2 Agenda Quality & Who owns it? ClearQuest TestManager Test Management with a Single view Rational Performance Tester Bridging the gap between developers, testers & operation team Summary

3 Who owns quality? 소프트웨어개발프로젝트에서품질에책임을지고관련업무를수행하는사람은? 다음중소프트웨어개발프로젝트에서품질에책임을갖는사람을고르시오 ( ) 1. 테스터 2. 테스터와개발자 3. 테스터와개발자및프로젝트매니저 4. 팀원전체

4 Quality? 주어진요구사항을만족시킬수있는제품의기능과특성의무결성 (American Society for Quality) 요구사항에대한적합성 (Philip Crosby) 고객의기대치를충족시킬수있는제품과서비스의마케팅, 엔지니어링, 제조및유지보수등의종합적인특성 (Armand V. Feigenbaum) Fitness for use (Dr. Joseph M. Juran)

5 Usual Quality Activities 일반적으로품질과관련된업무는개발자가코딩을끝내는시점에시작되며, 대부분품질과관련된노력은이이후에집중된다. Analyst Architect Developer Tester Operation Define Design Code Test Debug Functional Test Load Test Deploy Monitor 품질과관련된첫업무시작시점 대부분의노력을투입하는시점?

6 Cost to find and fix problems 소프트웨어문제는실제환경에도입되어발생되었을때원인을파악하고해결하는데훨씬더많은시간과비용이소요된다. Cost to Repair Software - Cost of Lost Opportunities - Cost of Lost Customers Costs Development Phases

7 Continuously Ensure Quality 초기부터검증시작 자동화도구 개발, 테스트팀및운영팀간의협업 품질과관련된업무가시작되어야하는시점 일반적으로품질과관련된업무가시작되는시점 C O S T Iterative Process Business applications 변화하는 고객의 요구에빠르게대응 애플리케이션의 신뢰성확보 애플리케이션의 가용성확보를통한안정적운용 Continuously ensure quality to 고객의요구조건파악 의도된 대로소프트웨어가 작동하는지 검증 실환경도입후 애플리케이션이 제대로동작하는지 확인

8 Who owns quality? 소프트웨어개발프로젝트에서품질에책임을가지고있는사람은? Everybody 일반적으로품질은 Quality Assurance 혹은 Quality Control, Test, Quality Engineering 과같은이름으로불리는조직의특정한하나의팀혹은관련된인원이전담해야하는업무로인식 품질은프로젝트에참여하는전체인원이관여해야하는업무이며, 전체프로세스와업무를하나로통합해서생각할때성취될수있음 모든팀원이개발되는제품 ( 산출물 ) 과기반이되는프로세스의품질에참여하여이를개선하는노력을기울이는것이필요 품질관련노력 Analyst Architect Developer Tester Operation Define Design Code Test Debug Functional Test Load Test Deploy Monitor
