그 동안 IT 아웃소싱에 관한 많은 연구성과에도 불구하고 아웃소싱 계약체결에 있어서 실무적으로 꼭 필요한 아웃소싱의 적정가격에 관한 연구는 매우 미진한 형편이다. 특히 아웃소싱 의뢰업체 입장에서의 적정가격결정 모형이나 사례를 찾아보기는 더욱 어려운 것이 현실이다. 아웃소싱 가격의 적정성은 공급업체 만이 아니 라 의뢰업체의 입장에서도 아웃소싱의 성패를 좌우하는 중요한 요건이다. 본 연구는 TCO 개념을 이용하여, IT 아웃소싱 의뢰업체의 입장에서, 적정 가격을 산정하는 모형을 실제 적용사례를 통해 제시한다. 본 연구는 아웃소싱을 하지 않을 경우의 총소요비용과 아웃소싱을 할 경우의 총소요비용을 비교하여 아웃소싱의 효과를 측정하고 계약가격의 적정성을 판단할 수 있도록 하고자 하였다. 본 연구를 통하여 제시한 TCO분석방법 및 결과는 아웃소싱을 준비하거나 계획중인 업체에게 자체적으로 아웃소싱 계약가격을 산출하고, 아웃소싱을 통한 비용절감항목을 판단하며, 계약가격을 비교할 수 있는 자료로 사용되어 지기를 기대한다.

It is well known that SaaS(Software as a Service) changeover gives several advantages to organization. One of the advantages is the cost reduction effect of IT resources as well as IT human resources. Another one is the curtailment of software development workload in the field of informatization promotions. Nonetheless, it is hard to find comparison cases regarding the quantitative measurement of the introduction of SaaS before and after. Accordingly, when the Government IDC tries to adopt SaaS, it absolutely needs the empirical study whether SaaS is cost-effectiveness or not. In this study, we focus on variation in the Government administration common tasks, processes and labor costs. Using the Man-Month(MM) estimation methods, We verify that how much TCO(Total Cost of Ownership) is reduced per year.

최근 정보보호의 중요성에 대한 인식이 확산되고 있음에도 불구하고 정보보호에 관한 적절한 투자가 이루어지지 않아, 효과적인 정보보호 시스템 구현이 지연되고 있다. 이는 전 세계적인 경제불황이라는 원인도 있겠지만, 정보보호 투자에 대한 정당화 논리가 부족하여 최고 경영자의 의사결정에 적절히 반영되지 않은 이유가 더 크다고 할 수 있다. 정보보호는 조직의 업무 수행에 수반되는 부대비용 개념으로 인식되어 왔으며 이 결과 ROI 와 같은 정보보호 투자에 대 한 정당화 논리를 제공하지 못해 적절한 투자가 적절히 수행되지 못하였다. 따라서 최근에는 정보보호 투자에 대한 수익과 지출간의 관계를 통한 ROSI(Return on Security Investment) 분석을 통한 정당화 논리 전개에 대한 필요성이 대두되고 있다. 본 논문에서는 ROSI 산출에 대한 접근방법을 비교 분석하고 TCO(Total Cost of Ownership)를 이용한 ROSI 방법을 제시하고자 한다. TCO는 하드웨어 가격뿐만 아니라 기술지원 및 유지 지원 인력 등을 모두 고려한 총 소유비용이다. 즉 정보보호에 대한 정확한 총 비용을 구하는데 매우 적합하다고 할 수 있다. 본 연구의 결과는 기업들로 하여금 좀 더 효과적인 정보보호 투자 정당화 수단으로서 활용될 수 있을 것이다.

This case study quantifies the savings that can be realized through integration in National Computing & Information Agency (NCIA) of the Korea Government. It is based on the process of the NCIA development project that consolidating and integrating distributed 24 agencies. And it used the widely accepted Gartner TCO (Total Cost of Ownership) Solution and applies that methodology consistently before and after integration. Specific measurement items for examining the information system integration saving cost are developed pilot test for 2 agencies through compare TCO before integration and TCO after integration. The results of measuring on information system integration in NCIA are showed lots of economic cost reduction in TCO by integrating and consolidating each computing environment in agency. Especially in detail, NCIA realized the most savings in IT Capital Cost including development of hardware, software and recovery system. Also IT Support Cost and IT Administration Cost examined more savings than before IT integration.

