Nigeria emerged from colonial rule with little technological know-how. This attributed to the fact that the colonial masters made no attempt at laying foundation for acquisition of the know-how required to build the economy. Despite this, the Nigerian economy has greatly evolved and is now termed the fastest growing economy in Africa. This is due the fact that they have developed skills and procedures so that businesses and organizations can prosper. Inn relation to banks, before the 2005 consolidation exercise so many individual had little or no faith at all in these financial institutions as some kept on folding out. How ever the consolidation process endorsed by the Central Bank of Nigeria was see and considered a savior to the economy. The banks later developed schemes and strategies to grow and face their competitors without crumbling; one of such schemes being the thorough function of the internal auditing department. This research reviews the roles and functions played by the internal audit department in organizations. It is therefore unavoidable to talk of the role of the internal audit department without relating to the views of the staff who work in such a department in any organization. Three firms in the same industry (the banking industry were thus selected) and questionnaires were issued to the members of staff working in this department. This project therefore focused on the importance of the existence of an Internal Auditing Department in any organization. It high lights some problems faced by banks and how the IAD could assist them in combating these problems
Chapter three dwelt on the research methodology employed in the study. I discussed the various sources data used, the sample from which information was sought and the reasonability of using such samples. Chapter four provide presentation and analysis of data collected and testing of research hypothesis. Finally Chapter five summarized the findings of the research and offers recommendations and conclusion.
