In January 2009, Forrester released a 100-criteria evaluation of the top enterprise-class eCommerce platform vendors known as the Forrester Wave™. In anticipation of the 2010 business-to-consumer (B2C) eCommerce platform Wave, we wanted to take the opportunity to provide updates on the so-called "class of 2009" and the major developments tied to their product, road map, and strategy. Additionally, we wanted to provide an analysis of these changes to help multichannel and online retailers meet the needs of the online consumers in a dynamic and increasingly complex space.
