IT 아웃소싱 운영의 효율적이고 품질 높은 서비스를 제공하기 위하여 정보시스템 운영 원칙을 세우고, 그 원칙을 통하여 운영관리가 이루어져야 한다. 따라서, 정보시스템 운영관리 프로세스를 참조한 정보시스템 운영관리 프로세스의 정립이 필요하다. 정보시스템 운영감리는 구축 개발 감리와는 다르게 일회성이 아닌 매주기별로 지속적인 감리가 필요함으로 운영관리 프로세스의 변화에 따라 운영감리 지침도 보완이 이루어져야 한다. 이에 본 논문에서는 IT아웃소싱 운영을 위한 정보시스템 운영감리 모형을 제안하였다. IT서비스 영역을 참조하여 계획, 전략, 계약, 서비스, 관리 등 IT아웃소싱 운영관리를 위한 정보시스템 운영감리 모형 및 점검항목을 제안하였으며, 도출된 감리모형 및 점검항목은 전문가들의 설문조사를 통하여 제안한 모형의 적합성을 검증하였다.

현재의 운영감리는 정량적 접근방법이 아니라 감리인의 주관적 판단에 의존하고 점검항목을 어떻게 적용할지는 감리인 재량에 따라 편차가 크다. 이러한 관점은 감리인의 전문성에 따라 보다 상황에 맞게 적정한 점검이 이루어지는 기회가 되기도 한다. 하지만 시스템 구축 보다 시스템 운영에 있어서는 맞지 않는 것이 현실이다. 운영시스템은 구축후 지속적인 운영이 필요한 시스템으로 운영감리 때마다 다른 점검항목을 적용한다면 감리결과에 대한 신뢰성을 확보할 수 없고, 감리결과의 활용도 제한적이 될 수밖에 없다. 이에 본 논문에서는 정보시스템 운영 상태를 정량화된 운영점검표로 측정하도록 함으로써 운영감리를 개선시키고, 그 효용성을 높이고자 한다.

The purpose of constructing university information system is for improvement in diversification and throughput of information, streamlines business processes, rapid exchange of information, sharing of information, decision-making information, and securing educational facilities. Similar to business information technology system, university information system does not have a review system for sharing and overlapping investment of information. Due to the lack of project management for outsourcing and vulnerability of system suitability, system audit is absolutely needed for the university information system. This paper especially focuses on an operational phase in the audit of university information system. Additionally, we proposed operating model and checklists of the university information system based on Management Guidelines of ITIL V3 Operational and Information System. We derived the checklists of operation audit by each domain of service strategy, service design, service transition, service operation, and continual service improvement. As the result, this study appear to have more than average satisfaction the suitability results were.

According to Railway Safety Act, Korea Transportation Safety Authority (KOTSA) has been entrusted with 'Integrated Railway Safety Audit (IRSA) and has implemented the safety audit to the Railway operation agencies such as Korea Railway (KORAIL) and the Railway facility management organization such as the Korea Rail Network Authority (KR Network). The target of IRSA is to establish the effective rail safety management system and to raise the safety level of the Railway operation and facility agencies by checking synthetically their performance of safety duties with sincerity according to the Railway Safety Act. Even though newly introduced IRSA is conducted smoothly, it is necessary to study the methodology and criteria of the state's safety audit system. The purpose of this paper is to improve the efficiency of IRSA by the comparative research between IRSA and other similar safety audit system and to establish the consecutive improvement concept of IRSA. Second purpose is to confirm the effectiveness of IRSA by the analysis of the relationship between audit results and the safety level of the rail operation agencies.

본 연구는 데이터를 기반으로 개인 또는 기업들이 무한한 이익을 창출하는 사회가 되면서 데이터 품질을 중심으로 데이터베이스 운영관리의 중요성이 증가하고 있는데 이를 체계적으로 관리하는 국내 공공, 민간 기업이 많지 않은 상태에 대한 현황 및 문제점을 분석하고 감리인의 입장에서 개선방향을 구명하고자 하였다. 본 연구를 수행하기 위해 개선된 감리 점검항목을 도출하여 이를 기반으로 감리인 및 IT 전문가들을 통해 설문조사를 하였고, 최종 자료를 분석에 활용하여 연구 가설을 실증적으로 검증하였다. 분석 결과, 데이터 품질에 기반을 둔 데이터베이스 운영관리의 개선된 감리 점검항목에 대하여 감리인의 입장에서 모든 점검항목에 대해 매우 만족한다고 나타났다. 또한 비 감리인에 입장에서도 수용범위에 포함된다고 확인되었다. 본 연구를 통해서 정보시스템 운영감리와 기업의 데이터 운영관리의 수행에 이를 활용하여 개선할 수 있을 것이다.

