Valid measurement scales for predicting user acceptance of computers are in short supply. Most subjective measures used in practice are unvalidated, and their relationship to system usage is unknown. The present research develops and validates new scales for two specific variables, perceived usefulness and perceived ease of use, which are hypothesized to be fundamental determinants of user acceptance. Definitions of these two variables were used to develop scale items that were pretested for content validity and then tested for reliability and construct validity in two studies involving a total of 152 users and four application programs. The measures were refined and streamlined, resulting in two six-item scales with reliabilities of .98 for usefulness and .94 for ease of use. The scales exhibited hgih convergent, discriminant, and factorial validity. Perceived usefulness was significnatly correlated with both self-reported current usage r = .63, Study 1) and self-predicted future usage r = .85, Study 2). Perceived ease of use was also significantly correlated with current usage r = .45, Study 1) and future usage r = .59, Study 2). In both studies, usefulness had a signficnatly greater correaltion with usage behavior than did ease of use. Regression analyses suggest that perceived ease of use may actually be a causal antecdent to perceived usefulness, as opposed to a parallel, direct determinant of system usage. Implications are drawn for future research on user acceptance.

Agility is vital to the innovation and competitive performance of firms in contemporary business environments. Firms are increasingly relying on information technologies, including process, knowledge, and communication technologies, to enhance their agility. The purpose of this paper is to broaden understanding about the strategic role of IT by examining the nomological network of influences through which IT impacts firm performance. By drawing upon recent thinking in the strategy, entrepreneurship, and IT management literatures, this paper uses a multitheoretic lens to argue that information technology investments and capabilities influence firm performance through three significant organizational capabilities (agility, digital options, and entrepreneurial alertness) and strategic processes (capability-building, entrepreneurial action, and coevolutionary adaptation). We also propose that these dynamic capabilities and strategic processes impact the ability of firms to launch many and varied competitive actions and that, in turn, these competitive actions are a significant antecedent of firm performance. Through our theorizing, we draw attention to a significant and reframed role of IT as a digital options generator in contemporary firms.

The study sought to examine the influence of information technology skills on performance of Tea Producers companies in Kenya. The study reviewed theoretical and empirical literature relevant to the role of Information Technology skills on performance of Tea Producers companies in Kenya. The conceptual framework was discussed to show the relationship between Information Technology skills and firm performance (dependent variable). Positivism philosophy guided this study. Positivism philosophy emphasizes the importance of empirical evidence and scientific methods in understanding the world and acquiring knowledge. The study used cross-sectional survey design to establish the role of Information Technology strategic alignment on performance of Tea Producers companies in Kenya. In this study, the target population was identified as tea producer companies that are members of the East Africa Tea Trade Association (EATTA) in Kenya. This choice was made on the premise that these entities are likely to possess pertinent and accurate information relevant to the research. Specifically, the population encompassed all 29 tea producer members of EATTA. Respondents’ population comprised of six top managers from each organization translating to 174 top managers. The sample size was 121 top managers. They were targeted because top managers of organizations mostly handle strategic management issues. The research employed purposive sampling to select respondents and primarily relied on gathering primary data. A questionnaire with a diverse set of questions was utilized to collect responses from participants. Prior to the main study, a pilot study was conducted to ensure the validity and reliability of the questionnaire. The findings of the study indicate that information technology skills exert a positive and statistically significant influence on the performance of tea producer companies in Kenya. Findings revealed that cross-training, encouraging innovation and providing employment opportunities influences performance of Tea Producers companies in Kenya. This implies that a unit improvement in information technology skills would lead to improvement in performance of Tea Producers companies in Kenya. Based on the findings, this study recommends that the management of tea Producer companies should formulate and implement effect employee training programs to improve their IT skills.
