Are you an experienced professsional with aspirations to become a senior manager or an executive at a reputable company? Having an MBA degree along with technical degree would definitely help IF you meet other requirements. MBA alone will not help though. Also, it is better to emphasize on areas where you want your career to be. For instance, MBA with Financial Engineering might help with investment banking positions more than it might at standard IT jobs.

Comments or brainstorming sessions are welcome.

Hope this helps,
