The effect of task–individual–technology fit on user attitude and performance: An experimental investigation
Highlights
► Task-technology-individual fit model is deconstructed into three two-way dimensions. ► Performance consists of two components; technology performance and task performance. ► User attitudes are affected by fit between individual and technology. ► Technology performance is a function of user attitude and fit. ► Task performance is a function of user attitude and technology performance.
Introduction
This paper uses a well established model [23] to frame an in-depth investigation of the effects of fit on decision support outcomes. Goodhue and Thompsons' [23] task–technology–individual fit model is deconstructed into three two-way interactions, task–technology fit (TTF), individual–technology fit (ITeF), and task–individual fit (TaIF) after Liu et al. [34]. The degree of granularity obtained by using this deconstructed model creates an opportunity to address fundamental decision support questions from a fresh perspective.
DSS performance is contextualized into two dimensions. One relates to the use of the DSS to obtain a better outcome or recommendation from the technology (technology performance), the other relates to performance on the decision task (task performance). Technology performance is about using the system; task performance is about using the outputs of the system. Prior empirical evidence demonstrates that improved technology performance leads to improved task performance [26], [50]. This relationship is not necessarily direct given that a user could use the system but not rely on the information it provides, in which case the DSS would affect technology performance but not task performance. Alternatively, a user could elect to use the system and to rely on the outputs, affecting both technology performance and task performance.
If technology performance is a necessary, but not sufficient, condition for improved task performance other questions arise. What prompts users of DSS to reply on DSS outputs? Under what conditions does technology performance affect task performance? The answer appears to lie in the attitude of users towards the DSS, with many prior studies linking users' attitude to technology with their performance. [18], [19], [23], [29], [31], [34]. In particular, the consideration of users' beliefs and attitude is particularly important where the use of the DSS is not mandated, and where the task solution is non-normative [27]. This paper looks at the impact of fit and user attitude on performance, exploring both technology and task performance. The primary research question addressed is:
How do task–technology–individual fit affect DSS user attitude and performance?
The remainder of the paper is organized as follows. The research background and theoretical foundations for the work are presented in Section 2. Section 3 details the specific hypotheses while Section 4 discusses the methods and materials used to test these hypotheses. Results are presented in 5 Results, 6 Discussion and conclusion contains a discussion of the results and limitations, and concludes the study.

Considerations of fit, user attitude and performance
Conceptually achieving “fit” is about aligning the interrelationships between individuals, tasks and technologies. Existing studies recognize that fit affects both user attitude and performance [10], [23], [34], [53]. The task–technology fit model [23] suggests that performance depends on fit, identifying a weakly positive link between usage and performance. Recent work by Liu et al. [34] explored task–technology–individual fit by employing three differing fit interactions
Hypotheses
The three two-way fit interactions involving the task technology and individual characteristic discussed in Section 2 are examined in this section by considering direct effects of individual fit dimensions, and by examining relationships between fit, user attitude and performance as shown in the research model contained in Fig. 1.
Experimental task and context
The context of this study is a non-normative judgment task that requires subjects to make a recommendation about the future of a company that has recently entered into voluntary administration. The task was framed within relevant corporate insolvency legislation. Subjects were cast as a voluntary administrator making a recommendation about the future of a company; they had to decide whether to allow the business to continue to trade or to close the business down and sell off the assets. The
Results
All hypotheses were tested using ANCOVA/MANCOVA techniques to appropriately identify variations between groups [47]. Separate MANCOVA analyses were conducted to test Hypothesis 1, Hypothesis 2, Hypothesis 3. The detailed results contained in Table 7 support all three hypothesized relationships. As expected, fit between the technology and the user (ITeF) significantly affects user attitude towards the technology, after controlling for their unaided performance and decision agreement. Support for
Fit and user attitude
When a technology is designed to fit the level of an individual's expertise (ITeF), the individual's attitude towards the technology is directly affected. By contrast, when a technology is designed to fit the complexity of a task, technology performance is directly affected. These results are important as they reinforce the desirability of fitting technology design to a task rather than an individual where a DSS is intended to improve performance rather than attitude.
