Our goal with this year's '100' is to highlight a broad range of innovations taking place in the theory and practice of supply chain transformation. Therefore, our judging committee will particularly be looking for solutions across a variety of industries, addressing the needs of companies of varying sizes, and assisting in the transformation of a diverse mix of the functions that make up the supply chain.

Mr. Costello has shown himself to be a clear thought leader in the spend management industry. His efforts in developing the tools and processes necessary for supply chain transformation, and in promoting new approaches to supply chain enablement, have helped companies around the world enhance their performance and advance their strategic goals.
