Six Sigma: Analyze, Improve, Control

Technische Universität München (Technical University of Munich) via edX


  • The current course run ends on June 30, 2021. If you think you won't have enough time to finish, you can enroll in the run starting on May 01, 2021 and ending on June 30, 2022 *

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.

    This course is follow up of the first part "Six- Sigma: Define and measure". The course is created such that it is easy to understand with several examples from real world problems. This part helped me in the field of analyzing, improving, and controlling CTQ variables to the success of the project. Although the topics covered were great but certain topics could have been elaborate and detailed. Other than that it is perfect.

    I hope to implement what I have learnt through this coursework at my place of work. And I would like to express my gratitude towards Holly Ott and the entire team of TUM for developing this coursework. Thanks and Regards.

    A great learning experience

    This course is well prepared to cover the topics of six sigma upto a green belt level. For me this course was perfectly made for both beginners as well as for professional who already know about six sigma. The classes were of top-notch quality and the instructors especially Ms Holly Ott was so good in explaining the topics and keeping the learning experience as effective as possible. This course is one of the best courses I've enrolled till now and I recommend this to anyone who's looking in to enter the field of Quality Management and other related fields
