Marketing is about matching up the right message to the right market through the right media...

Sales is a marketing tactic. The salesman is the media, the sales pitch is the message, and the prospect is the market...

The pitch and process might be different, but thats because its a different form of marketing than print or tv or internet,etc...

But... your sales team should be under the umbrella of your marketing department... otherwise you will have the classic conflict of bad leads vs. bad salesman, a classic environment where people can easily shirk responsibility and shift blame instead of recognizing that they are all part of the same process.
