This article is from ManageSmarter.com and it debunks 6 very common sales myths. My absolute favorite from the short article:
Myth: If sales understood the product better, sales would increase.
Reality: Actually, if everyone in the company—e.g., marketing, product developers, IT, and fulfillment, to name a few—understood sales better, sales would increase.
That reality is perfectly stated and true. Successful selling, or should I say unsuccessful selling, has more to do with sales technique than it does with product knowledge.
However, we have encountered many companies where the other departments felt they could direct the sales department. The common theme in those companies is that these departments believe they know sales better than the sales department!
