This is the best book on the subject of analyzing expenses; in fact, it is the only book that covers this subject!
I have worked for over three years in spend analysis from a technical perspective, so when I found out that a book on the subject was finally published I decided to give it a try.
The pace was right, and smooth, because the authors anticipate a lot of the questions that a reader may have. The book covers both the business aspects and the technical aspects of conducting spend analysis. If you are a commodity manager, you should memorize chapters 4 and 7! If you are responsible for data warehousing , part II of this book is a must-read, even if you do not work on spend analysis or sourcing! If you are new to procurement, Part I of this book will introduce you to the subject of spend analysis and its value. If you are an experience procurement person you will find this book invaluable for its insight and depth.
The book is great for anyone who feels that they need to advance their skills in sourcing and, especially, strategic sourcing.
I've read short reports on spend analysis before (from Aberdeen, Gartner, etc.) but it never sank in. What's great about this book is that
the authors give very clear definitions of key terms and then they take you step-by-step through each topic and how it is reflected in the real world cases.
Despite the great breadth and depth of the book, it is not too long, it is succinct from start to finish. This allows you to go quickly through the entire book; but yet, if you read a couple of chapters a second time, like I did, you will be able to get even more out of the book the second time! That's awesome!
The book is a bit expensive for a technical person but its value is far greater than its price. It is an excellent book of enormous value and I highly recommend it.
