The methodology for maintenance system development should overall be considered with all of task characteristic, schedule, and the technical condition of investment sources. This research applies Waterfall model to methodology for the development and construction of maintenance system through customizing the CD (Custom Development) procedure of "HSDM (Hyundai System Development Methodology)" based on information engineering. The waterfall model called as classic life cycle paradigm is defined for the sequent development procedure, which make progress a next step after that a previous step is admitted with thorough review. This model which is popular and the oldest paradigm is used for system development by four steps; demands analysis, design, construction, and maintenance. This methodology advances higher abstract step from higher lower step using top-down approach from concept definition to construction, which notices the end of a step whenever a step is over. Therefore, each step is exactly divided, and consequently the output is clearly yielded.

Estimating optimum hardware capacity of an e-learning system is very important process to grasp reasonable size of designing technique architecture and budget during step of ISP(information strategic planning) and development. It hugely influences cost and quality of the whole project. While investment on information system hardware has been continuously increased, there was no certified hardware capacity estimating method in e-learning system development. A guideline for hardware sizing of information systems was established by Telecommunication Technology Association in 2008. However, the guideline is not appropriate for estimating optimum hardware capacity of an e-learning system because it was designed to provide general standards for estimating hardware capacity of various types of projects. The purpose of this paper is to provide a methodology for estimating optimum hardware capacity in e-learning system development. To develop the methodology, this study, first of all, analyzes two e-learning development projects, in which the guideline was applied to estimate optimum hardware capacity. Then, this study finds out several key factors influencing on hardware capacity. Finally, this study suggests a methodology for estimating optimum hardware capacity of an e-learning system, in which weights for the factors are determined through AHP analysis.

The purpose of this study is to assess and develop effective MIS planning method by applying the CSF method. With the comparative analysis of the Rockart's basic concept of CSF and the examples of the corporations which employed CSF methodology, a new CSF method more suitable to Korean business environment is proposed and applied to another company for evaluation. The new CSF methodology consists of three steps. The first step is to preexamine the business conditions. The second step contains an Introductory Workshop, interview with the managers, survey questionnaire, Focusing Workshop, and decision of the priorities for system development. The third step is a real development of an information system out of the first and second steps. As a result of this study, it is found that revised CSF method can induce top management to participate more in the activities of information system development and that it can make top management to focus on the critical area. The fulfillment of the information requirement out of the enhanced MIS planning will lead to more successful management activities.

소프트웨어개발방법론은 급변하는 정보기술변화에 따라가지 못한다. 대부분의 소프트웨어 개발 프로젝트는 구조적 또는 정보공학 방법론을 사용한다. 기존 소프트웨어 개발 방법론이 프로젝트에 적용할 기술이 반영이 안되어 있다면, 프로젝트는 비효율적으로 수행되어진다. 본 논문은 새로운 정보기술을 기존의 구조적 또는 정보공학 방법론에 용이하게 반영하여 개선하는 모델을 제안한다. 본 모델은 소프트웨어 생명주기를 단계들로 나누고 각 단계는 관점 영역으로 나누어 분할된 작은 영역에 새로 적용할 정보기술을 반영하는 분할과 정복 기법을 활용한다. 적용사례는 설계단계를 중심으로 KCC 정보통신(주)에서 사용한 클라이언트 서버 방법론 CS@RoadMap에 웹 기반 소프트웨어 개발절차를 반영하였다. CS@RoadMap방법론에 웹 기술을 반영한 Web@RoadMap방법론을 공공 프로젝트에 적용하였다.

We propose the specialized product-line development methodology for developing the embedded system of an MSDFS (Multi Sensor Data Fusion System : called MSDFS). The product-line methodology provides a simultaneous design between software and hardware, high level reusability. However this is insufficient in requirement analysis stage due to be focused on software architecture, detailed design and code. Thus we apply the business model based on IDEF0 technique to traditional methodology. In this paper, we describe the processes of developing Core-Asset, which are requirement analysis, feature modeling, validation. The proposed model gives the efficient result for eliciting features, and ensures the high level reusability of modules performing on embedded system.

