Do the Math.

Look at the curriculum for most Marketing MBA programs, and they’re loaded with math classes.  Which is interesting, because a failure to grow market share is almost never a math problem.  It’s almost always a branding issue — a failure to convince prospects that you’re the best choice, or to compel them to make the purchase.  The math matters, but in the end, it all comes down to presenting a unique brand in an appealing way that makes people want to act.  And that’s the bottom line.
