These are the managerial problem solving methodology of Logistics Information System auditing and the structured development of expert system technology. The investment being made in logistics in organizations is enormous and, although much effort has been devoted to creating structured methods to aid the development of information systems to support these organizations’ logistics, the area of Logistics Information System auditing remains less developed. The major aim of this paper is to provide a systemic approach of the application of expert system technology to Logistics Information Sy stem auditing. Taking a strategic view of M anagement Information System (MIS) in logistics, this paper describes the application of INFAUDITOR, an audit expert system, to logistics information systems auditing. INFAUDITOR has two fundamental features. First, it covers all domains of information systems, managerial (like logistics) as well as technical aspects. Secondly, it helps to determine, in a given audit situation, the respective importance that should be given to the dcrerent audit domains and tests of control. INFAUDITOR can be viewed as consisting of several expert systems as in blackboard systems. Its fact bases include the characteristics of the enterprise, its logistics information system and the audit objectives. Its rule bases encompass the audit criteria represented as a hierarchical tree. INFAUDITOR is used to assess the ability of a Logistics Information System (LIS) to provide decision makers with relevant, timely informationfor designing, planning and maintaining an eflcient production system, for securing materials necessary for production, and for facilitating achievement of low operating and maintenance costs. W e present and discuss results obtained by using INFAUDITOR in auditing the logistics Management Information System of a large European company. Copyright 0 1996 Elsevier Science Ltd 1. INTRODUCTION THE LAST DEC ADE has seen an unprecedented rate of development of computer hardware and software, which has created the opportunity for sophisticated data collection, its conversion to meaningful information and the retrieval of that information. During this period, the concept of the Logistics Information System (LIS) has evolved from earlier uses of computers for data process- ing. It is now defined to include everything which deals with the computer-assisted flow and presentation of information, and can be considered to support logistics data-processing functions including Computer Integrated Manufacturing (CIM). Enormous investment is currently being made in LIS and CIM. However, apart from overall cost-benefit analysis, little attention has been paid to assessing the inherent contribution of LIS to an organization (Laudon & Turner, 1989). There is a growing concern about whether the true capability of LIS is being realized. The work described in this paper centers on the issue of LIS auditing. The auditor’s main objective is to formulate an opinion about the organiza- tion’s LIS. He should obtain relevant and reliable audit evidence sufficient to enable him to draw reasonable conclusions. The auditor’s judgment is influenced by such factors as his knowledge of the organization, its LIS 463
