From siloed behavior to data-sharing and collaboration across disciplines -- that's the journey that companies are making today, as they pass through the five stages of logistics maturity, according to Greg Aimi, director of supply chain research with Gartner.

Companies typically spread supply chain costs evenly across customers and products, but that results in some products and services subsidizing others, says Stan Aronow, director of supply chain research at Gartner. Aronow explains how cost-to-serve modeling can provide insights that lead to smarter and more profitable operating decisions.
