Course Syllabus

Lean Six Sigma Yellow Belt

Level: Yellow Belt | Price: £25 (or Free when you purchase the Ultimate DMAIC Playbook for £25) | Assessment: 40-question exam · 70% pass mark · Certificate + LinkedIn badge

Course Content

✓ DMAIC in full depth: deliverables, tools, and gate review criteria for each phase

✓ Project Charter: defining scope, problem statement, goal statement, team, and timeline

✓ SIPOC diagrams: mapping suppliers, inputs, process, outputs, and customers at a macro level

✓ Voice of the Customer (VoC): surveys, interviews, complaints analysis, and translating VOC into CTQs

✓ Process mapping: swim-lane maps, value-add analysis, and identifying quick wins vs. bigger projects

✓ Basic statistics: mean, median, mode, standard deviation, and what variation really means in a process

✓ Measurement System Analysis (MSA): gauge R&R basics and understanding measurement error

✓ Root cause analysis: fishbone diagrams, 5 Whys, interrelationship diagrams, and prioritisation matrices

✓ Basic hypothesis testing: understanding p-values and using data to confirm root causes

✓ Control plans and SPC: sustaining improvements with control charts, response plans, and handover documentation

Learning Outcomes

✓ Lead a scoped Yellow Belt improvement project from Define through to Control

✓ Write a project charter and get sponsorship sign-off from a line manager or director

✓ Run a VOC exercise and translate customer feedback into measurable project targets

✓ Map a process in detail, identify waste and variation, and prioritise improvement opportunities

✓ Collect and analyse basic process data to confirm problems and verify solutions

✓ Facilitate a root cause analysis session with a cross-functional team

✓ Build a control plan to hand over to the process owner after the project closes

✓ Present a completed improvement project to senior stakeholders with a clear before/after story

Estimated Annual Time Saving per Person

Estimated 10–20 hours per person per year. Yellow Belt projects consistently deliver 10–25% process time reductions and 15–30% error rate improvements in the areas targeted. A single completed Yellow Belt project typically saves 100–300 hours of team time annually, paying back the training investment many times over.

Learner Success Story

Do what Joe did.
Learn, apply, excel!

Joe Campbell took our Green Belt course, applied the templates to a real project, and turned it into a career-defining case study.

Joe Campbell

Lean Six Sigma Green Belt · Verified learner

★★★★★

“Really decent green belt course, using real templates and it’s great to work on a project, I would recommend!”

Joe didn’t just watch the lessons — he rolled up his sleeves and applied the DMAIC framework to a real workplace project. Using the course’s downloadable templates, he worked through each phase: defining the problem, measuring baseline performance, analysing root causes, implementing improvements, and establishing controls. The result? A documented case study that demonstrates real Green Belt capability.

Who is this for?

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 structured self-paced learning with guided tools and AI support, 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.

Real-world application

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.

Why these projects matter

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.
