### 你将学到什么

To identify process problems and perform a root cause analysis using cause and effect diagrams and then performing a regression analysis.

To analyse data using inferential statistical techniques, including confidence intervals and hypothesis testing.

To test and quantitatively assess the impact of different improvement options using a design of experiment.

To test for the significance of effects using an analysis of variacne.

To implement control mechanisms for long-term monitoring using control charts for both quantitative and qualitative measurements.

To apply the Six Sigma methodology for the Analyse, Improve and Control phases in your work or research.

### 课程概况

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 Failure Modes and Effects Analysis 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 the 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 Yellow Belt level. The material is based on the American Society of 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.

### 课程大纲

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 one-way Analysis of Variance (ANOVA) forcomparing the between-factor variaion to the within-factor variaion for a single factor experiment.

Use atwo-wayANOVA for testing the significance of the factor effects for a 2x2 DOE.

Week 5: CONTROL - SPC and Control Charts

ImplementStatistical 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 center line.

Week 6: CONTROL - Other Control Charts

Understandother control charts, including p-and c-charts and I/MR, and EWMA Charts and review of the Control and Reponse Plan for Six Sigma projects.

Week 7: Quality Tools: FMEA, 8D, 5 Whys

Useseveral 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 afullSix Sigma scenario, covering all phases of the DMAIC process improvement cycle.

### 预备知识

This course reviews basic statistics used in Six Sigma and quality management, applying them to quality problems and methods. Therefore, basic math skills are necessary.

### 常见问题

Who offers this program?

The Professional Certificate ProgramSix Sigma and Lean: Quantitative Tools for Quality andProductivityis 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 sequentially, but it is not required that they be 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 theedX Professional Certificate for the programand theTUM 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 Certificateand the TUM Lean Six Sigma Yellow Belt certification.

The TUM LSSYB is based on the American Society of 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?

Anoverall average for all homework sets and peer-review assignments of 70% is required topass 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.
