The foundation course for anyone new to Lean Six Sigma. 4 modules, live calculators and plain-English explanations — built for team members, supervisors and first-time improvers.
Yellow Belt
If you work on a team that does continuous improvement but have never had formal training, Yellow Belt is built for you. You will come out able to identify waste, follow a DMAIC project as a team member, and use the basic tools — process maps, 5 Whys, fishbone diagrams, 5S.
Yellow Belt takes 2-3 weeks at about 3-4 hours per week. It is entirely self-paced, with quizzes at the end of every module and a final knowledge test. You get a personalised certificate when you pass.
It is also the cheapest, lowest-risk way to see if Lean Six Sigma is for you before committing to Green or Black Belt. If you want the full journey, the Suite bundle (Yellow + Green + Black for £315) saves you £275 versus buying separately.
What it is, where it came from, and why it saves companies millions. You'll finish able to explain it clearly to a colleague.
The five-phase improvement framework. How Yellow Belts support Green and Black Belts during real projects.
Spot the 8 wastes in your own workplace, with examples from offices, factories, hospitals and retail.
SIPOC, swimlane and value-stream maps — when to use each and how to draw them without specialist software.
5 Whys, fishbone diagrams and basic Pareto analysis — taught with real worked examples.
Sort, Set, Shine, Standardise, Sustain — applied to both physical and digital workplaces.
Team members, supervisors, customer service staff, and anyone who wants to understand Lean Six Sigma without running projects yet.
2-3 weeks at 3-4 hours per week. Fully self-paced.
No. Yellow Belt assumes zero background. We teach plain English first, jargon second.
Only if you already lead improvement projects. Most people find Yellow Belt is the right starting point — and the Suite bundle (£315) gives you all three belts at a huge discount.
Aligned with industry standards and mapped to the Lean Six Sigma Yellow Belt framework. Issued by SimplicityHub Academy on completion.
