Sheila Chang completed this course, spending 2 hours a week on it and found the course difficulty to be very easy.
I have to agree with others, this course is very easy but it is the introduction for the specialization.
The big message here is "developing the right product, the done right and managed right".
I know that it seems easy but those are what make us crazy everyday. The message is simple, practicing is another story.
Of course, taking just any introductory course won't make anyone a product manager.
