1.1 Introduction
Internal Auditing is an independent appraisal activity established within an organization as a service to it. It is a control which functions by examining and evaluating the adequacy and effectiveness of other controls.
It can also be defined as a control established within an organization, originally concerned with the financial records, investigative techniques developed by the control is now applied to the analysis of the effectiveness of all parts of an entity’s operation and management.
In any organization, the management usually sets out the plans including control procedures while the internal auditors supervise monitors and reviews as well as ensures compliance with such plans and control procedures.
However, large organizations are faced with various problems of co-ordination, control, public and employee relationship and general management. The development and maintenance of internal control system which is under the watchful eyes of internal audit staff is therefore of great important in this regard.
Internal control system can be defined as “a whole system of controls, financial and otherwise established by the management in order to carry on the business of the enterprise in an orderly and efficient manner, ensures adherence to management policies, safeguard completeness and accuracy of the record.
An internal Auditor must be free to review the whole internal control system of an organization. However, there is a sharp distinction between internal and external auditing.
The Auditing Practice Committee (APC) defined External Auditor’s duty as “Independent examination of and expression of opinion on the financial statement of an enterprise by an appointed auditor in the pursuance of that appointment and in compliance with any relevant statutory obligation. While an Internal Auditor’s duty is to prevent and detect errors and frauds by the management, the detection of frauds is only indicated in the case of external Auditors.
For an effective internal auditing program, the internal auditor must be independent; the independent of internal auditing department is to be responsible to an officer of sufficient rank in the organization to ensure a broad scope of activities and adequate consideration of an effective action on the findings and recommendations made by him. He should not develop and install procedures and prepare records which he would not be expected to review and appraise.
