The 1 year MBA programs mentioned on the link by BB are pretty much the best 1-yr programs out there. You may also want to consider the fast track option of the Tepper MBA, which you can complete in 16 months, by forgoing the internship and doing your electives during the summer- however this option is best suited if you are not seeking a career change. Tepper would be a good fit for your IT+business career aspirations. They have a Technology Leadership MBA track that may interest you.
The Sloan MBA program i smore suited for people with more work exp - 10+ years.
Hope that helps.
