在強調競爭策略的今日，品質已成為企業成功的關鍵。ISO 9000仍推行以來廣受世界各國重視，許多文獻大都偏重於製造業ISO認證活動之研究，缺乏服務業方面的實證，而推行ISO對組織行為的影響更是付諸闕如。在相關研究中，學者主要針對組織變革、對組織氣候以及組織承諾等議題從事研究，且大多僅止於單一時間點橫斷面分析，鮮少從事縱斷面的研究。本研究以跨時點模型(Two-Wave Model)，探討實施ISO制度對組織氣候變化之影響，以彌補學理上在縱斷面實證研究的不足。研究結果發現:實施ISO制度確實對整體組織氣候認知的變化產生顯著影響，其中不同教育程度、管理階層、性別以及年資都會對ISO制度的推行產生不同的認知，因此組織氣候的認知也具顯著的變化。從管理的觀點，推行ISO制度必須考慮組織內成員的反應，例如透過不同的輔導以及宣傳策略以利新制度的推動。
