When I was a salesman, I used to have running battles with marketing. Then I became a sales manager and gosh, the battles only increased. Basically, I never had any faith in the so called “sales-leads” the marketing department sent down to us.
And, when I moved to marketing, I saw the other side. I saw the enormous amount of work we were doing to communicate to prospects and funneling the responses to sales only to have sales throw them into the trash.
