4 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。

5 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.

6 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

7 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.

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

9 The Link between Task–Technology Fit and Utilization
The consequences of using a technology.

10 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.

11 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

12 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.
