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 (www.asq.org) Body of Knowledge up to a Green Belt Level. The Professional Certificate is designed as preparation for a Lean Six Sigma Green Belt exam.

# Syllabus

Skip Syllabus

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 did not have any prior knowledge of Quality Management but have always known the value, importance, and job demand related to this topic. I am very glad that i enrolled for this course, although i have to put little extra efforts and time to understand the material but i am very thankful to Dr. Holly Ott for her special teaching skills to explain every topic in a simple way and with practical examples. I also appreciate the guest speakers and their expertise in the subject. I plan to complete all the three courses of this certificate program as soon as i can. I am into my very first course and within couple of weeks i was motivated to look into CSSGB (Certified Six Sigma Green Belt), as I know CSSGB is going to be very useful for professional advancement. I believe if i understand these three Quality Management courses my foundation to study for CSSGB with be solid. My Humble Gratitude to the entire MOOC team and EdX team and many more who are behind the scene to provide us best education from the top most educational institutes.” --Asha Grover

"This is my second time around using statistics. In Define and Measure I was able to learn how to apply statistics to define problems in in factories and industries. And the ability to measure the results to start an improvement process. I love the instructors who lectured the course. They all have such a breadth of knowledge. My goal after completing this series is to get certified through ASQ to get my Green Belt. I feel confident that this series will lead to that goal.” --Previous student

“If you are new to Six Sigma like me, this course will greatly expand your skills and knowledge. The course includes many examples, practical exercises, real life case studies, and guest lecturers. These help to reinforce concepts, apply the math, and master the topics.” --David Rozene

“One of the best online course for 6 sigma. This course has helped me professionally as well as personally, whether taking a decision or solving a problem raised. Very well-articulated, elaborately explained with proper usage of tools and most importantly usage of formulae & examples for numerical problem solving. Discussion forum to share and learn from your peers and getting your doubts clearly by the staff, who promptly reply to every query posted. Thank you everyone who structured this course as is and my best wishes for your future endeavors.” --Murali Dhepalli

Who offers this program?
The Professional Certificate Program Six Sigma and Lean: Quantitative Tools for Quality and Productivity is offered by edX and the Technical University of Munich (TUM).

How many courses are in the program?
There are three courses in this program:
Course1 QPLS1x - Six Sigma: Define and Measure
Course2 QPLS2x - Six Sigma: Analyze, Improve, Control
Course3 QPLS3x - Lean Production

Do I need to take the courses in order?
The courses should be completed sequen tially, but it is not required that they are completed in any particular order. However, as Course2 QPLS2x - Six Sigma: Analyze, Improve, Control builds on the material in Course1 QPLS1x - Six Sigma: Define and Measure, we strongly recommend that you take QPLS1x before you take QPLS2x.

Which certification do I earn for this course?
You will earn the Verified Certificate forCourse2 QPLS2x - Six Sigma: Analyze, Improve, Control.

What certificates do I earn with this program?
Upon successful completion of this program, learners will earn both the edX Professional Certificate for the program and the TUM Lean Six Sigma Yellow Belt certification. In order to achieve the TUM Lean Six Sigma Yellow Belt Certification it is mandatory to complete all 3 courses in the program and achieve a Verified Certificate in each. Then, automatically, you will earn the edX Professional Certificate and the TUM Lean Six Sigma Yellow Belt certification.
The TUM LSSYB is based on the American Society for Quality (www.asq.org) Body of Knowledge up to a Green Belt Level. The Professional Certificate is designed as preparation for a Lean Six Sigma Green Belt exam.

What is the passing grade for the course?
An overall average for all homework sets and peer-review assignments of 70% is required to pass the course.

Do I need to achieve 70% on each homework?
No, you need an average grade for all homework sets and peer-review assignments of 70%. This means you can do poorly or miss a homework set as long as you do well enough on other homework sets to achieve 70% overall.

How do I receive the edX Professional Certificate for this program?
The Professional Certificate will be available from your dashboard after the end of the course.

How do I receive the TUM Lean SixSigma Yellow Belt Certification for this program?
If you have earned the Verified Certificate for all three courses in the program, then you will receive the edX Professional Certificate and the TUM Lean Six Sigma Yellow Belt. These will be sent to you by email.
-- For those finishing all courses by October 31, you will receive your certificate before November 31.
-- For those finishing all courses by February 28, you will receive your certificate before March 31.
-- For those finishing all courses by June 30, you will receive your certificate before July 31.

When you have passed all three courses with a verified certificate and received the edX Professional Certificate, you can also include in your CV that you have achieved the TUM Lean Six Sigma Yellow Belt, TUMLSSYB .
