Introduction
There is no doubt that the pace of business change has increased and will continue to do so. It is also true that opportunities for significant incremental business benefit are diminishing and that, increasingly, organisations are depending on technology to achieve the much coveted but rarely accomplished step change in performance. Today in many public sector organizations, the use of IT has become important in enabling public services delivery. This has caused a critical dependency on IT that call a specific focus on effective IT governance. Accordingly, the success factors for governance over IT resources must be established and adhered to if an organization has to increase the contribution of IT in achieving its objectives. Several researches have been done on such IT governance effectiveness and necessary success factors but with no focus on such organizations in a developing country like Tanzania (environment). Several frameworks for IT governance exist with various approaches. These include control frameworks such as COBIT, and IT service management such as ITIL
The growing importance of information technology (IT) as a strategic factor for organisations in achieving their objectives, have raised the concern of organisations in establishing and implementing effective IT governance. The phenomenon is not only happened in private sectors but also in public sectors.this study is going to look at challenges and success factors affecting IT governance in the public sector. While there are various definitions of IT governance (Simonsson and Johnson, 2005), one of the most prevalent is that IT governance is an integral part of enterprise governance and has potential to provide mechanisms for leadership and organizational structures and processes that ensure the organization's IT sustains and extends the organization's strategies and objectives (ITGI, 2003).
