Lean Six Sigma Yellow Belt Online Course
You've seen what Lean Six Sigma is. Now it's time to actually use it. Yellow Belt takes you from awareness into real capability — DMAIC, process mapping, root cause tools and waste reduction, taught in plain English with live calculators you apply as you learn. By the end you won't just have a certificate. You'll know how to contribute to a real improvement project.
Yellow Belt
Recognised by the Council for Six Sigma Certification
SimplicityHub Lean Six Sigma courses are recognised by the Council for Six Sigma Certification as an accredited provider. You can view the accrediting body at sixsigmacouncil.org .
Built for first-time improvers
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.

Example Yellow Belt improvement projects
Yellow Belt training focuses on practical improvement work that can be delivered quickly within teams and departments. These projects are typically small, focused, and designed to build confidence in structured problem solving.
Reduce waiting time
Improve response time in a service desk, reception area, or internal approval process by identifying delays and standardising workflow steps.
Improve process accuracy
Reduce errors in data entry, order processing, or documentation by clarifying requirements, adding checks, and simplifying handoffs.
Streamline daily work
Remove unnecessary steps from routine activities such as reporting, scheduling, or stock handling to make work faster and easier.
Completing small improvement projects helps teams build confidence, demonstrate measurable results, and create momentum for wider continuous improvement activity. Yellow Belt learners often lead these initiatives alongside their normal responsibilities, making them highly practical and immediately useful in the workplace.
