Six Sigma: Analyze, Improve, Control

Technische Universität München (Technical University of Munich) via edX


Learn how to statistically analyze data with the Six Sigma methodology using inferential statistical techniques to determine confidence intervals and to test hypotheses based on sample data. You will also review cause and effect techniques for root cause analysis.

You will learn how to perform correlation and regression analyses in order to confirm the root cause and understand how to improve your process and plan designed experiments.

You will learn how to implement statistical process control using control charts and quality management tools, including the 8 Disciplines and the 5 Whys to reduce risk and manage process deviations.

To complement the lectures, learners are provided with interactive exercises, which allow learners to see the statistics "in action." Learners then master statistical concepts by completing practice problems. These are then reinforced using interactive case studies, which illustrate the application of the statistics in quality improvement situations.

Upon successful completion of this program, learners will earn the TUM Lean and Six Sigma Yellow Belt certification, confirming mastery of Lean Six Sigma fundamentals to a Green Belt level. The material is based on the American Society for Quality ( Body of Knowledge up to a Green Belt Level. The Professional Certificate is designed as preparation for a Lean Six Sigma Green Belt exam.


Week 1: ANALYZE - Root Cause Analysis
Introduction to methods for root cause analysis, including Cause and Effect (Fishbone diagrams) and Pareto Charts. We learn how to perform statistical correlations and regression analyses.

Week 2: ANALYZE - Inferential Statistics
Learn the inferential statistics techniques of confidence intervals and hypothesis testing in order to use sample data and draw conclusions about or process centering.

Week 3: IMPROVE - Design of Experiments
Plan designed experiments and calculate the main and interaction effects.

Week 4: MEASURE - Analysis of Variance
Review how to perform a one-way Analysis of Variance (ANOVA) for comparing the between-factor variation to the within-factor variation for a single factor experiment.
Use a two-way ANOVA for testing the significance of the factor effects for a 2x2 DOE.

Week 5: CONTROL - SPC and Control Charts
Implement Statistical Process Control (SPC) & Control Chart Theory for monitoring process data and distinguishing between common cause variation and assignable cause variation. Construct X-bar and R Charts by calculating the upper and lower control limits and the centerline.

Week 6: CONTROL - Other Control Charts
Understand other control charts, including p-and c-charts and I/MR, and EWMA Charts and review of the Control and Response Plan for Six Sigma projects.

Week 7: Quality Tools: FMEA, 8D, 5 Whys
Use several important tools used in quality management, including the 8 Disciplines (8D) and 5 Whys, and learn the concept behind Design for Six Sigma (DFSS).

Week 8: Six Sigma Scenario and Course Summary
Step through a full Six Sigma scenario, covering all phases of the DMAIC process improvement cycle.

    I enjoy all three classes offered for lean six sigma yellow belt certification. The classes were short but effective. Step by step we learned DMAIC, lean methologies as well as all relevant statistical analysis. Dr. Holly Ott made the classes enjoyable by stimulating thinking via asking some key questions, providing relevant examples and really spending the time showing problem solutions. Invited speakers also added value providing different view some relevant to their industrial experience utilizing these techniques. I highly recommend this course and the series offered for LSSYB. Worth your money and time. Regards, zehra

    A very interesting introduction to the AIC-phase with RCA, DOE, ANOVA, SPC and control charts. Together with the other two courses of the professional certificate, this gives a good introduction to Lean Six Sigma for the beginner. The course material it thorough enough to be directly applicable, but avoids the gritty details.

    I have now and again come in contact with Lean and Six Sigma for over a decade and finally decided to get a more coherent overview. This course and the other courses of the professional certificate make a good start.

    It has been a very interesting course. Lessons are well-structure and very completed to know how to apply DMAIC for processes. Although I have worked as a quality engineer, I never used some of the tools here explained (it depends on how updated/lean the industrial sector is). So, I am completely satisfied with this course and indeed, I will make use of this methodology to work through lean sig sigma from now on. Also thanks to Pr. Holly Ott from her great explanations and preparation of the lessons. Olga Campo. Spain

    I find this course and the Six Sigma and Lean: Quantitative Tools for Quality and Productivity program as one of the best I've ever participated in. I highly recommend to anyone who would like to start the Lean Six Sigma journey. Once program completed, the Green Belt certyficate is in hand coverage.

    Thank you Holly Claudia Ott, Technical University Munich and edX.

    Prof Holly,

    I am happy to inform you that I have now passed the Green Belt certification of ASQ . Waiting for the certificate to arrive.

    Even though my experience span over 27 yrs in the industry, I could not formally get educated in the Six Sigma BOK. Your course helped me a lot in this regard. Many thanks to you , Prof Zubair and to your entire team of this course.

    Thank You once again

    This course has really helped a little boost in my professional career but also at personal level. The Process Improvement strategies and Management will help me to spot the possible problems or solutions to existing problems. It has also taught me to make a process map for Project Management, how to gather a team and the 5 Whys for the finding the source of the problems.
