  2. Agenda • Media richness theory 介紹 • 論文研讀 • 參考文獻

  3. Media richness theory • 主要依變數:Information processing, communication effectiveness • 主要獨立變數:Uncertainty Equivocality

  4. Media richness theory • 應用領域:Communication, Marketing and Management Information Systems • Level of analysis : Group Organization

  5. Media richness theory • 理論說明: • Daft & Lengel(1984)首先提出資訊豐富度的概念(information richness theory) • Weick (1979)與Galbraith (1973)因探討媒體是否具有傳輸豐富資訊的能力,而有媒體豐富性理論的產生。故又稱為資訊豐富度理論(information richness theory)

  6. Media richness theory • The first assumption of this theory is that organizations process information to reduce uncertainty and equivocality(Daft and Lengel 1986). • Uncertainty : Defined by Galbraith (1977) • Equivocality : Ambiguity of the task

  7. Media richness theory • Equivocality is high • An individual does not know what questions to ask • Uncertainty is high • The group knows the question but lacks the necessary information • As information increases, uncertainty and equivocality decrease.

  8. Media richness theory • The second assumption of this theory is commonly used media in organizations works better for certain tasks than others • Daft and Lengel (1984)

  10. 論文研讀 • Message Equivocality, Media Selection, and Manager Performance: Implications for Information Systems,” MIS Quarterly (11:3), 1987, pp. 355-366. • Author: Daft, R. L., Lengel, R. H., and Trevino, L. K

  11. 研究發現(一) • 管理者在含糊不清的情況下,比較喜好豐富多樣化的媒體來做溝通。 • 相反地在明確不含糊的情形時,管理者比較會選擇單調的媒體來傳達意見。 • 高執行力的管理者對於訊息模糊和媒體豐富兩者間關係的敏感度比低執行力管理者更高。

  13. 研究發現(二) • 管理資訊系統和新的電子化溝通系統都面臨相似的問題,那就是年長的管理者未充分利用這些系統。 • 成功的系統與其使用於支援高階管理者決策制定,應該更欣然地運用在較低層級的運作上。

  14. 研究發現(三) • 儘管電信和電腦會議、電子郵件存在著,經營管理者仍花大部分的時間在傳統的面對面和團體溝通討論上。 • 研究結果顯示,對高級管理人員所作的決定,面對面的溝通具有特殊的能力。

  15. 研究發現(四) • 也許更重要的是,調查結果表明,高執行力的管理者有能力勝任溝通任務。 • 高執行力的管理者直覺了解到面對面溝通方式對鬆散的交流是需要的;書寫溝通方式對例行公事交流更有效果。

  16. 研究討論(一) • 由於媒體的特性決定了管理者對媒體的理解,應用新媒體時或許可以進行調整,以配合其能力,滿足豐富的通信需求。 • 電視會議較面對面溝通少了點豐富度,但比電話有更大的傳達資訊能力,而且回饋更快速。

  17. 研究討論(二) • 電話會議在語氣上來說比面對面溝通少了點感情,因此比較適合用來交換詳盡明確的資訊。 • 電子郵件和電話或者書面備忘錄,有許多相似的特徵,都能夠快速回饋和可以很快地達到廣泛的、在地理上分散。

  18. 研究結論(三) • 電腦訊息系統已經被發現,適合交換分離不連續的資訊。 • 電子化郵件被認為不適合用來交換機密的資訊、解決爭論、結識某人或者談判。
