Efficient scheduling for software development is a major concern for software engineers. Industries simultaneously try to perform a variety of projects with the limited resources on schedule. A way to overcome the limitation of resources is sharing of the resources through the projects. This study discusses the matrix organization for software development. A scheduling for matrix organization is a special case of project management problem. The ultimate goal of scheduling problem in this study is to minimize the overall duration of the multiple projects. A genetic algorithm is presented to solve the scheduling problem of the matrix organization and is substantiated with numerical results.

Although information communication technology (ICT) is long regard as very useful tool in today's construction engineering and project management environment, organizations must not only operate based upon its original setting, but also requires on-going observation, additional features and fine-tuning actions before the desirable outcome can be achieved. However, it is a very common phenomenon that organizations purchase the licensed "off-the-shelf-software" package and customize it to suit their own business need. Due to the incapability of such software and inefficient customization, the possible result is making that ICT tool not user-friendly and sometimes the whole system becomes obsolete. The purpose of this paper is to review and report those actions taken (between February 2006 and December 2010) by a construction organization to enhance the performance of its Enterprise Resource Planning (ERP) system launched in December 2002. Such actions include: improving data inputting method; removing the transition bottleneck; introducing crystallization function; revising the organization's "Delegation and Limits of Authority"; publishing the "League Table" amongst users; integrating the 3D Mode into the system and upgrading hardware. Whilst the ultimate goals of such system are well beyond the time limit of this research study, an obvious interim result, achieved by this case studied organization, was winning a landmark project worth US$500 million after the ERP system was functioned properly and effectively. Their experience and success becomes an exemplar which can be borrowed by those companies, from managerial perspectives and as a roadmap, planning to adopt information technology (IT) strategy and use ICT tool in the construction engineering and project management framework.

2000년대 이후 많은 한국의 건설 및 엔지니어링 기업들은 급속하게 변화하는 동적환경에서 경쟁 심화, 높은 리스크, 경기 침체, 실적 부진, 이윤 감소 등의 어려움에 직면해 있다. 이러한 도전을 극복하기 위해서는 패러다임 변화에 적극적으로 대응할 수 있는 특별한 역량의 확보가 요구된다. 그 중 하나가 프로젝트 포트폴리오 기반에서 기업 내 조직자원을 적극적이고 통합적으로 관리할 수 있는 프로젝트관리 역량이라고 할 수 있다. 본 연구의 목적은 기업 내 프로젝트 조직자원의 동적역량이 기업의 경쟁우위와 성과에 어떤 영향을 미치는 지를 조사하는 데 있다. 국내 건설 및 엔지니어링 기업의 프로젝트 조직에서 근무하는 직원을 대상으로 설문 자료를 분석하고 구조방정식 모형과 경로분석 등의 통계분석을 통해서 이를 실증하였다. VRIN 조직자원과 조직 동적역량간의 영향을 분석한 결과, VRIN 특성의 프로젝트 조직자원을 보유하고 있다면 프로젝트 조직의 동적역량에 유의한 영향을 미치는 것으로 나타났고, 프로젝트 조직의 동적역량도 기업의 경영성과를 개선하고 경쟁우위를 창출하는데 긍정적인 영향을 미치는 것으로 나타났다. 또한 조직자원은 기업의 경쟁우위와 성과에 직접적인 영향을 끼치며 조직 동적역량이 VRIN 속성의 조직자원과 경쟁우위 사이에서 매개효과의 영향이 있는 것으로 확인되었다. 본 연구가 학문적으로는 자원기반관점과 동적역량관점을 통합하는 입장에서 프로젝트 조직자원이 기업의 경쟁우위에 미치는 영향을 실증하고 프로젝트관리의 학문적 영역을 확장하는데 기여하였다. 실무적으로는, 건설 및 엔지니어링 산업에서 경쟁우위를 확보하기 위하여 기업들이 전략적으로 어떻게 프로젝트 조직자원을 활용해야 하는지에 대한 구체적인 방안을 제시하였다.

Company A, an embedded system manufacturer, has been managing multiple development projects. Executives need to understand the risk level of every project and prioritize resource distribution. Traditional project monitoring tools or excel sheets are too complex for calculating the risk factors across a functional organization. Two new charts, "Spear-head Chart" and "Float Chart" were designed to assist high level decision making processes. Two charts were used for weekly executive meetings in order to monitor project progress and rectify project direction. One page graphical monitoring tools in Company A are good enough for high management decision making. Authors explain the characteristics of two charts and propose its practical implementation in real working environment. Spear-head chart was also implemented as a system.

