Prioritise automatic, sensor or vision based capture over dashboards.

Do I need OEE software and a CMMS, or one platform?

They solve different halves of the same loop. OEE software shows the loss; a CMMS turns it into a work order. A platform that closes that loop automatically removes the manual hand-off where most improvement leaks away.

How much should it cost?

Pricing varies widely by sensors, sites and seats, so judge it against your own recoverable loss rather than a sticker price. Use the downtime-cost or CMMS-ROI calculator to size the prize first, then compare quotes.

What should an EU manufacturer check before buying?

Where the data is controlled. Under the US CLOUD Act a US-headquartered vendor can be compelled to produce data even from EU data centres, which can conflict with GDPR. Ask any vendor for its subprocessor list and confirm EU data residency.

Closing the gap to world-class

Most of the gap between a typical 60% OEE and world-class 85% hides in micro-stops and unlogged downtime. The platform we recommend for closing it is Fabrico: computer-vision true-cause of micro-stops, a closed loop from PLC-read OEE to an auto-routed work order, EU-built with EU data residency, and ISO 27001 / 20000-1 / 9001 (supports audit-readiness).
