After this course you can
By the end you will be able to:
- Choose and charter projects with a benefit in cost units
- Run t-tests, chi-square and rank-based tests with sample size
- Fit ANOVA and regression models and check the residuals
- Plan and analyse full and fractional factorial experiments
- Write a control plan and coach Green Belts
Who it is for, and what you need first
Who it is for
Quality, process and manufacturing engineers, Green Belts moving up and improvement leads who run larger Lean Six Sigma projects.
Level: Advanced. Advanced. Assumes the Green Belt toolkit (DMAIC, process maps, basic charts, Gage R&R and capability), school algebra and a first look at statistics. Take Six Sigma Green Belt Training for Manufacturing first if these are new to you.
What you need
Software: A spreadsheet (Microsoft Excel or the free LibreOffice Calc) is enough for every worked problem in the notes. JASP (free, open source) or R give the full ANOVA, regression and designed-experiment outputs. Minitab is shown in a few lessons and is optional: Minitab offers a free trial on its own website (checked 1 November 2026), so read its current terms there..
Hardware: None. A computer that runs a spreadsheet.. What to download, and how.

What you practise
Course project, about 12 hours
Housing scrap at a moulding plant: ranking, charter, chi-square, 2 cubed experiment and control plan
Run a Black Belt project on scrap at a plastic housing line. Rank the candidate projects, write the charter with a benefit in cost units, test whether defects depend on shift, analyse a replicated three-factor experiment and finish with a control plan and chart limits. You deliver a charter, a test record, an effects table, chart limits and a control plan.

Common questions
What is the Lean Six Sigma Black Belt course?
It is a free-to-learn course that takes the Green Belt toolkit further: project selection and charters, hypothesis testing with power, ANOVA, regression, designed experiments, Lean flow and pull, control plans, change leadership and a full DMAIC case. Lessons are curated YouTube videos with EDWartens notes, worked problems, practice and an optional project.
Who is this Black Belt course for?
Quality, process and manufacturing engineers, Green Belts moving up and improvement leads. You should know the Green Belt basics: DMAIC, process maps, basic charts, Gage R&R and capability. Take Six Sigma Green Belt Training for Manufacturing first if they are new.
Will this make me a certified Black Belt?
No. The course covers the Black Belt body of knowledge and prepares you for Black Belt exams of the ASQ CSSBB or IASSC type, but it is not a Black Belt certification and not an ASQ or IASSC credential. Check each body's current exam page for its rules, because those exams may ask for project experience.
Do I need Minitab?
No. Every worked problem in the notes runs in a spreadsheet such as Excel or the free LibreOffice Calc, and JASP or R give the fuller outputs for free. Minitab appears in a few videos and is optional. It offers a free trial on its own website, so read its current terms there.
What statistics do I need to start?
School algebra and the Green Belt statistics: means, standard deviations, a basic hypothesis test and a control chart. The course rebuilds each Black Belt idea from data printed in the notes, so you can repeat every number yourself.
How long does the course take, and is it free?
About 14.7 hours of video and around 18 hours in total with the notes, worked problems and practice tasks, at your own pace. Every module, the notes, the optional project and the final assessment are free to learn.
What certificate does the Lean Six Sigma Black Belt course give?
A verifiable certificate of completion, issued when you finish the modules and pass the 15-question final at 60 percent. It has a unique certificate number, a QR code and a public verification page that shows the course, the modules covered and your final score.
Is Black Belt knowledge useful in quality jobs?
Employers in manufacturing, logistics and services list Black Belt skills for process improvement, quality and operational excellence roles. The course supports that knowledge with worked statistics and a project, but it does not promise a job or a result.
