Agile is a software development methodology which was established for four objectives; people, collaboration, responsiveness, and working software. Thus the Agile methodologies have been applied not only software development fields but also various special areas of technology. ESA (European Space Agency) adopt several Agile methodologies, including Scrum as the key technique, for the software development of ground segment. This article analyzes trends of Agile methodologies and introduction cases of the methodologies for ESA's ground segment software development.

Agile methodologies in software development, including the development of artificial intelligence software, have been widespread over the past several years. In spite of the popularity of agile methodologies in practice, there is a lack of empirical evidence to identify determinants of success of software projects in which agile methods are used. To understand the role of clients in software project where agile methods are used, we examine the effect of client-side factors, including lack of user involvement, unrealistic client expectations, and constant changes of requirements on project success from practitioners' perspective. Survey methods are used in this study. Data were collected by means of online survey to IT professionals who have experience with software development methodologies, and ordered logit regression is used to analyze the survey data. Results of our study imply the following managerial findings. First, user involvement is critical to project success to take advantage of agile methods. Second, it is interesting that, with an agile method, constant changes of client's requirements is not a negative factor but a positive factor of project success. Third, unrealistic client expectations do negatively affect project success even with agile methods.

소프트웨어 개발 환경의 급격한 변화와 지속적인 요구사항 변경으로 인해 발생하는 전통적 개발 방법론의 문제점을 해결하기 위한 애자일 개발방법론은 관심의 대상이 되었다. 비교적 짧은 주기를 가지고 요구사항 분석, 설계, 코딩, 테스트 과정을 끊임없이 반복하며 점차 소프트웨어의 규모를 늘려가는 애자일 개발방법은 오픈소스 소프트웨어의 개발방식(OSSDP)과 매우 유사하다고 볼 수 있다. 지금까지 애자일 방법론은 Scrum, XP, Lean, Crystal 방식 등 여러 가지 방법으로 시도 및 제안되고 있으며, 점차 다양한 프로젝트에서도 성공적으로 수행할 수 있도록 개선되고 있다. 이러한 애자일 개발방식의 특징을 OSSDP에 적용함으로써 더 많은 오픈소스 프로젝트가 성공할 수 있도록 하는 프로세스를 연구하는 것은 의미가 있다. 애자일 성명서에서 추구하는 4가지 가치인 소통, 단순성, 피드백, 용기를 반영한 관행(practice)을 OSSDP에 채택하여 추가할 경우, 사용자 만족도를 높이고 결과적으로 오픈소스 프로젝트 성숙도를 높이는데 기여할 것으로 기대한다.

The aim of the study is to combine software reuse with agile methods through reuse in the early stage of agile development. Although agile methods and software reuse have different practices and principles, these methods have common goals, such as reducing development time and costs and improving productivity. Both approaches are expected to serve as viable solutions to the demand for fast development or embracing requirement changes in the rapidly changing environments. In the present paper, we identify economical agile reuse and its type and study a reuse technique for input queue in Kanban board at the early stage of hybrid agile methods. Based on our results, we can integrate software reuse with agile methods by backlog factoring for input queue item in the hybrid Scrum and Kanban method. The proposed technique can be effectively applied to e-class applications and can reuse the input queue items, showing the combination of the two approaches. With this study, we intend to contribute to reuse in the early stage of agile development. In the future, we plan to develop a software tool for economical agile reuse.

Despite agile methods and software reuse being distinct approaches, there has been a growing amount of research on combining these approaches. Although Scrum is one of the most popular agile methods, reuse has not been actively supported. In this paper, we identify a new type of reusable Scrum assets, simplify the backlog process and propose a backlog factoring technique by extending task factoring to support reuse in the Scrum method. In addition, we can apply the proposed technique and show prototyping of backlog reuse in e-business applications.

The Agile movement is a phenomenon that is part of the next phase of the software engineering evolution. At the same time, globally distributed software development is another trend delivering high-quality software to global users at lower costs. In this paper, Agile Framework for Distributed Software Development (AFDSD) has been suggested, and Chameleon project of Yahoo! Inc. has been implemented based on the framework. Also, the project has been evaluated by measuring Agile adoption and improvement levels, degrees of agility and agile project success, and comparing the performance and quality with the previous version. The overall performance and satisfaction with Chameleon increased by more than 30% since Agile techniques were adopted. Our objective is to highlight successful practices and suggest a framework to support adoption and evaluation of Agile techniques in a distributed environment.

Agile software development methodology is a lightweight software development method, plays an important role in the software development team. In this paper, we propose programs that in when agile development co-operation, team management, team collaboration and project management tasks can be high efficiency and allocation of human resources. The proposed model, the use of 6-Sigma priority assignment, established a mathematical model of the operation and distribution of human resources is the most reasonable people go to work. Cooperation makes team-based agile development can improve efficiency. This method improve staff efficiency by teamwork to improve the productivity of software development.

There has been a growing amount of research on combining Agile methods and software reuse. Most of it introduces Agile into software product line rather than software reuse into Scrum method. Meanwhile, some assets such as backlogs and incremental artifacts in Scrum development are reusable. In this paper, we identify a backlog binder that aggregates reusable Scrum assets and proposes a backlog binder reuse technique. In addition, we can apply the proposed technique and show prototyping of backlog binder reuse in job matching applications.

Since software reuse and agile development methods are seen as ways to shorten development time and accept frequent requirement changes, respectively, there has been growing interest and research on integrating these approaches. But despite the increasing number of software companies which have successfully adopted agile development methods, there has been little research on reuse in agile methods to further improve productivity. In this paper, we identify a new type of reuse asset and propose a task factoring technique by taking advantage of iteration characteristics to support reuse in agile software development methods. In addition, we can apply the proposed technique and show prototyping of task reuse in a video rental application.

소프트웨어 개발은 협업이 가장 중요시 되는 분야 중 하나로 팀 단위의 소프트웨어 개발의 품질 및 생산성 향상을 위해 팀 단위 프로젝트 방법론이 발달하였다. 방법론의 선택에 따라 개발의 결과물과 만족도에 큰 차이가 나타나게 되는데, 고전적인 폭포수(Waterfall) 방식의 대안인 애자일(Agile) 방법론은 점진적인 개발로 프로젝트 진행도중 발생하는 이슈처리를 효율적으로 해결할 수 있어 현재 많은 개발에 적용되고 있다. 그 중 스프린트 기법을 바탕에 두는 스크럼(Scrum)을 사용하는데 소규모 개발팀은 스크럼(Scurm)의 교육 부담과 스크럼 마스터의 부재로 해당 방법론을 적용하기 어려움을 겪는다. 이에 본 논문에서는 소프트웨어 공학의 애자일(Agile) 방법론 중 하나인 스크럼(Scrum)을 실제 프로젝트 관리 시스템의 도구로 사용하기 위해 웹 응용 시스템으로 구현하고자 하며 해당 서비스가 SW개발뿐 만 아닌 다양한 분야의 프로젝트에 적용될 수 있도록 한다. Spring 프레임워크를 이용하여 서버를 구축하고 AWS EC2를 통해 배포하며, BootStrap과 JQuery를 이용하여 웹을 구성하여 팀 프로젝트에 있어 효율적인 관리 도구가 될 수 있도록 한다.
