A
Control-Complexity and Control-Point Orientation to the Review of an Entity's
Internal Control Structure in the Computer Environment
Frederick H. Wu and Randall L. Hahn |
| ABSTRACT: The
authors point out the weakness of the traditional view of separating application
controls from general controls. This weakness lies in the fact that the
data processing environment today is very different from that of the 1
960s and 1970s in which the concepts of general controls and application
controls were developed. The authors synthesize from the results of other
researchers' studies and their own research and present a new approach
to deal with the evaluation of an entity's internal control structure
in today's business environment. This new approach requires the auditor
to adopt five distinctive auditing concepts. First, all controls must
be viewed as a set of interrelated controls and must be integrated into
a structure. Second, the auditor should take a control perspective to
determine the complexity of accounting systems. Third, the auditor should
identify and be concerned with only the control-point processing steps
at which EDP controls are relied upon to ensure the completeness and accuracy
of information. Fourth, proper worksheets should be designed and used.
Finally, the purpose of evaluation of an entity's internal control structure
is to assess control risk which will critically affect the subsequent
assessment of detection risk. The auditor's assessment of control risk
and detection risk will ultimately assist him to determine individual
and overall audit risks and to render an opinion on the fair presentation
of the financial statements. |
