本研究動機是希望透過Web 2.0服務以善用集體智慧，目的在建立一個Web2.0服務發展的管理架構。從文獻中，我們整理Web2.0服務發展的特性，發現共創者和訪客的取得是經營Web2.0服務最重要的任務。根據印象管理理論以及臉書和維基百科兩個Web2.0服務發展過程，這項研究提出了一個四階段的Web 2.0服務發展生命週期。這四個階段依序是：模式確立、創新傳播、社群擴展和服務再造。除此之外，針對每一個階段，這項研究提出四個管理面向。這四個管理面向是：共創者管理、內容管理、控制管理和動態能力管理。接著我們深入探討台灣六個Web2.0服務的案例—玩運彩、愛評網、地圖日記、愛合購、MyGo和WEnews，進一步驗證我們提出的管理架構，並且豐富我們對Web2.0服務發展生命周期的認識。透過對於Web2.0服務發展生命週期的深入探討，期許研究成果能提供給Web 2.0服務管理者做為在管理上的參考依據。 / This study is motivated by the prospect of harvesting the collective intelligence of the Internet via Web 2.0 services and aims at building a framework for the management of Web 2.0 services development. By reviewing specific features of Web 2.0 services, we identify the acquisition of co-creators and viewers as the most influential task of Web 2.0 service development. Based on impression management theory and two typical Web 2.0 cases—Facebook and Wikipedia—we distinguish four phases of co-creator and viewer development throughout the life cycle of Web 2.0 services. The four phases are: model establishment, innovation dispersion, community expansion, and service re-invention. Besides, we also identify four dimensions of the management of Web 2.0 services development. The four dimensions are: co-creator, content, control, and dynamic capability. The four phases and the four management dimensions of Web 2.0 service development life cycle are then validated by industry experts and enriched by six Taiwan Web 2.0 service cases—PlaySport, iPeen, AnswerBox, ihergo, MyGo and WEnews. It is hoped that the elaboration of the life cycle of Web 2.0 services development can provide strategic input into the management of Web 2.0 services.
