Marketing and Sales can work Together to Develop and Execute a Profitable Business Strategy.
Yes, they can.
First though, we need to get past the centralised control v field operations barriers that exist.
This starts from having a open democratic company culture.
Do you have one?
If the culture is set by the business founder and distributed from a centralised temple, then it won't work.
You don't need a Moses coming down from Mount Sinai with the Ten Commandments.
Centralised control of marketing doesn't work any more. That's so last century, man. Come on, you can do better than that. Marketing and sales are bright people they need to come up with the ideas.
Take a look at how Zappos.com have developed their culture, from the bottom up. Not top down.
It's the staff who develop their culture, who work on it very day and deliver that to customers.
Consider having your marketing and sales own the business development strategy and delivering it to your market.
Let them create the plan. You don't need Moses.
And if you are Moses, remember he didn't make it to the Promised Land!
