隨著網路的無遠弗屆，及科技高速的發展之下，數位能力儼然已成為企業競爭的基礎能力，企業不斷的增加對於新興科技系統的投資，然而科技的使用或許能帶來更高任務成果效益，但同時也可能造成員工更大的心理壓力。先前相關研究多著重於科技如何協助任務的執行，本研究加入了個人心理因素來探討工作場域上影響任務與科技，以更完整的角度探討影響任務與科技適配之因素與其如何影響任務結果滿意度。
本研究結合了認知負荷理論、任務科技適配理論以及過去文獻中提及的架構來探討個人認知負荷對於任務結果滿意度之影響因素。任務科技適配受任務特徵、科技特徵所影響，本研究歸納出四項影響任務特徵之性質、與三項影響科技特徵之性質，並加入三項認知負荷因素來探討其對於任務科技適配程度之影響程度，而任務科技適配則影響任務執行過程滿意度，進而影響結果滿意度。
本研究回收了385份有效問卷，驗證任務特徵、科技特徵、認知負荷對於任務科技適配之影響，結果顯示時間壓力對於任務特徵無顯著影響，並表示支持個人認知負荷過載時對於任務科技適配的程度有負向影響，任務科技適配對於任務過程滿意度有顯著正向影響。本研究有別於以往任務科技適配之研究，結合認知心理學與架構來驗證影響任務適配之變數，可以提供給企業作為未來在科技評估或是流程改良之參考。

With the far-reaching characteristics of Internet, and the rapid development of technology, digital capabilities have become the foundation of enterprise competitiveness. Therefore, enterprises are constantly increasing their investment in emerging information system. However, while powerful technologies may bring higher task performances, it may cause serious psychological stress to employees at the same time. Previous studies have focused on how technology can be adapted to the task to achieve higher benefits. This study adds individual psychological factors to examine how these factors affect the degree of task and technology in the workspace.
This study combines Cognitive Load Theory, Task-Technology Fit Theory and the framework proposed in past literature to discuss the influence of cognitive load on task-technology fit. This study summarizes four task characteristics and three technology characteristics that affect task-technology fit. In addition, three cognitive load factors were added to the discussion. Task-technology fit affects the satisfaction of task process, which in turn affects the satisfaction of task outcome.
This study collected 385 valid samples. The results showed that time pressure didn’t have a significant effect on task characteristics, and indicated that cognitive overload had a significant negative effect on task-technology fit. This research differs from previous research by combining cognitive psychology to verify the variables affecting task-technology fit, which can be used as a reference for companies evaluate technology and improve process in the future.
