ITIL adoption has started to wane over the last few years due to the overall cost of implementation and difficulties with integrating the ITIL methodology with the current corporate Information Technology (IT) strategic plan. This becomes even more apparent as IT departments move- away from the traditional service delivery models to private cloud sourcing strategies. The purpose of this research is to establish a roadmap, as part of the ITIL maturity plan, for the first phase of ITIL implementation for organizations moving towards these new service-sourcing models. This work provides IT organizational leaders with a methodical approach to ITIL implementation that supports a migration strategy to a private cloud sourcing model as part of their 3 to 5 year IT strategic plan. The initial phase of this research, which is detailed in this paper, is a comprehensive literature review with insight from ITIL practitioners and industry surveys. From this research, several conclusions are expected. The most valuable conclusion that can be drawn will be an established strategy for ITIL implementation that will ensure long term success for those seeking to use private cloud sourcing.
