APX: An Integrated Knowledge‐Based System to Support Audit Planning

Abstract

AbstractAuditors who must express an opinion on the financial statements of publicly held enterprises must perform a series of risk assessments as the basis for selecting appropriate audit procedures to be performed. Although many auditing expert systems have been developed for individual components of the audit risk assessment process such as inherent and control risk assessment, none integrate these assessments to arrive at the ultimate objective of assessing the allowable level of detection risk which drives audit procedure selection. This paper discusses critical design concerns for audit planning expert systems in light of the integrated nature of the steps involved in the audit planning process. The design and development of an integrated audit planning expert system called APX (Audit Planning eXpert) is also discussed. A distinguishing feature of APX is that it not only performs the individual types of risk assessments but it also integrates the resulting assessments to arrive at allowable detection risk. The knowledge acquisition and system development process are described to illustrate some of the mechanics of developing such a system.
