We empower SMEs to boost performance and efficiency by bringing for the first time the proven Lean tools of large corporations within your reach
Our Founder
Teamcel was founded by François Chamoreau, an operational excellence expert with more than 15 years of hands-on experience transforming organizations across manufacturing, industrial services, and operations-driven environments.
Having working with large organization like FTSE 100, he saw first-hand what worked and what consistently failed. Rather than applying more pressure or more theory, François chose a different path:
Designing a system that blends structure, culture, and engagement into one coherent operating model DRIVES™
Today, François leads Teamcel with a clear conviction:
Sustainable performance comes from people who understand, own, and improve their processes.
Teamcel is supported by a growing ecosystem of practitioners, coaches, and partners who share the same vision: practical excellence, built with teams by teams.
Our Why:
In an uncertain global context, SME leaders are forced to operate under constant pressure every single day: fragile cash flow, rising costs, volatile raw material prices, talent shortages, and intense international competition.
Teamcel exists because we believe this situation is not inevitable for SMEs.
Simple to deploy and immediately operational, our conviction is clear:
Engaged teams
Consistent quality that builds customer trust
Performance that releases cash to reinvest and sustain long-term growth.
The challenges SMEs face today are not new. Global leaders such as Toyota, General Electric, and Amazon transformed similar uncertainty into strength by using Lean to eliminate waste, reduce costs, and accelerate execution. Their common thread was not size, but discipline.
Lean remains the most powerful strategic lever for SMEs: every waste removed, every delay eliminated, and every process stabilized directly protects margins and restores financial freedom.

The 6 Mindsets That Separate Winning SMEs From the Rest

Start From Customer Value & Clear Purpose
Operational Excellence is pointless if it doesn’t create value for the customer and support the company’s purpose. Lean and Lean Six Sigma both put “customer value” as principle #1: define what customers truly pay for, then remove everything else (waste).
Good OpEx firms help clients clarify why they exist, who they serve, and what “good” looks like in terms of quality, lead time, reliability and experience. Operational excellence starts from a clear purpose and strategy that’s understood by everyone, then translated into behaviors and systems.
Think in Systems, Not Silos
Most operational pain comes from local fixes that break something else. Serious OpEx work is end-to-end: map the value stream, see how work really flows, and treat the organization as a system, not isolated departments.
The Lean principles “map the value stream” and “create flow” sit exactly in this space.
Operating model frameworks emphasize that real excellence happens when processes, management systems, structure, and capabilities all line up and work in harmony – not when one area is optimized in isolation.
Respect & Develop People - Culture Before Tools
Every serious source on OpEx makes the same point: tools and methods only stick if the culture supports them. Ideal Results require Ideal Behaviors.
Lean is “much more than a toolkit”, it’s a management and leadership system that changes daily behaviors. An OpEx firm that doesn’t know how to build trust, psychological safety, and skills on the shop floor will never deliver sustainable change.
Manage by Facts, Make Problems Visible
Operational excellence is brutally honest. It means making performance visible and deciding based on facts, not opinions. Make systematic decisions based on data; with visual management, standard work and problem-solving routines.
You need a management system that continuously surfaces problems, connects them to KPIs and strategy, and reinforces the right behaviors. A good OpEx firm teaches clients to see reality clearly: where is time lost, where does quality fail, where is work stuck, and what does that mean for margin and risk.
Align Strategy, Governance & Daily Improvement
A common failure mode: lots of small “improvements” that don’t move the business. Strong OpEx firms make sure improvement is strategically aligned – every kaizen, every project, every routine is tied to a few key objectives (profitability, cash, customer experience, resilience etc...).
Craft a clear purpose and strategy, articulate principles and behaviors, then build a management system that reinforces them day after day.
Continuous Improvement as a Way of Life - Technology as an Accelerator, Not a Crutch
Every framework ends in the same place: never stop improving. One of Lean’s principle is “seek perfection”; also called continuous improvement. Look for a culture where everyone is engaged in small and significant change, every day.
Modern OpEx adds another layer: use technology (Industry 4.0, analytics, automation) to augment people and processes, not just bolt tools on top of bad systems. Why? Because tech only pays off when the underlying Lean/OpEx principles and behaviors are already in place.
