What We Offer
Every engagement begins with rigorous diagnosis and ends with measurable, documented impact. We tailor each intervention to your industry, culture, and strategic goals.
A structured 2-day on-site engagement covering stakeholder interviews, process walk-throughs, and data gathering — culminating in a comprehensive diagnostic report and tailored project proposal.
Discuss your diagnostic →Remote and in-person Lean Six Sigma workshops at White, Yellow, and Green Belt levels — adapted for French business culture. Includes specialized IT tracks covering Agile, Lean, and DevOps alignment.
Enquire about training →A 6-week sprint targeting 1–2 high-impact, low-effort process failures. We deliver process mapping, root cause analysis, solution design, and KPI tracking — with visible ROI before the engagement ends.
Get a tailored proposal →An 8–12 week deep redesign of a significant operational process — incident lifecycle, dev pipeline, or customer support workflow — using value stream mapping, data analysis, and change management.
Get a tailored proposal →A 12+ week enterprise-level re-engineering programme spanning multiple departments. Includes advanced stakeholder management, benefits tracking, and embedding a continuous improvement culture.
Schedule a discovery call →Monthly or quarterly audit retainers for organisations that have completed an implementation programme. Includes Power BI dashboard reporting, KPI review, and continuous improvement coaching.

SNZ Sona Consulting France was founded by Somya Sethi and Naji Zenati with a single conviction: French organisations deserve Lean Six Sigma expertise that is both world-class in rigour and deeply adapted to local culture, regulation, and business context.
We operate on a hybrid delivery model — France-based consultants lead every client relationship, while a specialist offshore team in India and Bangkok provides data analysis, process documentation, and solution development at 40–60% below typical Big-4 rates.
Our target clients are IT managed services firms, software development houses, customer support operations, and manufacturing SMEs who need measurable results — not year-long engagements and generic frameworks.
If you can't describe what you are doing as a process, you don't know what you're doing.

Implementation, training, and knowledge transfer — with KPIs tracked and documented at every milestone.
Client Voices
"After the 2-day assessment, the team identified bottlenecks in our incident resolution workflow we had been living with for three years. The Quick Win engagement delivered a 34% reduction in average resolution time. The ROI was clear within the first month."
Laurent M.
Head of IT Operations, Managed Services Firm — Paris
"We were sceptical about an offshore delivery model, but the France-based lead gave us full confidence. Every deliverable was in French, every milestone was on schedule. Our QA pipeline is now genuinely Lean — and the cost was a fraction of what a Big-4 firm quoted us."
Claire B.
VP Engineering, SaaS Company — Lyon
"The Green Belt training workshop for our team was exceptional — practical, culturally attuned, and directly applicable to our customer support context. Our NPS score improved by 18 points in the quarter following the engagement."
Thomas R.
Director of Customer Success, Fintech — Bordeaux
Thought Leadership
Most manufacturers track direct waste. The indirect costs — rework, waiting, overprocessing — are what's actually destroying margins.
The right BI tool depends on your operational maturity. We analysed 23 client implementations to find the patterns.
Technology is rarely the problem. The gap between digital ambition and operational reality is where transformations collapse.
Get In Touch
Every engagement begins with a no-obligation 45-minute call to understand your operational challenges. From there, we design a diagnostic proposal tailored to your organisation — with transparent pricing and no hidden fees.
