Venables and Impey (1988:1) describe internal auditing as a function that
management has chosen to establish as part of the process of monitoring
performance to help achieve the operational targets and plans of the organisation. Independence of internal auditors means that auditors should be
independent of the activities they audit. An auditing function needs to be free
from interference in determining the scope
of its work, performing its duties and
communicating the results (ECIIA, 2005:28).