우리나라 농촌의 발전전략중 하나인 정밀과학 기술농업실현을 위해서는 작물별 통합기술정보시스템이 필요하다. 이 시스템은 웹 기반으로 작물생산자와 기술조언자를 위한 협업시스템이어야 하며, 실시간 정보 분석 및 지식제공이 가능하여야 한다. 본 논문에서는 상기 특성과 농업 분야 작물생산정보시스템이라는 특징을 가지고 이를 지원하는 작물 컴포넌트 등의 개발을 위한 방법론을 만들었다. 특별히 기존의 대단위 프로젝트에 적합한 마르미-III 방법론을 작물생산정보시스템을 위한 컴포넌트의 개발 특성에 적합하게 재조직화 하여 MCPI(Method for Crop Production Information system)를 제시하였다. 또한 현실문제의 적용가능성을 파악하기 위하여 MCPI에 기초하여 작물생산정보시스템 컴포넌트의 프로토타입을 개발하고 평가하였다. 평가결과 타 방법론과 비교하여 농작물분야에 최적화된 단위 컴포넌트 개발방법론이라는 것을 확인하였으며 비교결과를 논문에 기술하였다.

There are many limitations in applying agile methodology to projects so far. In fact, projects overlap with other development methodologies and management processes, resulting in confusing progress, while there are often cases where the benefits of agile cannot be embraced due to a lack of understanding of agile processes and the organization's inability to adapt to change. It is an important role of information system development to improve the quality of agile application projects by discovering the problems and improvements in these cases. In this paper, we analyze the differences between existing development and project management methods and agile, and analyze agile processes. The optimal agile methodology was proposed by analyzing and applying methodologies established and applied mainly by large domestic development companies. In addition, the effectiveness was verified through a questionnaire of IT experts, and the result of the questionnaire was verified to be 4.75 points on a 5-point scale.

Our study focuses on the implementation of IS development methodology as the innovation of IS organization. We have two main research objectives. We Intend to understand the critical factors affecting the implementation process of IS methodology. We also intend to deeply analyze the relationship among the implementation processes of methodology. The whole innovation process is divided into detailed four levels tilth dynamic and evolving Point of clew a cognition level, an adoption level, an acceptance level and an usage level. The results of our study are as follows. The main factors affecting initiation level of the IS methodology are the innovativeness of IS members, the existence of champion manager, training, the existence of IS performance gap, executive supports for IS organization, and the relative advantage of IS development methodology At the Implementation level, It is understood that the existence of champion manager executive supports, training and the relative advantage of innovation are the main factors. However, the complexity of Innovation is a megative factor about the quality of accepting and using the methodology In Innovation process. In performing the Innovation process, the Previous level gives very notable affection to the continuous next level. However it's also understood that positive attitude of adoption level does not directly affect the quality of using Innovation. Therefore, IS managers must pay attention to manacle each level of the Innovation Process to successfully accomplish the Implementation of IS methodology.

소프트웨어의 개발 방법은 환경의 변화에 따라 계속해서 발전되었다. 구조적 방법론, 정보공학 방법론 그리고 객체지향 방법론이 이런 변화의 큰 흐름이다. 각 방법론은 특징과 장점이 있고, 적용되는 분야가 다르다. 실무를 수행하는 엔지니어들은 각 방법론을 적용하는 것은 익숙하지만, 구조적 방법론이나 정보공학 방법론을 통합하여 적용하는 것에 익숙하지 않다. 그래서 방법론이 가지는 효과를 최대한 얻을 수 없다. 이런 점에 착안하여 각 방법론의 적용 대상에 대해 구조적 방법론, 정보공학 방법론을 통합하여 적용하는 방법에 대한 것을 정리하고 사례를 제시하고자 한다.

USM(Unit Service Management System) is the development tool and methodology to handling the event process in a U-City integrated platform by using the minimum unit services. USM can be one of the SOA development methodology. Minimum unit service has a minimum business logic that can be executed with input and output parameters. Minimum unit service consists of three parts : service profile, service input and output parameters and service execution information. USM provides two types of the execution method. One is module execution and the other is web service execution. The development of the event sinario by the USM development methodology can reduce the cost and duration of the u-service development by raising the rate of reusing minimum unit service.
