How We Calculated This
Methodology & Transparency
These projections are grounded in data from 47 SNZ Sona Consulting engagements completed across France and the EU between 2019–2025, cross-referenced with published Lean Six Sigma industry benchmarks from ASQ, IASSC, and McKinsey Global Institute research.
- — The 38% savings rate is a conservative median figure across waste-reduction engagements; individual results range from 22% to 61%.
- — Revenue midpoints are used for modelling; actual waste is calculated as a percentage of operating costs, approximated at 60–70% of revenue for most sectors.
- — The 8% compounding factor reflects efficiency gains that compound as process improvements become embedded in operations.
- — Engagement costs shown are indicative ranges. Final investment depends on scope, duration, and complexity of the engagement.
Disclaimer: Actual results depend on engagement scope, organisational readiness, and implementation quality. This calculator provides directional estimates only and does not constitute a guarantee of outcomes.
