Are you new to eCommerce? Thinking about setting up a team to support your companies web presence? If so, you might want to check out the IBM Redbook: Best Practices and Tools for Creating WebSphere Commerce Sites.
While the book focuses on WebSphere Commerce, it also has a lot of great best practices around commerce in general. From deployment to team setup, the book is pretty comprehensive and promotes general project management using the Rational® Unified Process or RUP®.
Another great chapter in the book is the messaging chapter. This is critical for any commerce project because you will most likely be integrating with existing systems like SAP or Bazaar Voice. Chapter 10 outlines the messaging architecture and shows how integration with these other system is achieved with WebSphere MQ.
