Currently, Ubiquitous Computing Technology(UCT)-based service scenarios play an important role in estimating the potential of UCT-based service. The purpose of the study is to propose a multidimensional evaluation(ME) methodology for UCT-based service scenarios regarding their possibilities of realization for the future. Our approach contributes to extend service level management in Information Technology Service Management(ITSM) by evaluating the level of a new service in advance. ME consists of three dimensions: technological evaluations, business-oriented evaluations, and user-oriented evaluations. The three types of evaluations are mutually harmonized to check the overall possibility of realization and validity for certain UCT-based service scenarios. Theoretically, ME is developed to overcome the extant evaluation methods for UCT-based service scenarios, which are limited in the number of evaluation criterions. It is also conceived to cope with the limitation of economical evaluation methods (e.g., technological valuation, estimation of financial outcomes such as ROI, ROA, etc. that are difficult to give meaningful results because most of UCT-based services are not fully realized so far. From the practical perspectives, in addition, our approach can be applied to a variety of scenarios due to its domain-independent approach.

Service Providers need to monitor the level of consumer's satisfaction on service they provide continuously and they use appropriate method to measure their operating status. They have to make a plan on their resource and infrastructure to provide their service in the right place at the right time whenever they need. Most previous studies on IT service quality are mainly focused on criteria or levels of quality measurement even though those criteria and levels should be set by considering consumer's needs. And considering for consumer's needs with managerial factors was not found on those studies. So, we suggest deducing quality factors for continuous improvement of IT service management system in this paper as identify the relative priority using QFD method which consider consumers' voices and managerial factors when decide quality factors of IT service management system introduced SLA. We also confirm that our suggestion is practicable and applicable for current operation by case study.

IT governance in order to achieve the strategic goals of the organization, leadership, organizational structure, and the process is defined. In order to achieve IT governance, organizational structure, leadership for spindle formation, maintenance, and standardized processes to specific and an effective ITIL (Information Technology Infrastructure Library) management model is needed. In this study, the K Authority Management Model of IT Governance ITIL - based research on service delivery and customer satisfaction through the effective information for ITSM (Information Technology Service Management, IT Service Management) building measures, information for business planning and performance management PMS (Project Management System, project Management System), survey on ICT service levels established through the process of planning and construction management models such as ITIL future research on the public portion of the proceeds from the ITIL management model can be utilized as a guideline when establishing a theoretical presents a base.

Today, IT governance has also become a subject of attention along with recent technologies such as ITSM (IT Service Management), PPM (Project Portfolio Management) and Compliance. At the national level, the market is fairly recent. and therefore, lacks detailed research in the field. Models specifically related to EIM has not yet been presented to this day, hence, firms that are considering EIM as a potential part of their information management system may fall into a state of disorder in the process of its implementation. To this end, this research attempts to construct an IT governance model for EIM based on existing models, surveys and interviews. In particular, E-discovery has been applied as means of protecting information assets and its use as evidence. In addition, by applying the research model to a particular global firm and then assessing its documentation management system, the overall feasibility of the research model has been tested.

Recently, as both business processes and IT systems become ever more complex. Especially, enterprise applications tend to become unmanageably complex and increasingly costly to maintain. Therefore complexity is the insidious enemy of software development. It is critical to have a methodology that recognizes and manages this enemy effectively. In this paper, we propose ISIS (Integrated System of Independent Subsystems) - the architectural style needed to develop the complex enterprise applications. The ISIS was developed to meet the challenge of reducing the complexity of a larger enterprise application today. It gives us architecture models for reducing development complexity and composite application. The enterprise application is partitioned into a collection of independent subsystems using ISIS decomposition schemes and equivalence relations. We use middleware named ISIS engine that provides a service for subsystems interoperability by enabling the integration of distributed, cross-platform subsystems. We have implemented an ITSM system that achieves our objectives, reducing development complexity, using the ISIS architecture. Finally, ISIS architecture provides greater flexibility and productivity when an organization needs either to change its business processes, or to update the underlying systems.

IT에 대한 의존도와 그에 따른 투자 비용이 증가함에 따라 IT거버넌스에 대한 관심이 높아지고 있는 추세이다. 또한 IT아웃소싱 시장의 확대, 계약 규모의 증가로 인해 IT 아웃소싱의 효과적인 운영에 대한 관심도 또한 높아지게 되면서 IT 서비스 제공을 위한 표준 등 프로세스를 기반으로 한 IT 서비스 관리가 주요 이슈로 떠올랐다. 본 연구는 국내 SI업체 V공급사와 그의 4개의 고객사를 대상으로 고객사와 공급사의 IT거버넌스 및 IT 서비스 관리에 대한 인식에 따른 IT아웃소싱 성공을 평가하였다. 자료의 수집은 IT거버넌스와 IT서비스 관리 프로세스 부문에 대해서는 관련 전문가(key informant)들을 대상으로 인터뷰와 설문을 통해 이루어졌고, IT아웃소싱 성공 평가는 고객사의 사용자(end user)를 대상으로 설문하여 약 200개의 데이터를 확보하였다. 그 결과 IT거버넌스와 IT 서비스 관리 성숙도가 IT아웃소싱 성과에 영향을 끼치는 것으로 나타났으며, IT 아웃소싱 성과를 평가하는 차원들끼리도 전체 만족도에 대해 영향을 미치는 것으로 조사되었다. 본 연구는 IT거버넌스와 IT서비스 관리 프로세스 성숙도가 IT아웃소싱 성과에 미치는 영향을 제시함으로써 IT거버넌스의 중요성을 인식시키고 IT서비스 관리 프로세스 시스템 도입을 고려하는 기업에 지침을 제공하고자 한다.

It's been almost 6 years since PIA was implemented based on legislation. So I analyzed problems of PIA from the perspective of ITSM 3 elements. I mainly took account of quality improvement of the report when I assessed systems processing personal informations. So, I propose in terms of logical validity improvement of assessment report. The improvements on 4 different outputs for each phase are many cases that I assessed systems processing personal informations. And I propose improvements on qualified assessors having capability of GRC and on process for managing the assessment system. To settle down PIA system as the reasonable and effective assessment system even after 2016, the statutory deadline for completion of PIA, assessors and appointed assessment firms and authorities should cooperate to complete the assessment system.

Highly probable cause of the current turmoil critical national infrastructure and private enterprise information systems failures or national event of an accident, it is inevitable huge hit in corporate business as well as a significant impact on the national benefit. This is a trend subject to the stability of the national management information system has a significant impact on people and society, such as banking, telecommunications, transport and energy, which can be extended into a private institution. However, public and private ICT business through the development of Information system Audit or CMMI(Capability Maturity Model Integration) certification check the quality of the target system, but quality check on the reliability of the information system operations after construction is either not promoting met for some safety test results a situation that does not enabled by insufficient. By preventing the disorder or an accident of this study, the diagnostic reliability information systems through inspection and evaluation system development of information systems being established, and to minimize service confusion and study ways to ensure customer - oriented service.
