Enterprise Architecture has become a rising area of interest for many
professionals in order to manage the technology portfolio of an enterprise.
TOGAF (The Open Group Architecture Framework) provides methods, models and
references to guide the design, implementation and evolution of business
capability by means of IT functionality. ITIL (Information Technology
Infrastructure Library) makes a similar promise from a different perspective
and has been the favourite reference for many IT service / solution provider
organizations with its unique focus to the IT service lifecycle. I tried to
reveal the unique characteristics, approaches, differences and highlights of
these frameworks in order to assist the readers to understand the use of these
frameworks, and guide the potential efforts for adaptation of any or both of
the frameworks in the enterprise environment.
