本研究以探討協同及PLM為出發點，一方面對PLM目前的發展狀況進行討論，另一方面也對PLM核心協同的概念進行了討論。在了解PLM發展的現況及產品生命週期各環節間協同互動對於PLM的重要性後，本研究以Web 2.0的概念進一步探討其在PLM上的應用。 本研究以V-Model做為情境的探討，並用以分析PLM可加強之處。PLM在支援V-Model測試相關活動情境下，本研究歸納出三項可加強之處。第一，測試相關資料沒有一個共同存取的環境；第二，資訊傳達沒有效率且資訊本身無組織性，，並且使用者在訊息接收及瀏覽上也缺乏較為主動的能力；第三，各部門人員沒有可以共同發表意見的平台。 / This research starts with discussing collaboration and PLM. On one hand it discusses the current development of PLM, and on the other hand it discusses collaboration with is the key concept of PLM. After understanding with the current development of PLM and the importance of collaboration with each product life cycle site in PLM, this research uses the Web 2.0 concept to further discuss its application on PLM. This research uses V-Model to discuss the scenario and analyzes which point PLM can be improved. In the testing relative activities scenario of V-Model with PLM supporting, this research concludes three points which PLM can be improved. First, there is no unified accessing environment for testing relative data. Second, it is ineffective in transforming information and information is not innately organized, and the users have no active abilities to accept message and on browsing. Third, there is no unified platform for each department employees to offer opinions.
