One of the reasons why Adam, Hugo and I wrote "Smarketing: How to Achieve Competitive Advantage through Blended Sales and Marketing" (available on Amazon) was so we could leave these articles behind.

Interesting read, but talks about sales and marketing working together in some sort of abstract and fluffy way.  In the book "Smarketing" we make sure we define a real path that companies (sales and marketing) can follow to gain the incremental revenue and competitive advantage gains mention.

While this article flaps around as a "why" you should do this the book "Smarketing" provides a "how".
