Organizations continue to make significant investments in Information Technology (IT) to enable business. To ensure a return on investment in IT, there is a need for a wider accountability focus on strategic technology initiatives alongside a structured and evaluative approach to the effective governance of IT. Throughout the last decade, systems, processes, standards and best practice frameworks have been developed to facilitate effective IT governance. However, IT deployment initiatives seem to fail to deliver outcomes This paper examines the impact of effective IT governance (ITG) on IT deployment. Literature review establishes the influencers (indicators) of effective ITG. A multiple case study analysis of failed IT deployment initiatives identifies key influencers (and indicators) of deployment failure. Finally, the outcome of the case study analysis is mapped back to the indicators of effective ITG derived from the literature review to determine a possible connection between failed IT deployment and ineffective IT governance.
