Marketing Vs Sales: Who is More Important?

It’s time to quit the game of sales blaming marketing and vice versa when things don’t go right. It’s a dumb argument, and doesn’t accomplish anything. I have sat in far too many meetings and heard way too many mindless arguments about why “the other group” is not doing what they’re supposed to do.
In my new book A Mind For Sales, I focus one chapter on just this topic and more importantly about how I believe it should be handled.  To keep things simple, let me ask you a simple question before sharing my thoughts. The question is: who is going to know more about the customer – sales or marketing?  The answer is sales and for one simple reason: they’re the ones with the most one-on-one contact with customers. It’s sales that knows why the sale goes through and why it doesn’t.
