The importance of IT service management to improve the effectiveness and efficiency of IT outsourcing practices or performance has been emphasized in the fields. Accordingly, several methodologies of IT service management have been adopted in a fashion. This case based research tries to analyze the effects of ITIL-based IT service management practice in a company on IT outsourcing performance. The case analysis shows that ITIL-based service management influences systems quality, information quality, and service quality in direct manner. But it does not influence systems use and systems satisfaction in a meaningful way. This study would help IT service managers construct IT service environment which improves the performance of IT outsourcing service delivery and also researchers set up research proposition in a concise way in the future.

기업의 IT 환경이 시스템 중심에서 비즈니스 중심으로 바뀌어감에 따라, IT Process 관리를 위해 ITIL 모델 기반의 Service Support 시스템들이 개발되고 있다. 대다수의 이들 시스템들은 application 관리 기능을 다루고 있지 않으나, application 의 변경으로 인한 장애 발생을 최소화하고, 장애발생 시 비즈니스에 어떠한 영향을 미치게 될지 짧은 시간 내에 진단하고 복구하는 것은 장애관리 측면에서 중요한 기능이라고 할 수 있다. 이러한 기능은 application 이 시스템에 의해서 관리되고 비즈니스와 application, infrastructure 의 연관관계가 Knowledge DB 를 통해 축적됨으로써 더 효율적으로 운영될 수 있다. 따라서, 본 논문은 기존의 Service Support 시스템에 application 관리 프로세스를 보완하여 기능을 개선하고자 하였다.

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.

전세계적으로 스마트폰, 스마트패드 등의 모바일기기의 사용은 빠르게 확산되고 있으며, 모바일 환경에서 제공되고 있는 웹 서비스 시장도 급변하고 있다. 특히, 모바일 환경에서는"Any time, Any where" 특성에 따라 사용자의 빠른 피드백이 가능하게 되었으며 이에 따라 서비스 운영 업체는 사용자의 빠른 피드백에 대한 신속한 대응이 요구되고 있다. 이러한 웹 서비스 시장의 변화는 기존의 서비스 개발과 운영 프로세스간의 단절적인 관점을 통합적인 관점으로 변화시키고 있다. 이에 본 논문에서는 모바일 기기 환경에서 제공하고 있는 웹 서비스에 대한 다양한 관점에서 잦은 개선 요청에 대한 피드백에 신속하고 정확하게 대응하기 위한 통합적인 프로세스를 제안한다. 제안된 프로세스는 ITIL 운영 모델 내에 개발/테스트 프로세스를 통합하고 있으며, CMMI-SVC 모델에 적용하여 이전보다 더 많은 프로세스영역에서 충족하고 있음을 보여주고 있다.

IT(Information Technology) has focused on infrastructure-technologies in the past but now focuses on IT service. Many companies strive to save costs and improve IT services. For this reason, they strive to implement a good internalization of ITSM (IT Service Management) by developing ITSM systems based on ITIL (Information Technology Infrastructure Library) from the late 2000s. In particular, IT service operations are one of the structure elements of ITIL version 3 and are highly related to the internalization of ITSM. However, in spite-of-the successful implementation of ITSM, the efficiency of IT service management has not improved due to iterative issues. Therefore, this study developed a user-centered training system by defining the iterative issue guidelines and implementing a database. The implemented user-centered training system provided IT service users with regular training services to produce a good solution for iterative issues after connecting the operation part of the ITSM system. Based on the results of this study, we expect that the proposed ITSM system will contribute to efficiently managing IT services by improving the limitations of IT service operation in the ITSM system.

This study is to guide to estimate service quality on ITSM operation based on ITIL(IT Infrastructure Library). ITIL v2 and v3 provide how to integrate framework of IT service and business process. It is widely used as ITSM operation base. As a latest IT trend, ITSM covers Hardware, Software, SaaS, Network, Call center, Helpdesk, ASP portal and IT operation. Servicedesk is selected as target area where valid sampling is addressable and service change is rapid. Traditional Helpdesk was focusing on technical support to solve internal IT issues passively. But it was evolved into Service Desk which focus in process and provide integrated service from customer's business view point preventively and proactively. Accordingly outsourcing types business are normally performed by group of professional capability. Service quality is measured under the SLA(Service Level Agreement). This study utilized SERVQUAL model as service quality measuring tool developed by Parasuraman, Zeitaml and Berry to find critical factors to satisfy customer. And test was processed regarding effectiveness of IT organization and customer view point thru sampling. Though valid parameters can be changed by ITSM areas under the SERVQUAL models, they naturally can be accepted as a index of service quality measurement after sampling test with acceptable significance. And I recommend to follow this study as a preparation before official SLA.

Researches, studies, and most administration services at the universities are currently carried out through computers. So the IT infrastructure and. the information system of the university are becoming complicated. When a user has problems in using the information system, it is very difficult to get solution for that problem even a computer center or a help desk exists. In this paper we propose a method to establish a service desk based on the ITIL(Information Technology Infrastructure Library) to support efficient learning at the universities. The proposed method in this paper can be used to establish a systematic learning support system when errors of computation happen in learning, researches, and administrative tasks at the universities.

These days, business environments are rapidly change and companies are taking the pressure about a customer value enhance to the continuance from the market. Therefore companies propel various innovative and strategic initiatives for a customer value enhancement. Also Information Technology is rapidly becoming part of our everyday lives due to its fast development, the functions and responsibilities of CSC(Consolidated Service Center) are undergoing revolutionary change. The function of sales organization based on the manpower and human networks are gradually shrinking, and CSC is slowly establishing itself as the company's core parts as its function expands and its operations are in the spotlights. Among these, many organizations are currently introducing ITSM concept for primary processes as a means of achieving synergy in operational excellence, reducing costs and improving service quality. In this thesis, we propose an extended CSC, which is applied ITIL Process to traditional BMP. It also needs to manage more effectively business process model, to modeling rapidly changing business process, and to developing its business application programs whenever and whatever it is changed. The ITSM(IT Service Management), which is an ITIL tool, effectively managing for dynamically changing the business process.

This paper proposes various measures of reliability, maintainability and availability in information technology service management(ISTM). Global ITSM standards such as ITIL(IT Infrastructure Library) and ISO/IEC 20000 are introduced. Especially availability management of De-facto and De-juire standards is concerned with users and customers of IT service. The study presents seven reliability measures, six maintainability measures and two availability measures. These results can be effectively used with a appropriate IT availability management tools such as CFIA(Component Failure Impact Analysis) and SOA(Service Outage Analysis), etc.
