Tom,
I've also been walking the tightrope between the business and I.T. areas for many years. Like you, I've spent a good deal of my career as a business systems analyst, defining user requirements, preparing technical specs, etc. For the past four years, I've been managing projects, mostly implementations of packaged solutions. I don't particularly enjoy managing either, and it's especially difficult in a project setting, when the team is made up of employees from various areas of the organization.
I'm also tired of I.T. work in general and I'm looking to make a change. I've also considered Architecture and was willing to go back to school, but there are no part-time evening programs that I know of in my area and unfortunately I need to keep working full-time. I'm now applying to a part-time evening law school program.
I don't have any good advice for you other than what others have offered. Tailor your resume to each specific job that you're interested in and focus on the skills and competencies that they're looking for. I wish you the best of luck.
