Query: A classic book on PLM

I've only gotten through the beginning of the book but I can say that it is very well written, divided into many small chapters to help find any specific topic. It is written like a text book on PLM but a well written one. It defines PLM and puts it into historical business perspective and provides knowledge to implement a PLM project at a company. It is very long and thorough without many diagrams aside from several slides in the appendix.I will add more review once I complete the book but so far I have found that it contains straight forward, well organized insight into this field about which very little has been written so far. I would say this is a must read for any project manager planning to implement PLM.
