A University of Excellence under the German Universities Excellence Initiative, TUM is consistently ranked among the leading universities in the European Union. It proposes 14 courses on EDX and 2 programs.
Why I took the course
Introduced by American engineer Bill Smith in 1986, Six Sigma (6σ) is a combination of tools and techniques for process improvement. When a process has an implementation of six sigma, it will produce 99.99966% free of defects for a given feature. This can be achieved by removing the causes of defects and minimizing variability, using empirical and statistical methods.
While my studies were in physics, I am nowadays leading the production department of my company and wanted to get a better knowledge of the field. That is why I started the course, to be followed by the recommended courses of Six Sigma: Analyze, Improve, Control and Lean Production.
The course starts introducing notions in the chapter and then clarifies them through more and more complex examples. The practice exams give you a very good indication of your grasp of the course.
The course chapters are the following:
Introduction to Six Sigma: The impact of defects and how to measure them
Understanding Customer Expectations: How to define what matters in your product and what to focus on first
Statistics Review: Statistic tools and understanding them
The Normal Distribution: A fundamental mathematical tool to calculate the key parameters of production processes
Process Mapping: Detecting the process that need improvements first
Measurement System Analysis: The description of measurement analysis, making the difference between precision & accuracy
Process Capability: Gives tools on evaluating the ability if a process to produce with satisfying quality
Quality Topics and Course Summary: Failure mode and effect analysis
Each chapter is concluded by a graded homework. The recommended five hours a week is a reasonable time to invest to be able to pass the homework successfully. Chapter 2 & 3 have additional homework where you are evaluated by other students and have to evaluate them. The idea is nice, but the execution success depends on each student’s participation.
How to succeed
My final grade is 91%, for a passing grade at 70%. Except for two exams where I made one mistake, all the others were fulfilled perfectly, except for the first peer-graded exam where I had a low score. Thankfully, deadlines can be postponed, which is very convenient when you are working. For the exams, I wrote some Python scripts to quickly do the calculations. A good grasp of statistics is definitely useful to succeed.
First I served in the Navy before completing a Master of Science in the field of nuclear fusion, followed by a Master of Science in nuclear fission. After that, I did a national graduate program at ESA before working in my current company where I was quickly promoted as head of production.
