Nowadays, IS projects are getting more complicated and large-scaled. Therefore, many researchers and practitioners have been interested in the IS development methodologies, automated tools, techniques, and TQM to improve IS performance. Latest Standish Group's research reported that after the PMO introduction, project scale became bulkier than 1 or 2 year ago, and that IS development project success probability was increased sharply by 62 percents from 37. The previous researches listed just various PMO functions. This research is to seize the core functions and management level of the PMO affecting on the IS project performance with banks which are the leading industry to accept the PMO in Korea. The activities in the categories of implementation management technology support management infrastructure management are the core functions of the PMO to affect the IS performance including schedule management quality management user and stakeholders' satisfaction. Also, the PMO management level is important for IS project success. Among the 5 levels PMI suggested, PMO can implement the project effectively at least at the third level. Korean companies which are about to introduce the PMO have to consider the PMO core functions and management level to increase the IS maturity.

PMO의 등장 배경은 치열한 경영 환경 속에서 기엽 생존전략의 일환으로 추진하는 정보화 프로젝트의 성공 가능성을 높이기 위함이다. 프로젝트의 규모는 커지고 도입하려는 정보기술의 난이도와 복잡도, 신규성은 높아가는 상황에서 프로젝트의 성공 확률을 높이기 위한 노력이야 말로 정보시스템 연구 분야에서 항구적인 연구 주제일 것이다. 따라서 정보시스템 구현을 성공적으로 하기위한 많은 연구들이 수행되어 왔으며, 최근에는 PMO의 도입이 실무와 학계에서 일반적으로 수용되는 전략 방안이다. 그러나 많은 선행연구들이 PMO의 역할들을 나열하는 수준에서 크게 벗어나지 못하였는 바, 본 연구는 PMO 도입이 프로젝트 성과에 영향을 준다는 확신을 바탕으로 PMO의 성과에 영향을 미치는 핵심기능들과 관리의 수준을 통합하고 이를 검증하는 프로젝트 통합성과 모델의 제시와, 이에 대한 실증연구를 수행하였다. 즉, PMO의 핵심 기능을 설행관리, 기반관리, 자원 통합관리, 기술지원, 업무와의 연계성 지원 등, 5가지로 정의하고, PMO 핵심 기능들과 PMO 운영수준과의 관계성, PMO 운영 수준과 프로젝트 성과에 대한 관계성 등을 아우르는 통합 모델을 수립하고 각 요인들에 대한 영향관계를 검증하였다. 본 연구는 완전 구조 방정식 모델을 근간으로 이론을 검증하였으며 경로 모델을 통해 변수들 간의 관련성을 검증하였다. 연구 결과, 5가지의 핵심 기능이 모두 프로젝트 관리 성과에는 긍정적인 영향을 미치는 것으로 나타났으며, 기술 지원 업무가 프로젝트의 조직성과에 영향을 마치지 않는 것을 제외하면 나머지 모든 핵심 기능 또한 프로젝트 조직성과에도 긍정적인 영향을 미치는 것으로 나타났다.

Recently the complexity and difficulty of the IT projects are increasing due to technological and environmental risks, resulting in the adoption of PMO(Project Management Office) onto IT project management practices, including public area projects. For example, the Korean government regulated the application of PMO onto large scale public IT projects. However, since there has been no reliable method to estimate the cost to execute PMOs, a PMO cost evaluation model to support the budget and cost planning of PMO projects is required. Thus, the purpose of this research is to develop a systematic cost evaluation model for PMO projects. We identified the dimensions that determine the PMO execution cost to be the scale of the subject project, the technical difficulty level of the subject project, and the tasks to be executed in the PMO project. Based on the determinants, the PMO execution cost model were developed from historical data and experts opinion. Upon verification, the validity of the developed model has high level of consistency compared with their experiences of real PMO project costs.

This study identifies influential factors for invigorating the public management office (PMO) system for system integration (SI) projects in public sectors and analyzes the priority of each factor from the point of different stakeholders, i.e., owners, SI company, and PMO. Based on the literature review, four first-level influential factors are identified: legal system maintenance, owner's capability, SI company's capability, and PMO's capability. Among them, the PMO's capability is determined as the most critical factor by all the stakeholders. Among the second-level influential factors, the capabilities of professional engineers and project managers are considered as important among the PMO's capability, whereas the reasonable consulting fee is considered as the most critical factor among the legal system maintenance. With respect to each stakeholder, project management capability is considered as the most important factor for owners, while the reasonable consulting fee is considered as the most important factor for PMO.

Recent efforts to develop a common standard for nuclear power plants (NPPs) with the aim of creating (1) a digital environment for a better understanding of NPPs life-cycle management aspect and (2) engineering data interoperability by using existing standards among different unspecified project participants (e.g., owners/operators, engineers, contractors, equipment suppliers) during plants' life cycle process (EPC, O&M, and decommissioning). In order to meet this goal, there is a need for formulating a standardized high-level physical breakdown structure (PBS) for NPPs project management office (PMO). However, high-level PBS must be comprehensive enough and able to represent the different types of plants and the new trends of technologies in the industry. This has triggered the need for addressing the issues of the recent operational NPPs and future technologies' ramification for evaluating the changes in the NPPs physical components in terms of structure, system, and component (SSC) configuration. In this context, this ongoing study examines the recent conventional NPPs and technological trends in the development of future NPPs facilities. New reactor models regarding the overlap of variant issues of nuclear technology were explored. Finally, issues on PBS for project management are explored by the examination of the configuration of NPPs primary system. The primary systems' configuration of different reactor models is assessed in order to clarify the need for analyzing the new trends in nuclear technology and to formulate a common high-level PBS. Findings and implications are discussed for further studies.

