This document discusses several major IT frameworks: TOGAF for enterprise architecture, ITIL for IT service management, and COBIT for IT governance. It provides overviews of each framework, how they relate to each other, and how they can be used together. TOGAF provides guidance for developing enterprise architectures, ITIL provides guidance for designing IT service solutions, and COBIT provides guidance for governing IT and relating it to business goals. The frameworks can work together with TOGAF defining strategic architectures, ITIL defining detailed solution designs, and COBIT overseeing governance.
