  • Recently, as Information System projects tend to be more complex, the importance of Information System Audit increases. In the same context, the need for the resident IS Audit also increases, which is supposed to deal with the possible risks and urgent issues by providing the appropriate support and timely coordination during IS project. Basically, for the effective IS Audit, the IS audit team members should be able to understand such a business context as work characteristics, business knowledge, goals, and culture of the organization. The audit team members should also be able to share the various knowledge of Information Technology and audit procedure with the owner of the project. Especially, for the resident audit, it is more important to fill the gaps in expertise between project owner and audit team. However, any studies on the need of common knowledge base (knowledge complementarities) in the IS audit have not been done so far. The purpose of this study is to analyze whether the knowledge complementarity based on inter-organizational communication between the project owner and audit team members makes an effect on the fidelity and performance of IS audit. In order to do this, the relationship among inter-organizational communication and knowledge complementarity, the fidelity of IS audit service, and performance of IS audit has been analyzed, using Structural Equation Model. The result shows that all the relationship is significant, which means that knowledge complementarity between the two different interest groups should be an effective factor on the fidelity and performance of IS audit. This result implies that, for better quality of IS Audit service, how to acquire the knowledge complementarity between the project owner and Audit team should be considered seriously as well as systematically in the process of IS Audit.

  • IS audit has been regarded as contributing to the improvement of the quality of information Systems, recently, it has been argued that it is not possible to expect a effectiveness, because it can offset the schedule burden due to the preparation of additional documents for Audit and it affect to the project schedule. The effectiveness and quality criteria of IS audit are different between groups, because IS audit is responsible for checking the results and process of the developer company. In this study, we modeled between IS effectiveness and auditor competence, audit firm competence, IS audit standards. As a result, it was concluded that auditor competence, audit firm competence, IS audit standards have a positive effect on IS audit effectiveness. However, according to the result of comparing between interest groups, audit firm competence and audit standards were significant in auditor group, but audit standard was significant in requesting organization and developing company thought that auditor was a important factor to audit effectiveness.

  • This study investigates the association between corporate international diversification and audit fees and audit hours. Korean firms' overseas investment has rapidly increased in recent years and the trend of international diversification is expected to accelerate in the future. Thus, it is important to investigate how auditors respond to globally diversified firms. Our empirical findings show that internationally diversified firms incur higher audit fees and audit hours. This suggests that auditors perceive global diversification as being a higher business risk and require higher external audit fees so that they can decrease audit risk arising from inherent organizational complexity. Further, auditors expand audit procedures to collect more audit evidences, exerting increased audit effort. This study provides empirical evidences that corporate global diversification results in higher audit fees and audit hours. Auditors may refer to these results when planning their audit and determining audit fees and audit hours.

  • Prior literature shows that audit market concentration which is measured as the Herfindahl index is negatively associated with audit quality in Korea. This study analyzes whether characteristics of an audit committee have effect on the relation between audit market concentration and audit quality. This is because it is expected that effective audit committees restrict the tendency of dominant auditors to neglect their duties. The empirical results of this study using the sample firms having an audit committee listed in the Korea Composite Stock Price Index market for 2006-2015 are summarized as follows. First, consistent with prior research, audit quality decreases as audit market concentration increases. However, audit quality is not lowered as audit market concentration rises only when the audit committee has financial expertise among representative characteristics of an audit committee - independence, financial expertise, and activity. This research finds contributions in that it explores the effect of audit committee characteristics on audit quality in consideration of audit market concentration and utilizes the differential types of the characteristics of an audit committee at the same time.

  • The recently revised Act on External Audit has taken effect as of November 2018, where standard audit hour rule is included to enhance the audit quality requiring appropriate audit hour input. It has two issues, one is how much the standard audit hours should be and the other is how to control the auditor proficiency between positions when deciding standard audit hours. This paper focuses on the latter issue and studies if auditor proficiency measured with the KICPA position proficiency weight is economically meaningful and has audit quality implication. The KICPA proficiency weights of partner and junior CPA are 1.2, and 0.4 with senior CPA being 1. The results are as follows. First, we find that the audit proficiency decreases discretionary accruals, the proxy of audit quality. Second, the degree to which the audit proficiency decreases discretionary accruals is pronounced with non-big4 firm. The results imply that the KICPA position proficiency weight reflects auditor experiences which help to improve audit quality.

  • The construction of the Geographical Information System(GIS) is continuously in progress, and with the diversification and complication of the system, the importance of its audit is further deepened. At this point in time, the information system audit has been obligatory as it has been stipulated in law, and the GIS audit has come to follow the criterion of the information system audit since it belongs to the information system audit category. However, it was found that there was a difference between the current information system audit standard and the former GIS audit standard, and the audit checking items for the efficient GIS audit is necessary. For this reason, this paper surveyed the characteristics of GIS in accordance with this necessity, analyzed the GIS audit checking items found in the audit performance guideline of the GIS audit standard, and studied the GIS development methodology through the related literature. In addition, this paper also elicited and proposed the audit checking items for the efficient GIS audit based on the findings of this paper. Finally, this paper confirmed the efficiency of the GIS audit checking items proposed here through the comparison of the actual cases of GIS audits.

  • This research is to suggest the factor which is effecting on the information system audit fidelity in the perspective of audit procurer, to develop the measure to evaluate it, to investigate the audit performance and project performance for comparison the audit fidelity between the audit teams. As the analysis results, we found that the audit service factors can be divided to the expert knowledge of auditor and the project attributes itself. It means these factors are the major measures for the audit fidelity. In this research, the hypothesis of this study model is verified throughout the factor and corelation analysis, and the structured equation model is applied. Analysis results show that all relations between the factors are significant statistically. The audit service factors has an effect on audit fidelity. Also the information system audit fidelity can be affect on the project performance, audit performance and customer satisfaction. So, in conclusion, we need to judge closely the audit service factors affecting the audit fidelity for the enhancement of the project performance, audit performance and customer satisfaction.

  • The current information system audit merely inspects a web based information system by focusing on checking items that are extracted from structured and information engineering model and object-oriented component model. As a result, the checking item of web contents and design is inadequate. This paper aims to extract audit framework in order to strengthen the audit of web contents and design during the development of the web based information system and to suggest checking items based on audit framework. For this, the web development process and web site evaluation model were studied, compared, and analyzed with the current information system development audit. From a result of the survey, it was found that the adequacy of the suggested audit framework and audit checking items is above the average value. It is believed that the suggested audit framework is helpful for the audit of web based information system.

  • Purpose: This paper aims to investigate (1) whether the interviewed auditors conduct higher quality audit than the non-interviewed auditors and (2) whether the frequency of audit engagement interviews has an impact on audit quality. Research design, data, and methodology: Using a sample of Chinese A-share listed firms between 2011 and 2019, this paper empirically tests the effect of audit engagement interviews on auditor's behavior. We collect the data of audit engagement interviews on the CICPA's website. We use OLS regression, fixed-effect model and random-effect model to examine the association between audit engagement interviews and audit quality. Results: Findings indicate that the audit quality of the interviewed auditors is significantly greater than that of the non-interviewed auditors. The frequency of the audit engagement interviews is positively associated with audit quality. The interviewed auditors spend significantly more time on the audit. Furthermore, the positive association between audit engagement interviews and audit quality only exists in non-Big 4 auditors. Conclusions: Our findings provide evidence for the effectiveness of audit regulation enforcement. The results suggest that in an emerging market with weak legal systems, preventive regulations such as audit interviews have a deterrent effect and are necessary in alleviating information asymmetry and improving information environment.
