Prior research has provided valuable insights into how and why employees make a decision about the adoption and use of information technologies (ITs) in the workplace. From an organizational point of view, however, the more important issue is how managers make informed decisions about interventions that can lead to greater acceptance and effective utilization of IT. There is limited research in the IT implementation literature that deals with the role of interventions to aid such managerial decision making. Particularly, there is a need to understand how various interventions can influence the known determinants of IT adoption and use. To address this gap in the literature, we draw from the vast body of research on the technology acceptance model (TAM), particularly the work on the determinants of perceived usefulness and perceived ease of use, and: (i) develop a comprehensive nomological network (integrated model) of the determinants of individual level (IT) adoption and use; (ii) empirically test the proposed integrated model; and (iii) present a research agenda focused on potential pre- and postimplementation interventions that can enhance employees' adoption and use of IT. Our findings and research agenda have important implications for managerial decision making on IT implementation in organizations.

Technology Acceptance Model 3 and a Research Agenda on Interventions

Individualism and collectivism

While the technology acceptance model (TAM), introduced in 1986, continues to be the most widely applied theoretical model in the IS field, few previous efforts examined its accomplishments and limitations. This study traces TAM’s history, investigates its findings, and cautiously predicts its future trajectory. One hundred and one articles published by leading IS journals and conferences in the past eighteen years are examined and summarized. An openended survey of thirty-two leading IS researchers assisted in critically examining TAM and specifying future directions.

The Technology Acceptance Model: Past, Present, and Future

The authors examine the implications of electronic shopping for consumers, retailers, and manufacturers. They assume that near-term technological developments will offer consumers unparalleled opportunities to locate and compare product offerings. They examine these advantages as a function of typical consumer goals and the types of products and services being sought and offer conclusions regarding consumer incentives and disincentives to purchase through interactive home shopping vis-à-vis traditional retail formats. The authors discuss implications for industry structure as they pertain to competition among retailers, competition among manufacturers, and retailer-manufacturer relationships.

Interactive home shopping: Consumer, retailer, and manufacturer incentives to participate in

This article presents a critique of a number of shortcomings with the technology acceptance model (TAM) and points to specific remedies in each case. In addition, I present a model for the purposes of providing a foundation for a paradigm shift. The model consists first of a decision making core (goal desire → goal intention → action desire → action intention) that is grounded in basic decision making variables/processes of a universal nature. The decision core also contains a mechanism for self-regulation that moderates the effects of desires on intentions. Second, added to the decision making core are a number of causes and effects of decisions and self-regulatory reasoning, with the aim of introducing potential contingent, contextual nuances for understanding decision making. Many of the causal variables here are contained within TAM or its extensions; also considered are new variables grounded in emotional, group/social/cultural, and goal-directed behavior research.

The Legacy of the Technology Acceptance Model and a Proposal for a Paradigm Shift

This study investigates website quality factors, their relative importance in selecting the most preferred website, and the relationship between website preference and financial performance. DeLone and McLean's IS success model extended through applying an analytic hierarchy process is used. A field study with 156 online customers and 34 managers/designers of e-business companies was performed. The study identified different relative importance of each website quality factor and priority of alternative websites across e-business domains and between stakeholders. This study also found that the website with the highest quality produced the highest business performance. The findings of this study provide decision makers of e-business companies with useful insights to enhance their website quality.

Investigating the effect of website quality on e-business success: an analytic hierarchy process (AHP) approach

This study presents an empirical investigation of factors affecting small- and medium-sized business (SMB) executives’ decision to adopt anti-malware software for their organizations. A research model was developed by adopting and expanding the protection motivation theory from health psychology, which has successfully been used to investigate the effect of threat and coping appraisal on protective actions. A questionnaire-based field survey with 239 U.S. SMB executives was conducted, and the data were analyzed using partial least squares (PLS). This study demonstrates that threat and coping appraisal successfully predict SMB executives’ anti-malware software adoption intention, leading to SMB adoption. In addition, considerable variance in adoption intention and actual SMB adoption is addressed by social influence from key stakeholders and situation-specific variables, such as IT budget and vendor support. Further, the generalizability of the model was tested using industry type and IS expertise. The adoption intention of IS experts and IT intensive industries was mainly affected by threat appraisal and social influence, while that of non-IS experts and non-IT intensive industries was significantly influenced by coping appraisal and IT budget. Vendor support was a key facilitator of the anti-malware adoption for IS experts and IT intensive industry groups, while IT budget was for non-IS expert and non-IT intensive industry groups. Key implications for theory and practice are discussed.

Threat or coping appraisal: determinants of SMB executives’ decision to adopt anti-malware software

Developing a usable website is pivotal for e-business success. Researchers have devoted effort to develop metrics, guidelines and theories of website usability, yet there still is a lack of consensus on the multifaceted dimensions of website usability and lack of investigation of the nomological networks among website usability constructs. This study first investigated the common dimensions of website usability by integrating the findings of previous studies and a focus group study with website usability experts. Instruments to measure the constructs were developed and empirically validated. Then nomological networks between website usability constructs and between those constructs and online purchase intention and purchase were examined. Three field studies including two questionnaire surveys and a causal mapping analysis were conducted. The research identified ten website usability constructs with strong psychometric properties. A number of nomological networks between usability constructs were discovered, contributing to identification of sources of variances of purchase intention and purchase behavior. Findings of this study are expected to provide useful insights for practitioners to develop more usable websites and for researchers to better assess the effect of website usability on online customer behavior.

Understanding of website usability: Specifying and measuring constructs and their relationships

Past studies suggest that computer security countermeasures such as security policies, systems, and awareness programs would be effective in preventing computer abuse in organizations. They are based on the general deterrence theory, which posits that when an organization implements countermeasures that threaten abusers, its computer abuse problems would be deterred. However, computer abuse problems persist in many organizations despite these measures. This article proposes a new model of computer abuse that extends the traditional model with the social criminology theories. Focusing on computer abuse within organizations, the model explains the phenomenon through social lenses such as social bonds and social learning. The new model contributes to our theoretical body of knowledge on computer abuse by providing a new angle for approaching the problem. It suggests to practitioners that both technical and social solutions should be implemented to reduce the pervasive computer abuse problems.
