在這個全球日趨複雜的商業競爭時代中，企業所面臨的最大挑戰是如何藉由洞悉創新的本質使企業競爭能力產生差異化，而可以更專業、精確與敏捷地迅速反應不同的市場需求，而順利地從眾多的競爭者在需求快速變化的市場中脫穎而出。許多文獻與調查報告均指出雲端運算提供了適切的解決方案。雲端運算可以支援企業對巨量的商業資料進行高效率且快速的運算結果，使企業可以在短時間內獲得精確且多樣的商業智慧，使企業可以成功地在商業市場的競爭中獲取利益。尤其，雲端運算提供了一個全新且經濟有效的運作模式，企業無需投資大量資金在資訊設備的採購與維護上，而是以實際的資訊運算需求進行付費。雲端運算改變了對資訊設備應用的傳統思維，提供全球企業一個絕佳的競爭機會。
為了驗證專業的雲端運算服務公司所提供的雲端服務是否具備實際的效益，本研究參考以往學者所發現的研究結果，並基於資源基礎理論，提出一個理論模式探討雲端服務、資訊技術能力與組織的敏捷性三者之間的關係，並藉由實證研究方法進行市場的調查與分析，並在台灣地區針對服務業與製造業，以問卷回收了133份有效樣本。研究結果顯示企業付費使用雲端服務將可以提高企業在市場操作上的敏捷性，以及企業的資訊技術能力會影響雲端服務的採用程度。本研究也發現，資訊安全並不會影響企業對雲端服務的採用程度；此悖論所產生的原因可以解釋為: 由於目前仍在雲端運算服務的發展初期，企業並未具備充份的信心將公司內部的運作程式與資料存放於雲端上，因此資訊安全的議題不會造成企業採用雲端服務的困擾。正如預期地，本研究也實證了企業的資訊能力對於組織的敏捷性具有顯著的相關性。
綜合本研究結果，企業必須不斷持續地扶植與發展更先進的資訊技術能力，使企業可以有效管理與利用資訊技術資源，方能增強雲端服務的採用效益，並進而建立一個充份具備敏捷性的組織。本論文結果希望能激勵更多的研究與討論，使能更全面地洞悉與掌握有關資訊技術能力、雲端服務導入與組織敏捷性之間的相互關係。

In this sophisticated business world, it will be very challenging for organizations to find innovative insights differentiating themselves from their competitors and transform themselves to be more masterly, accurate and agiler in order to rapidly respond to various requirements in the changeable market. A lot of literatures and consultant reports suggested that cloud computing might be the solution. Cloud computing can support organizations with very powerful computing capability to analyze massive business data and get more precise and diverse business intelligences in a short time to help companies succeed in the business competition. Even more, cloud computing gives organization a new economic model, shifting from deploying and maintaining high-cost internal IT facilities and manpower by substantial investment to requesting a cloud computing service provider by paying per use. This new trend has changed the traditional thinking about capitalizing IT and brought great opportunities and challenges to the business world.
In order to find out the effectiveness of cloud computing services provided from vendors, this study proposed a theoretical model based on the resource-based theory and conducted an empirical research by a field survey of 133 organizations in Taiwan to disclose and clarify the relationships among cloud service adoption, IT capability and organizational agility. The results provided empirical evidence that cloud service adoption with paying for providers retained a positive impact on firm’s agility, and IT capability positively enhanced the cloud service adoption. This study also found the information security did not have joint effect with IT capability on the cloud service adoption. This contradiction might be caused by the fact that internal functions and data of firms were not deployed on the cloud at this early stage of cloud evolution. As expected, we also revealed that IT capability is an essential factor to achieve organizational agility.
All these findings imply that firms need to continuously foster and develop advanced IT capability to successfully manage and leverage their IT resources to promote the effectiveness of cloud service adoption and to build agile organizations. We hope this study opens up further discussions and superb theory to generate a more holistic, comprehensive understanding about the contradictions and dynamics among cloud service adoption, IT capability and organizational agility.
