4 우리회사의 핵심 경쟁력? Confidential 우리 회사는 자동차 부품에 관련된 전자, 전기 부품을 생산하는 글로벌 선두기업으로 혁신적인 전략으로 세계시장을 리드하고 있습니다. <중략> 현재 우리 회사의 경영진은 소프트웨어의 생산 효율성과 품질에 대해 많은 관심과 우려를 가지고 있습니다. 우리는 다음과 같은 소프트웨어와 하드웨어의 문제점을 해결하기 위해 <중략> 임베디드 SW 크기와 복잡도 증가에 따른 비즈니스의 영향 품질관리의 문제와 통합, 테스트 작업의 지나친 시간의 손실 많은 공급업체가 공급한 많은 컴포넌트 간의 통합과 호환성 문제 경쟁시장에서의 선점적 출시 압박해결을 위한 생산성 수없이 많은 Embedded SW, HW의 환경변화에 대한 유연한 대응 A group of us at the former Rational Software Corporation sat down to write a paper on the issues of developing solutions using a service-oriented architecture (SOA) style, 1 and a lot has happened since then. One of the problems we faced was that Rational Software had a set of modeling tools, but no IDE to actually develop the service implementations we modeled. Well, with the acquisition of Rational by IBM, we now have a world-class IDE in the form of the WebSphere Studio Application Developer (now Rational Application Developer, or RAD). We also faced the problem that a lot of thinking around SOA was immature, and much was hype-driven -- a problem we recognized in the paper. Since IBM's platform support for SOA has matured considerably and our developer tools have increased their capabilities for developing services in a flexible and rapid manner, we decided to revisit the notions of service design that we outlined in that earlier paper. The asset-based development process has been applied to Company IT, started in This has produced a 30% productivity improvement in their application development projects that have used it. Company IT applied some of the techniques described in the pilot project we are proposing. The specific items Company IT has done will be identified throughout these charts. Company IT conducted a pilot project for about 5 months before rolling out to other projects. In recent months Company IT has rolled out their assets and process across all their application development projects. They are now taking new measurements across the company. Anticipated benefits for Company IT from reuse strategy Increased productivity Improved quality Motivations for Company IT to pursue a reuse Similar reference architecture for all projects strategy Improved maintainability due to better separation of concerns Developers start from scratch each Better time consistency and traceability between specifications and code. Analysis and design models are Improved not consistent portability with code. Quality by really designing the system - Not only code hacking Architecture of current applications often makes it hard and difficult to perform changes for new business requirements 4

7 해결해야 할 문제점과 도전과제들 제대로 된 아키텍처만 구성하는데도 3년 이상이 걸렸다. 컴포넌트 기반 아키텍처가 과연 우리 도메인 (테크니컬 부분, 금융, 공공 등)에 적합할까? Componentization? 정의는? 어떻게 관리하고 배포하는가? 임베디드 환경에서 HW와 SW 과연 어떻게 통합할 것인가? 재사용, 소스 복사해서 쓰면 안 되는 것 인가? 과연 아키텍처, SW와 HW의 통합, 재사용 이러한 솔루션을 리드할 신뢰할 수 있는 Guru가 존재할까? 7
