The Course is very useful with lots of operational improvement concepts. The difficult part is problem solving, it is too numerical in nature. Overall experience is good.
I understand that if you're reading this, it's probably already too late, but if not, I'd strongly advise that you research better opportunities to learn this material.
First, the presentation is poor. This feels like it would be a state of the art course in 2007, but is very archaic now. The powerpoints are sloppy, there's no editorial oversight, the audio quality is very bad, and it is harder to focus than it needs to be. They need the instructor from the Corporate Finance course to come in here and teach this team how to make a powerpoint that's legible.
Second, which is a problem I've had with other Coursera Wharton products, is the disconnect between the lectures, the practice, and the assignments. Things are left out or left to your own intuition, and you're on your own. The discussion forums are a great idea, but are totally neutered by the Coursera Honor Code which forbids students from discussing the assignments in any real detail. The Mentors are largely useless due to this limitation. This course should take note from the Financial Accounting course, which was similar in difficulty but worked you through every step of every possible problem type, and met you with challenging but doable assignments.
Third, is basic quality control. There are typos, self-contradicting statements, etc., that have remained unfixed in this material over the course of years (lectures are six years old I've gleaned). I'm astounded that Wharton is willing to put its brand name on a packaged product of this quality. Ironically enough, you're often sitting through a lecture about process integrity and quality assurance-related topics.
In sum, my experience in this course was mainly fighting against the class itself, not the material. Trying to figure out what the question means, what it's asking, rather than doing the math or remembering whatever function or logical process. It's really disappointing to have spent all this time on this course and the Business Foundations certificate program, when the utility per hour is so very very low. A complete rework is in order, if for no other reason than to get the instructor a new mic and have some grad assistant put together a nice sharp powerpoint instead of forcing students to read chicken scratches (which don't remain on the slides, so you better take really fast notes!)
