因為通訊科技的進步，人與人間地的溝通也更加的方便，但在高動態的工作環境中，行動工作者所面臨的環境不斷的在改變，
所接受的訊息也更加的多樣化，對行動工作者而言，資訊超載(information overload) 已是一個普遍的現象，愈需要使用網路的人，
就愈能感受到資訊多到難以消化。接受不需要的訊息，容易降低工作效率，甚至是中斷任務。
本研究就是為了解決上述問題而導入ARCI模式與WBS讓這些行動工作者有效率的協同運作達到行動工作者的有效管理。
Communication between human beings has been dramatically changed due to the development of information technologies and telecommunication technologies. Unfortunately, the evolving of the highly dynamical working environment, people, who works in a so-called mobile office,must receive massive and varied data, messages or information.Information overload seems unavoidable. More Internet usages, more information to consume.
Unlike traditionally speaking,knowledge/information is power. Nowadays, receiving data may not only be a benefit, but also a heavily cost to our daily life and work. In this paper, a new approach based on work breakdown structure and information authority matrix is proposed and a web-based prototype is built to evaluate its performance. In the proposed mechanism, it is believed that message passing within the environment is rapidly reduced without compromising the communication chain.
