I thought the same thing as I started reading through the article - this attitude is endemic to anyone who thinks that what they do is the most important function and that the business couldn't survive without them. The truth is that you need all parts of the business to succeed, working well together. That said, I think there are stages in the progression. In the beginning, you can't sell anything if you don't have a product. But once you have a reasonably good product, you need good marketing and sales to have people become aware of it. I worked closely with the marketing department in my last job and it definitely made me see how big an impact a good team can have. They did a lot of creative work to sell the product.
