I bought this textbook for a college course I was taking. I was excited because I wanted to learn about this subject however, I was disappointed once I realized how heavy in manufacturing this textbook is based and how little it talks about the service industry. I also felt that for a textbook it did not go into enough detail in some areas and seemed to gloss over service industry topics. It isn't a bad textbook though; I just find little use of it since I work primarily in the service industry and not manufacturing. I have to admit that my review is biased based on that reason alone.
