How to get marketing and sales to work together

It's no secret there's an inherent friction between the marketing and sales staffs at most companies. Borne of different personalties and shaped from different experiences, these two fields often fight like starved cats over a mouse.

But it doesn't have to be this way. I've posted an article on my website called "Cut bickering between sales and marketing with these tips"  Check it out.

Here are a few kernals from the article:

• Sales thinks in days; Marketing in years
• Marketing’s view is 30,000 feet; Sales’ is 3 feet
• Marketing must schedule ride-alongs with Sales
• Sales must let Marketing develop the messaging

What else needs to be accounted for between these two groups?