Recently the assurance of railroad safety is very important issue in KOREA because there are lots of changes in the railroad industries. The Railway Safety Act was established in order to cope with these changes effectively and prevent the railroad transportation accidents. According to this law, Korea Transportation Safety Authority (KOTSA) has been entrusted with 'Integrated Railroad Safety Audit (IRSA)' and has implemented the safety audit to the railroad operation agencies such as Korea Railroad (KORAIL) and the railroad facility management organization such as the Korea Rail Network Authority (KR Network). The target of IRSA is to establish the effective rail safety management system and to raise the safety level of the railroad operation and facility agencies by checking synthetically their performance of safety duties with sincerity according to the Railway Safety Act. The purpose of this paper is to improve the efficiency of IRSA by the comparative research between IRSA and other similar safety audit system. To study the efficiency of IRSA, we investigated the rail safety audit systems of EU system specially France, England where the big changes have happened for the rail operation concepts and Japan where government entity control the railroad safety. The international standards of Occupational Health & Safety Assessment Series (OHSAS 18001), Quality Management System (ISO 9001) and Guidelines for Quality and/or Environmental Management Systems Auditing (ISO 19011) are investigated.

With the growth and maturation of IT industry, the necessity of audit about development, maintenance and management of high-quality information system is gradually increasing. In addition, the necessity of inner auditing system, which could totally verify and evaluate the effectiveness of project according to the characteristics of organization conducting information-oriented business, also being proposed. Government offices including Korea Institute of Science and Technology(KISTI) collectively controlling nationwide science-technology related information have no guiding principle or organization within themselves even though performing information-oriented businesses are becoming more bigger and complicated. In this paper, we propose scheme for devising framework, which can audit construction and operation of knowledge information, check list and guideline. In addition, we present concrete ways for adapting these schemes to institutes which manage science-technology knowledge information. Audit framework consists of points of time in audit, audit domain and audit criterion. Points of time in audit are defined as three phases as followings: pre-audit, in-progress audit and post-audit. Audit domain includes 16 detail audit domains and especially we set 11 check items and 40 detail investigation items for database implementation business. We expect that management level of science-technology implementation business of organizations using this research result will increase and they could offer high-quality information service.

데이터 감시(AUDIT) 기능이란 분산 실장 되어 있는 데이터들을 대상으로 데이터 이상을 진단하고 불일치 데이터를 검출하여 이를 일치시키는 일련의 작업을 말하는 것으로 데이터 불일치로 인해 유발되는 시스템 문제를 최소화시키는데 목적을 둔다. 본 논문에서는 ATM 교환기의 연결 데이터의 대부분을 차지하고 있는 PVC(Permanent Virtual Circuit) 데이터에 대한 감사 기능 지원 방안을 제안하였다. 즉 고속/저속 가입자 링크에 대해 일정 시간마다 감사 기능의 주기적 수행과 운용자 명령어에 의한 즉각적인 감사 기능을 제안하여 PVC 정보의 불일치로 인한 데이터의 손실 및 시스템 장애를 최소화 할 수 있게 하였다. 또한 감사 기능으로 인해 연결 제어 프로세서와 DC(Device Controller) 사이에 송수신하는 많은 IPC(Inter Processor Communication) 메시지가 연결 제어 프로세서의 부하에 어떠한 영향을 미치는지 분석하였는데, 시스템 부하와 거의 무관하게 연결 제어 프로세서의 부하가 일정함을 확인하였다.

In the case of an agile-based project, it was inadequate to perform a comprehensive inspection and evaluation on the establishment and operation of an information system by performing audit only with the audit and inspection elements provided by the existing information system audit and inspection system. In particular, in the case of the test activity area, it was necessary to improve the test activity audit check items to comprehensively check the agile-based development process by applying the existing audit system. To this end, a test activity improvement check model of the agile methodology audit model was presented by applying the repetition concept, a characteristic of the agile methodology. In order to empirically verify the model of this study, a survey was conducted for auditors and designers/developers who have experience in performing agile-based projects and auditing information systems. As a result of the questionnaire on the integrated test and system test in the test stage, more than 70% of the respondents were found to be suitable. More than 80% of the respondents judged that it was appropriate as a result of the questionnaire on "improvement and regression test progress according to integrated test and system test results" and "integrated test and functional actions of components and subsystems".
