I was disappointed that so much of the materials of the course are in the 'optional book'. I felt that I missed a lot of information because I did not have the book. Knowledge to answer some quiz questions was also not found in the videos, but probably only in the book. The videos are only short and concern mostly bullet points. It is a much slower way to absorb information than through reading. Buying the book would not be a problem, if it weren't for the fact that it is a relatively obscure book with only very few reviews. I would not trust it enough to use it for anything else but this course.

I also found that the transcripts of the videos often contained mistakes. One time, the transcript was not synchronized with the video and contained the text from when the lecturer made a mistake, including '[laughter]'. The speakers often failed to be engaging. Especially week 1 felt that way.

I would have preferred more text, accompanied by videos that contain more examples (week 4 contained a good example). An optional book is also okay, but I would prefer it to be a more mainstream book. One that I can continue to use after the course, and preferably even when doing a green belt course. The interview was also excellent material and helps greatly with remembering.

I am providing a rating for the entire Yellow Belt Specialization, which consists of four courses. This review covers the entire specialization, not just a single course. Compared to other, newer courses on Coursera, I would rate this specialization three stars. Often, the content feels like a blur of information. The instructors are only visible at the beginning, likely reading from a script. Some even pause awkwardly when turning to the next page. There is a lack of emphasis on key points, no examples to illustrate concepts, and no repetition to reinforce important information. Additionally, there is no summarizing at the end of the lessons. The slides presented are outdated and often irrelevant to the spoken content. From a didactic perspective, this course has significant room for improvement. However, the quality varies between instructors. I particularly liked Dr. Bailey and Dr. Scherrer, but the majority did not meet my expectations. Despite these issues, I completed the course and believe it provides a solid foundation. Compared to other Yellow Belt courses, which can be as short as a few hours, this specialization offers a more comprehensive basis for advancing to Green and Black Belt levels.

The information in the slides was only half of what you needed to successfully complete the quizzes. As stated in the intro video, the Certified Six Sigma Handbook (2nd Edition) should only serve as an optional additional source material, in order to better understand what is covered on the slides. Instead, half of the answers on the quizzes could only be attained if one has access to the book. This is a really cheap tactic to force students to buy additional source material, which is stated in the syllabus as not being mandatory to buy. As a result, I'm going to return the favor in kind by giving this course half the rating that it deserves.

Pros: A few great Sections. Nice to work at own pace.

Cons: Unbelievably focused on manufacturing. Service and Electric / Media products are ignored. Some sloppy slides. An unabashed ploy to sell more of the author's books. The ASQ (American Society of Quality) CSSGB manual would be a better choice. The sections on Brainstorming are a mess of contradictory and ineffective ideas. Change Management is completely ignored yet a crucial part of effective LSS. 1.5 sigma shift is so useless and poorly explained I cannot believe it was included. Tests do not focus on key take aways instead too much on minutia.

Las ayudas visuales y videos fueron apropiados y excelentes. ademas interesante el hecho de poder interactuar con tus compañeros calificando tareas.

No me gusto mucho que parte del curso requiera material externo pero no pueda ser proveído, si algunos compañeros no lo publican quedariamos varios sin información, por otro lado los instructores tienen muy poco que ver con los cursos, usualmente no resuelven la preguntas y hay poca interacción con ellos. deberían dar videos explicativos ya que muchos temas quedaron cortos en la explicación. por ejemplo en las explicaciones de partes por millon o la parte matemática

Poorly written course. Many incorrect statements such as 1000/9000 = 9 defects per unit. Also, the first part of the course states, "The companion text is not required to complete the assignments" and the companion text is the Sig Sigma Yellow Belt 2ed which is not even the latest edition so of course I am not going to buy it and the majority of the questions on the quizzes were NOT covered in the videos and associated transcripts which I feel is very disingenuous to say the book is not needed and then actually write the quizzes based primarily on the text.

While it is optional to purchase the book, I'd imagine it contains a lot of information needed for this course. The slides do not necessarily tell you enough for you to get 100% on the exams. The book used for this course is not available via e-reader. Therefore, if you were to use it, you'd have to wait until the book arrives at your doorstep.

The instructors are generally dry and read off a script, unlike some of the other courses I have taken where the instructor knows the material and is teaching it to you via pre-recorded video.

I enjoyed the practical aspects of this course. The tools and ideas which can be applied in a variety of work environments. I found the history of Six Sigma and the emphasis of certain men who developed the concepts less useful and would have preferred it was more condensed. The Handbook is expensive and not particularly well written, not the best value as compliment to this course. The presenters were okay, they conveyed the necessary information but it was done in a particularly bland and unengaging manner.

While the rest of the content is great, David Cook's sections are not good. In these sections the content on the slides is often unrelated to the content which makes either very hard to follow. There is also a strange focus on the history of these tools, irrelevant to most people, especially when presented in the meandering way done here. The quizzes in these sections are also terrible, mostly testing your ability to remember exactly how David Cook worded a sentence rather than anything applicable in practice.

The course was a nice experience, it was helped with the knowledge and it was productive. The only improvement i feel which is needed is the videos was not interactive at all, they were boring and was not helpful when it comes to focusing there. As the courses were not interactive and monotonous so it was taking much longer to complete one video than expected. Thank you Coursera team for this course and for providing me financial aid, it really makes a difference to this world. Thank you.

Even though this course is an introduction, it relies too heavily on sending the student to the Six Sigma Yellow Belt Handbook (which is not required for the course). The basic principles are covered, however an entire course based on power point slides is difficult to stay engaged in. It would be useful to add more video of the lecturer as well as visual aides. I was very concerned about one of the quizzes misspelling Mikel Harry's name.

The introductory course to Six Sigma Principles is useful in that it familiarizes the participant with the terms and overarching strategies of Six Sigma and its core components. Having taken this course, I believe that purchasing and reading the book for Yellow Belt certification would be a far better use of time unless the potential participant is an auditory learner or wishes to have a guided experience to accompany their reading.

I learned a lot, but this course could have been presented in a much better fashion. Many of the quiz questions were straight out of the book, despite the book being optional to the course. The presentation slides from the first week of the course were noticeably worse than the rest of the course, which I'm sure will deter some people from continuing.

The examples are not sufficient explained.

Sometimes the information taught in the course is not answering the questions in the tests but with a lot of reading and deduction, an answer can be made, so the time mentioned as the time needed is not realistic at all.

Lecture videos need a little "hype" there are to linear.

I hope this is constructive

There were a lot is mistakes on slides, errors in the transcipts (e.g. duplicating sentences), multiple occasions when content that was not covered in the online content was asked about in quizzes. I assume the questions came from content in the recommended reading. But if it's recommened and not required, it should not be tested on.
