I was wanting to go the same route but wanted to take a more management approach. I’ve got 2.5 years of corporate ID experience and started this past fall at Penn State in their Masters of Project Management degree. I looked at alot of options for MBA’s but what I noticed most about designers is few have much management experience other than what they have learned on the job. This program is basically an MBA degree with less focus on financial classes and more on team/people/project management concepts.
Also, the big motivation for me to go back was the fact that when most people see “designer” as a title, they automatically assume the person has no business ability because they are a designer. Although I still have basically the same poisition, I have changed my title during my last promotion to a more business sounding title in hopes that in the future, it will get a better look as I pursue higher design management roles.
