Factors which may contribute to the growth of internal auditing in an organization are:

Use of computers for data processing tends to mean that individual security and supervision of transactions no longer occur. This means that a department is needed to ensure that continuing proper operation of other controls over transactions
Increased sophistication of management techniques requires more accurate management accounts and reports, this requires extra control over the accounting records which the internal audit department can ensure.
Management like the directors require an efficient internal audit department so as to help the external auditors to cut down on their works and so reduce the external audit fees
