Who We Are

Value-Added Management Advice, on the Floor

ACI is a consultancy for continuous improvement and operational excellence. Since 1997 we’ve supported organisations to reduce cost, eliminate waste and increase value for customers using lean management, lean manufacturing, 6 Sigma, QRM and TPM. In short: value-added management advice, delivered where the work happens.

What sets us apart is that every coach brings at least 15 years of hands-on experience in their domain. That’s why our approach makes performance improvements of 15 to 70% possible not on a slide, but on your line.

We work across every sector distribution, assembly, pharma, chemistry, food, metal, telecommunications and government always building a solution tailored to your organisation, whatever its size.

Why ACI

Method First, Technology Second

Plenty of companies will sell you a box. We start with the loss you’re trying to remove, then bring in the tool XL, OEE IntelliSuite or none at all only where it genuinely helps.

Method first

We lead with proven improvement methods, not a product catalogue the technology serves the method, never the other way round.

Coaching, not just installing

We stay beside your team supervisors and operators so new tools actually change how the floor runs and the gains stick.

Results that last

Our focus is measurable outcomes SQDCP, daily improvement, real OEE gains not a report that gathers dust after we leave.

Local & senior

European-based, Dutch/French/English, on EU time and every engagement is led by senior people, not juniors learning on your line.

The right technology

OEE baseline measurement
Dierik Rotsaert
Dierik RotsaertJun 30, 2026

Most manufacturers want to improve OEE. But before you improve, you need to know your real baseline. After measuring with XL, the real picture appears: short stops, changeovers varying, speed losses — these cost money every shift.

Production floor discussion
Dierik Rotsaert
Dierik RotsaertJun 16, 2026

In sommige fabrieken duurt de discussie over de oplossing langer dan het oplossen van het probleem. Op de werkvloer wil men vooral weten: Waarom ligt de lijn stil? Wat verliezen we vandaag? Wat kunnen we nu verbeteren?

Plant manager shopfloor
Dierik Rotsaert
Dierik RotsaertJun 12, 2026

A plant manager should understand within ten seconds what a production system can do for the shopfloor. Not after a long software project. Not after months of configuration. Start simple. Prove the value. Scale when ready.

Production line comparison
Dierik Rotsaert
Dierik RotsaertJun 4, 2026

Two production lines can both show 95% availability and still perform very differently. The difference is reliability. Frequent micro-stops disrupt the flow, reduce output and often lead to more scrap, rework and frustration.

Visual management data
Dierik Rotsaert
Dierik RotsaertMay 21, 2026

Many companies do not lack data. They lack clear, real-time information that people can actually use. That is exactly where XL creates value. Data alone changes nothing. Information x Decision x Action = Result.

Dierik RotsaertMay 12, 2026

Hoe goed ziet u wat er echt gebeurt op uw productielijn? Veel productiebedrijven verliezen capaciteit door stilstanden, snelheidsverlies, omstellingen of kleine onderbrekingen. Vorne XL maakt productieprestaties real-time zichtbaar.

Confession from a factory visit last week. “Are we doing well today?” The supervisor checks his laptop. “Hmm… yesterday we were.” That is why we introduced the new XL platform devices for 2026.