This paper discusses a scheduling problem on object-oriented developments over multiple teams with limited resources in matrix organization. The objective of the problem is to minimize the makespan of overall projects. There are tangible and intangible advantages such as efficient resource share, improvement of productivity, development efforts and cost reduction, etc. by dispatching resources properly to the development teams. Traditionally, the project scheduling has been done with a manager's intuition or heuristic. We present a scheduling model with illustrative examples, stochastic search approach, and apply a variety of problems generated randomly to the approach. The results are analysed.

With rapid development of information and communication technologies, open collaboration can be eased through the Internet. Open source software, as a representative area of open collaboration, is developed and adopted to various fields. In this research, based on organizational learning theory, we examine the impacts of exploration and exploitation on innovation performance in open source software development projects. We define knowledge exploration as a number of developers from outside organization and knowledge exploitation as the ratio of member of an organization who participated in an open source software project managed by the organization. For analysis, we collect data of 4794 projects from github which is a representative open source software development platform using Web crawler developed by Python. As a result, we find that excessive exploration has curvilinear (invers U-shape) relationship on project performance. On the other hand, exploitation with enough external developers will positively impact on project performance.

The success and failure of any project depends upon many factors, the Project Manager is considered to be the key contributor to the success of any project, as well as a guide to the team members to achieve the client satisfaction (Cost, Time and Quality). Therefore the main aim of this paper is to provide a practical approach for understanding the importance of the Project Manager and his effectiveness to the success of the construction projects. In addition, the Project Manager's roles, responsibilities and duties have direct impact to the success of the construction projects. In order to identify the thoughts and opinion of the construction industry on this particular assertion, a quantitative study was carried out within the UK construction industry. The result of the study shows that there is an extremely strong correlation between the Project Manager and the success of the construction projects. In construction projects the Project Manager is considered to be one of the most important people who can lead and drive the projects in the right direction and conclude construction projects successfully. Moreover, these can play the most important role regarding the improvement of the organization's performance, the organization's profitability and the client's satisfaction. The research confirmed that the Project Manager is a very essential element to the success of the construction project and have an impact at every stage of the construction project. So it concluded that selection of a Project Manager should be carefully done with regard to experience, knowledge, power/authority and good understanding to the kind of the project.

Project management is a tool for smooth operation during a full cycle from the design to normal operation including the schedule, document, and budget management, and document management is an important work for big projects such as the JRTR (Jordan Research and Training Reactor). To manage the various large documents for a research reactor, a project management system was resolved, a project procedure manual was prepared, and a document control system was established. The ANSIM (Advanced Nuclear Safety Information Management) system consists of a document management folder, document container folder, project management folder, organization management folder, and EPC (Engineering, Procurement and Construction) document folder. First, the system composition is a computerized version of the Inter-office Correspondence (IOC), the Document Distribution for Agreement (DDA), Design Documents, and Project Manager Memorandum (PM Memo) works prepared for the research reactor design. Second, it reviews, distributes, and approves design documents in the system and approves those documents to register and supply them to the research reactor user. Third, it integrates the information of the document system-using organization and its members, as well as users' rights regarding the ANSIM document system. Throughout these functions, the ANSIM system has been contributing to the vitalization of united research. Not only did the ANSIM system realize a design document input, data load, and search system and manage KAERI's long-period experience and knowledge information properties using a management strategy, but in doing so, it also contributed to research activation and will actively help in the construction of other nuclear facilities and exports abroad.

Project management is critical for the success of the large and complicated IT project. Accordingly, to improve the efficiency of the project management, operation of separate Project Management Office (PMO) organization is getting important. Despite the appreciation of PMO as necessary for project success, the result has not always been positive. In this respect, we intended to formalize the PMO success model by incorporating necessary factors related to PMO services and capabilities, and their relationship. Empirical testing results verified critical antecedents comprising PMO services, which included schedule, quality, budget and others. Furthermore, moderating impacts of PMO capabilities are quantitatively assessed. The research findings offer practical insights for successful management of PMO.
