No, I'm not being an enabler to the oft-heard "marketing sucks" claims from sales. Quite the opposite, in fact. I'm talking about marketing going on the offensive. I think about it this way: as a marketer, my job is to "sell" to the masses. Sales' job is to "market" to the individual (person, organization, whatever). We have the same job - our scope is just different.
Another example: marketing's job is to understand customer needs in the aggregate... a sales person's job is to understand individual customer's needs. We are both matching solutions to customers - the scope is just different.
You might argue that sales people also have to "close" (which wrongly implies that marketers don't). If you define "closing" as walking people through the buying process (like a realtor does), then I buy that. But if you accurately match customer needs to a solution offering, you don't have to pull out your bag of super secret "closes". The customers will close themselves.
