"This book has quickly established itself as the essential reference book for category management and a practical guide for practitioners. With its thoroughness and insight, it is valuable to both the category novice and the experienced manager and should be on every senior procurement executive's bookshelf."

Peter Smith, Spend Matters

"O'Brien's ability to objectively re-evaluate his own authoritative perspective on category management - given the significant changes in procurement priorities and the widespread impact of digital technology - is impressive, and allows the reader to chart their future path from a more stategic position."

Kelly Barner, Owner, Buyers Meeting Point LLC

"This edition is a siginificant step forward. O'Brien's widely acclaimed and established exposition of category management is further complemented by rich new insight from leading practitioners into how organizations can realize an effective implemention of this approach. Another essential tool for the modern strategic procurement leader or practitioner from one of the leading authors in our community."
