Will the CFO and CMO ever form a more perfect union? I recently saw a study produced by Ernst & Young and reported in the Wall Street Journal that claims collaboration between CFOs and CMOs is increasing. The survey also acknowledges that there is still a long way to go to establish a real partnership between their responsibilities, particularly as it pertains to "common practices and cultural differences." In my opinion a perfect union is unlikely but a better working relationship is not only necessary but critical to the success of a business. Let's explore.
