국내 시스템 구축(System Integration) 및 유지보수(System Maintenance) 사업은 긴 사업 기간과 함께 하나의 사업을 다양한 업체와 함께 협력하여 개발을 하며 운영되고 있다. 이 중 대형 IT서비스업체는 컨설팅 및 제안을 통해 고객의 업무와 요구사항을 파악하며, 프로젝트를 이끌기 위해 방법론을 적용하여 사업 체계 관리 및 운영을 주로 담당한다. 그런데 이와 같은 관리 위주의 사업을 진행함으로써 임직원들의 개발 역량 부족 문제가 발견되고, 이것은 시스템에 대한 이해도 부족으로 다양한 업체와 협력하는데 있어 커뮤니케이션 문제로 직결되어 시스템의 품질 및 결함에 영향을 주기 때문에 이에 대한 대책 및 예방활동이 필요하다. 또한, 작은 국내 시장에서는 이미 경쟁이 심화 되어 포화 되었으며, 대부분의 IT서비스기업은 SI사업에서 솔루션사업으로 변모하기 위해 노력 중이고 국내 시장에서 해외 시장으로 눈을 돌리고 있으므로 직원들에 대한 기술 역량이 시급한 실정이다. 이와 같은 상황에 기업은 준비가 미흡할 뿐만 아니라 해당 활동을 수행하기 위한 필요한 지식 및 방법을 익히는데 어려움이 있는 상황이다. 본 논문에서는 이러한 상황을 극복하기 위해 대형 IT서비스업체에서 진행된 개발역량강화 학습조직 적용 사례에 대해 소개를 하고, 이에 대한 효과 검증을 해보고자 한다.

The key to developing software with the lowest cost and highest quality is to implement or fit the software development process into a given environment. Generally, applying commercial or standard software development processes on a specific project can cause too much overhead if there is no effort to customize the given generic processes. Even though the customizing activities are done before starting the project, these activities are thoroughly dependent on the process engineers who have abundant experience and knowledge with tailoring processes. Owing to this dependence on human knowledge, it has been very difficult to explain the rationale for the results of process tailoring and it takes a long time to get the customized process that is applicable. Hence, we suggest a process tailoring method which adopts the artificial neural network based teaming theory to reduce the time consumed by process tailoring. Furthermore, we suggest the feedback loop mechanism to get higher accuracy in the neural network designed for the process tailoring. It can be done by reusing the process tailoring data results and determining its appropriateness level as sample data to the neural network. We proved the effectiveness of our process tailoring method through case studies using real historical data, which yielded abundant process tailoring results as sample data.

Living Lab is being introduced and applied as an innovation model driven by social entities (residents, users, etc.) and as an innovation place based on local and field. This study analyzed three living lab cases of Bukchon IoT living lab, Seong-Daegol energy transition living lab, and Daejeon Geonneoyu project, which were designated as 'Living Lab' to solve local problems. We analyzed the local problem, the problem solving goal, the role of each participant and the subject, the living lab promotion system, the significance in each case. In addition, the types and characteristics of living labs were elucidated and future development plans were discussed. The result is as follow. First, each case has a tendency to link science technology and ICT with local problem solving though there is a difference between the technologies used. Second, local residents played a leading role in the whole living lab process from problem identification to technical experimentation, diffusion and application. Third, the role of the intermediaries commonly played an important role in the operation of the living lab. Last but not least, each case has different types of living lab. Bukchon IoT living lab being operated as a project by the government / municipality to create a living lab activity-base or to support actors' activities. On the other hand, the Seong-Daegol energy transition living lab and Daejeon Geonneoyu project were conducted by the civil society itself to define problems and explore technologies in order to solve local problems.

This study aims to analyze the environment for the open-source records system and to identify the risk and requirements for the success of the strategy in Korea. For this, Chapter 2 presented a review of the strategic benefits of open source to public organizations, developers, and users. It also discussed the process of cooperatively developing and releasing the source code and the technology infrastructure supporting open source. In Chapter 3, six representative open-source projects in the field of records management were selected, and case studies were conducted. To derive comprehensive implications, we have divided the main development body of open-source projects into international organizations, international cooperation systems, national archives, and software development companies. We also analyzed the background and purpose of each project, the agents of development and funding, the governance model, the development period and cost, the business model and software architecture, the community composition, and the licensing strategy. Through this, we have derived four critical success factors. In terms of technology, a component-based design was required; therefore, we proposed a microservice architecture and a model-view-controller design pattern. Next, it was necessary to reestablish system requirements of records center and archives. Moreover, we also proposed a dual licensing strategy to allow developers to easily participate in open-source projects. Lastly, we emphasized a strong governance structure and an effective cooperation framework to create a sustainable community. For a record system to be open-source successfully in an organization-centered market, the roles of software developers and end users should be exercised more in the community. To achieve this, it is important to build various collaborative tools and development infrastructure from a planning stage to a centralized one.

A software size estimation has to be analyzed in the beginning of the software life-cycle and helpful to the prediction of its size and cost. The software cost has been calculated by estimating software size from the user's point of view since the function point method based on international standards was introduced for the estimation of software size in 2004. However, the current function point method is not easy to be exploited for unfamiliar user, and has a problem that it cannot estimate the proper size for software such as engineering software, scientific calculations and simulation with complicated internal computational logic. This paper presents an improved model which can simplify the existing function point measurement procedure, and perform the estimation of software size in easy and fast way at the initial stage of project. Moreover, it presents a mathematical weighted value calculation model which can solve the problem of the fixed complexity weighted value and reflect the characteristics of organization as its data is pilled up. Our evaluation shows that the presented model has advantage that it can measure the size more rapidly than the existing FPA methods and has more correlation with LOC.

Majority of knowledge management(KM) studies in e-government have been confined to facilitate KM within an organization. But due to citizen-centric(citizen-driven) paradigm shift and advance of web 2.0 communication in recent years, KM between governments and citizen in e-government portals is becoming an important consideration. So a series of studies on knowledge enhanced e-government portal get under way by considering that it is necessary to enhance knowledge of e-government portal and assuming it improves the usability of portal. While the topics of knowledge enhancement and e-government(portal) are widely discussed in their own domains there is a paucity of studies that address these constructs in a joint context. This paper aims to propose conceptual framework of knowledge enhanced e-government portal through structuralization of theoretical discussion with holistic approach. This framework presents an evolutional path of knowledge enhanced e-government portal that consists of three phases and it will be used for realizing the knowledge enhanced portal project as a basic reference model.
