Who it’s for
Who Should Study Lean Six Sigma?
Because every organisation has processes that could run better, Lean Six Sigma applies in almost any role or sector.
Operations & Process Staff
Anyone whose day-to-day work involves processes that could be faster, cheaper or more reliable.
Project & Programme Managers
Lean Six Sigma pairs perfectly with project management — the project delivers change, LSS makes the process it leaves behind perform.
Quality & Improvement Roles
The natural home for Lean Six Sigma — continuous improvement, quality assurance and operational excellence.
Managers & Team Leads
Lead improvement in your team, cut waste and make results more consistent with a structured, proven method.
Career Changers

Healthcare, Finance & Public Sector
Lean Six Sigma started in manufacturing but is now widely used across services, healthcare, finance and government.
What is Lean Six Sigma?
Lean Six Sigma joins two improvement approaches. Lean strips out waste and speeds processes up; Six Sigma reduces variation and defects so results are consistent. Put them together and you get a structured, data-led way to make work better — faster, cheaper and more reliable. It started in manufacturing but is now used across healthcare, finance, the public sector and services.
Yellow Belt or Green Belt?
Start with Yellow Belt if you’re new. It explains the principles and how you support improvement work as part of a team — useful for almost any role. Green Belt goes further into the DMAIC method (Define, Measure, Analyse, Improve, Control) and equips you to lead improvement projects yourself.
Why It’s Worth It
Lean Six Sigma is one of the few qualifications that applies in almost any sector, because every organisation has processes that could run better. It pairs especially well with project management — a project delivers the change, and Lean Six Sigma makes sure the process it leaves behind actually performs.
The Lean Six Sigma Belts Explained
Like martial arts, Lean Six Sigma uses coloured belts to show expertise: White (basic awareness), Yellow (supports improvement projects), Green (leads projects part-time), Black (leads projects full-time) and Master Black Belt (coaches others). We offer the two most in-demand levels for building a career — Yellow Belt to get started and Green Belt to lead improvement work.
What is DMAIC?
DMAIC is the backbone of a Lean Six Sigma project: Define the problem, Measure what’s happening now, Analyse the root causes, Improve the process, and Control it so the gains stick. Green Belt teaches you to run the full cycle yourself.
How Much Do Lean Six Sigma Courses Cost, and How Long Do They Take?
Both the Yellow Belt and Green Belt courses are £295, with payment plans available through Payl8r. Study is self-paced with 12 months’ access, so most learners fit it comfortably around work over a few weeks.
