Lean Six Sigma Institute

What Lean Six Sigma Institute does

Lean Six Sigma Institute is a privately held training and consulting firm founded in 1998 that delivers Lean Six Sigma methodology training and certification. The Institute combines Lean Manufacturing (originating from Toyota) with Six Sigma (originating from Motorola, AlliedSignal, and General Electric), teaching the DMAIC framework (Define, Measure, Analyze, Improve, Control), value stream mapping, statistical process control, design of experiments, and capability analysis. Its delivery is anchored by Master-Black-Belt consultants who hold both certification and prior operational business experience, and the firm structures engagements to transfer knowledge permanently to client employees rather than create long-term consultant dependency.

The Institute issues internationally recognized Belt certifications at three tiers — Yellow, Green, and Black — supported by a downloadable Black Belt resource library covering statistical tools, ABA/AOV, regression, DOE, and capability metrics. It serves organizations across industrial, service, and public-sector segments, with named historical client references including ITT Industries (a $435M profit improvement and 5x share-price growth attributed to Lean Six Sigma deployment starting in 2001). Operationally, the firm runs from offices in Brighton, UK (D16 Marine Gate, BN2 5TQ) and Paris, France (11-bis boulevard Delessert, 75016), employing 14 people, and conducting program delivery in both English and French.

The business model is high-touch, in-person or direct-engagement consulting and certification, with program pricing not publicly disclosed. Marketing is conducted primarily through the institute's website and free downloadable resources as a top-of-funnel content play, with bottom-of-funnel conversion driven by direct enquiry. Headcount, geographic footprint, and digital infrastructure have remained static over the 27-year operating history, indicating a lifestyle-scale consultancy rather than a growth-stage training platform. The firm holds no disclosed funding, no patents, no partnerships, and no executive leadership information beyond its founding Master-Black-Belt consultants.
