Service Management: An Integrated Approach to Supply Chain Management and Operations (FT Press Operations Management)

Easy to understand, light to read, and lots of good content. I had to buy this for a class text but now I use it as a reference.

It was free. These kind of materials for study are always welcomed. You will never know when you might need them. I do usually look at the reviews before I get them even if they are free. Sometimes they are free for a reason :)>