International construction contracts to Korean construction companies have been dramatically increased over the 48 years (Contract received worth 65.2 billion dollars in 2013). Especially, the plant construction sector has achieved about 61% among the 65.2 billion dollars. Under this trend, in order to ensure plant construction's competitiveness, 'standard classification' is an important area for systematic management. However, these standards in the plant construction are not widely utilized yet, in comparison with civil and building sectors. Therefore, in this research, a higher level of standard classifications is proposed for various types of power plants from a PMO's (Project Management Office) perspective. This study also provides a comparative analysis outlining different features and common components based on various types of power plants.

This paper aims to provide some unique insights into the verification of organisational innovation diffusion through empirically identifying the major factors determining the level of organisational innovation diffusion. The paper presents a two-stage sequential mixed method analysis: structural equation modelling analysis and regression analysis. A questionnaire survey was administrated to a sample of 223 organisations operating in Saudi Arabia. The results suggest that participative culture and, technology availability and implementation would intensify organisational climate for innovation. The results revealed compelling evidence in support of the moderating role of technology on the relationship between country socio-culture and organisational climate for innovation. Equally important, organisational innovation characteristics could play a crucial role in the intention to adopt a particular innovation. Specifically, maintaining Saudi Arabian top management's status quo is an obstacle to organisational innovation diffusion. This paper expands and improves upon the current understanding of how organisational innovation diffusion, in particular the Project Management Office (PMO), can be accelerated. By focusing on the critical factors within the conceptual model, the paper depicts the crucial role of certain factors that could leverage improved organisational innovation diffusion outcomes.

Purpose: In this study, a reliability prediction based reliability growth management is suggested especially for the early development phase of a system and the case study of surveillance system is given. Methods: The proposed reliability prediction based reliability growth management procedures consists of 7 Steps. In Step 1, the stages for reliability growth management are classified according to the major design changes. From Step 2 to Step 5, system reliability is predicted based on reliability structures and the predicted reliabilities of subsystems (Level 2) and modules (Level 3). At each stage, by comparing the predicted system reliability with that of the previous stage, the reliability growth of the system is checked in Step 6. In Step 7, when the predicted value of sustem reliability does not satisfy the reliability goal, some design alternatives are considered and suggested to improve the system reliability. Results: The proposed reliability prediction based reliability growth management can be an efficient alternative for managing reliability growth of a system in its early development phase. The case study shows that it is applicable to weapon system such as a surveillance system. Conclusion: In this study, the procedures for a reliability prediction based reliability growth management are proposed to satisfy the reliability goal of the system efficiently. And it is expected that the use of the proposed procedures would reduce, in the test and evaluation phase, the number of corrective actions and its cost as well.

21세기 기업경영에서 기업 내 IT(Information Technology: 정보기술)의 중요성과 복잡성이 급속히 증가되었고, 기업에서 필요로 하는 IT의 역할이 성공적으로 수행되기 위해서는 높은 수준의 IT 거버넌스와 효과적인 관리가 선행되어야 함에도 불구하고, IT 거버넌스의 확립 정도는 기업에 따라 큰 차이가 있다. 또한 IT 거버넌스 활동과 관리에 대한 실증적 연구 역시 충분하지 않다. 이에 본 연구는 거버넌스 이론을 근거로 하여 IT 거버넌스 활동과 성과, 그리고 기업성과간의 관계를 파악하는 연구모형과 가설을 도출하고 실증적으로 검증하였다. 본 연구는 비즈니스 전략과 IT 전략간의 연계성, IT 계획, 전사적 아키텍쳐, 프로젝트 관리 조직, 서비스 수준 관리, IT 컴플라이언스, 장애관리, 정보시스템 효과성, 가시성, 기업성과 등, 구성개념 간의 가설을 검증하기 위해 LISREL을 활용한 구조 방정식 모형을 개발하였고, 108개의 기업과 기관에 대한 설문 조사를 수행하였다. 연구 결과, 비즈니스 전략과 IT 전략간의 연계성은 IT 거버넌스 활동 중, IT 위원회와 IT 계획에 긍정적인 영향을 미치는 것으로 나타났다. IT 거버넌스 활동 중, IT 거버넌스 위원회, IT 계획, 서비스 수준 관리, 장애 관리는 IT 거버넌스 성과로서의 정보시스템 효과성에 긍정적인 영향을 미치는 것으로 나타난 데 반하여, IT 컴플라이언스는 정보시스템 효과성에 부정적인 영향을 미치는 것으로 나타났다. 또한 IT 계획, 전사적 아키텍쳐, 서비스 수준관리, IT 컴플라이언스는 IT 거버넌스 성과인 정보시스템 가시성에 긍정적인 영향을 마치지 않는 것으로 나타났다. 마지막으로 정보시스템 효과성과 가시성은 기업 성과에 긍정적인 영향을 미치는 것으로 나타났다. 본 연구는 IT 거버넌스에 대한 근거 이론들을 논리적으로 정리하여 IT 거버넌스의 이론적 배경을 체계적으로 확립하고 IT 거버넌스 활동 및 IT 거버넌스 성과, 비즈니스 성과를 포함하는 이차원적 성과를 제시함으로써 학계와 실무 측면에 공헌하고자 하였다.
