  1. The Model Underlying the Measurement of the Impacts of the IIC on the End-Users 作者: DALE GOODHUE 來源: JOURNAL OF THE AMERICAN SOCIETY FOR INFORMATION SCIENCE, 1997, 48, 5, 449-453 報告者:淡江大學資訊管理系碩士班1年級 600630510 黃俊達 600631112 林岡立 日期:2011/10/7

  2. 大綱 • The Model • Definition of Task-Technology Fit • Determinants of Task-Technology Fit • Utilization of Technologies • Determinants of Technology Utilization • The Link between Task-Technology Fit and Utilization • Performance • Feedback • Methods Employed for Impact Assessment

  3. Task-technology fit 任務-技術適合度理論 • TTF 提出者 Goodhue and Thompson(1995) • 若資訊科技要能有效提升個人工作績效，此技術必須被使用者接受且願意使用，並對其所支援的任務有相當好的配合度。換句話說，唯有使用者在所使用的技術能夠支援其要完成的任務時，才有可能出現良好的工作績效。

  4. Definition of Task–Technology Fit • Is defined as the degree to which a technology assists an individual in performing his or her portfolio of tasks. • 科技協助個人完成某些任務的程度.

  5. Determinants of Task–Technology Fit • Task characteristics • 工作特性是指工作有關的因素或屬性 • Individual characteristics • 使用者特性的不同 • Technology characteristics • 科技視為個人用來完成任務的工具

  6. Utilization of Technologies • An intervening variable between technology characteristics and individual performance • As Trice and Treacy (1988) suggest, as a necessary but not sufficient condition for technologies to result in improved performance.

  7. Determinants of Technology Utilization • Value of the increment in performance. • However, human behavior is not necessarily so rational.

  8. The Link between Task–Technology Fitand Utilization • The consequences of using a technology.

  9. Performance • Is the accomplishment of a task, or a portfolio of tasks, by an individual. • ‘‘Task–technology fit’’ affects individual performance • beyond its influence in promoting utilization. • 績效表現會同時受到任務－科技配適度以及使用行為的影響.

  10. Feedback • 使用技術的真實經驗會引導使用者會有更好的績效，進而影響未來使用. • 個人也許會從使用技術的經驗去學習. • 回饋在管理上的意涵即是管理者可以根據技術對績效的影響，可決定 • (1)中斷或重新設計技術 • (2)選擇訓練課程去提昇使用者的能力 • (3)重新設計任務

  11. Methods Employed for Impact Assessment • Two methods: • a survey of the target population and a reasonable control group of faculty. • a set of in-depth interviews of a smaller, carefully selected group of faculty. • The advantages of multiple evaluation methods are that different sources of evidence provide different views and thus can lead to different insights in an approach called triangulation.
