6 Usual Quality Activities 일반적으로품질과관련된업무는개발자가코딩을끝내는시점에시작되며, 대부분품질과관련된노력은이이후에집중된다. Analyst Architect Developer Tester Operation Define Design Code Test Debug Functional Test Load Test Deploy Monitor 품질과관련된첫업무시작시점 대부분의노력을투입하는시점 품질은다양한측면에서요구사항에맞는최종산출물을의미 대부분의경우주어진요구사항에맞추어품질에대한검증이시작되며, 잘못분석된요구사항에대한검증은이루어지지않음 품질은 QA 팀에서관리하는것으로인식하는경우가많으며이방법으로는대부분 deploy 직전에문제를발견