This study proposes the methodology of analyzing the expected performance of the Integrated Computing Environment(ICE) on the assumption that the ICE of the agencies and the affiliated organizations under Ministry of Culture and Tourism is constructed and operated. The main objectives of the study are as follows : 1) deriving the performance criteria divided into the operational expected value and the strategic expected value of constructing and operating the ICE for Culture and Tourism informatization, 2) proposing the ways of extracting the detailed criteria for four performance areas(the degree of jnformatization efficiency, the degree of public service, the innovation and development of IS organization, the culture and tourism value creation) to evaluate the operational expected value based on the BSC(Balanced Scorecard) Perspective by using the CSF(Critical Success Factors) methodology, and 3) developing the detailed performance criteria and measures for the economic evaluation of the informatization efficiency from the TCO(Total Cost of Ownership) perspective and suggesting the practical evaluation method by applying them to the case of Culture and Tourism informatization.

Government agencies have many difficulties for the information system development and operation. One of the difficulties is a budget estimation. Each government agency suggests individually different estimation for the personnel expenses and IT infrastructure adoption costs in the same field of informatization promotions. The other one is the operation costs are increased exponentially in every year[42, 51]. Those difficulties make government agencies can not help adopting SaaS. In fact, most of IT consulting company and government agencies already recognized a variety of SaaS advantages. The most typical SaaS's advantages are cost reduction, Software rapid development and deployment. However, once government agencies decide to adopt SaaS, they can not avoid many problems and difficulties. There is no information in a detailed item in a budget. In those kinds of situation, there is no choice whether government agencies accept SaaS provider's suggesting adoption costs or not. Thus, we provide a sheet of SaaS adoption cost estimation to government agencies. To know the cost factors, this study uses TCO(Total Cost of Ownership)'s criteria. To give a management point, this study uses Gartner's Application development Life Cycle. In this study, the integration check framework which is SaaS adoption cost estimation makes government agencies possible to establish a adequate budget.

본 논문은 CC-NUMA 시스템과 같은 다중 컴퓨터 시스템에서 분산된 자원에 대한 효율적인 관리 및 진단을 위한 프레임웍의 설계에 대해 기술한다. CC-NUMA 시스템이란 고성능 상호 연결 망에 결합되어 하드웨어 방식으로 메모리 일관성을 제공하는 다중 컴퓨터이다. 이러한 시스템은 주로 엔터프라이즈 서버용으로 사용되기 때문에 TCO(Total Cost of Ownership)에 근거한 관리 및 지난 기능이 필수적으로 요구된다. 본 연구는 고성능 멀티미디어 서버(MX-Server)의 진단 및 관리 기능으로 제공되는 SDC(Server Diagnositc Card)의 하드웨어 및 소프트웨어 구조 설계 시 고려사항에 대하여 논하였다.

과거 고객들은 연속식 잉크젯 프린터를 도입할 때에 구입비용에 중점을 뒀다. 그러나 최근에는 소모품을 포함한 유지비용까지 고려하는 것으로 소비패턴이 변화하고 있다. 총소유비용(Total cost of ownership, 이하 TCO)까지 따진 후에 구입하기 때문에 본체 가격이 저렴한 것은 큰 매력이 되지 못하고 있다. 이처럼 까다로운 소비자에게 다가가기 위해 잉크젯 프린터는 어떠한 기능을 갖춰야하는지, 비디오젯 테크노롤지의 Anthony Blencowe 연속식 잉크젯 프린터 글로벌 사업부 이사와 함께 잉크젯 프린터를 둘러싼 최신 트렌드에 관해 이야기해보았다.

Despite of growing concern for developing meteorological satellites, poor investment has been realized to acquire effective and efficient satellite image processing technologies. In this study, not only qualitative exploration on mapping each elementary technology into related industries but quantitative inter-industry analysis induced from Total Cost of Ownership (TCO) of the Korean satellite image processing system were performed. Furthermore, economic assessment has been made by estimating internal rate of return(IRR) for the benefits returned versus TCO of the system. The results showed that agriculture and fisheries industry, tourist and leisure industry, and transportation industry were highly related with the acquisition of the system, and that 9.1 billion won of production-induced effects, 3.3 billion won of value-added-induced effects, and 54 individuals of employment-induced effects were anticipated except for those of directly relevant industries. Even in the pessimistic scenario, 7% of IRR exceeding 5.5% assumed as current public rate was postulated, consequently, the investment was fairly justified.

The purpose of this paper is to develop a new method for information system sizing and selection based on a hybrid mixture of simulation and genetic algorithm, and to show its cost-effectiveness by applying it to a real world problem. To serve this purpose, we propose an operational model which identifies a set of system alternatives using simulation, and determines the optimal one using genetic algorithm. Specifically, with simulation, we generate probability distributions describing real data gathered from actual system, which can overcome the major weakness of the existing methodology that normally employs point estimates of the actual data and constant correction factors without theoretical rationale. We next search for the optimal combination of H/W, the number of CPUs, and S/W, which meets both of our business goals of incurring low TCO(total cost of ownership) and maintaining a good level of transaction processing performance. Experimental result shows the proposed method in this paper saves the cost while it preserves the system's capacity within allowable performance range.
