Abstract

Adoption, use, and diffusion of Information Technology (IT) applications, together with their widespread success, are among the most popular topics in Information Systems (IS) research. However, the impact of the acquired understanding of those phenomena on IS practice is not discernible. In fact, IT adoption, use, and diffusion are subjects scarcely mentioned in what concerns the practices of IT/IS professionals. This article addresses the question of IT/IS practitioners’ awareness of models and theories regarding the adoption, use, and diffusion of IT applications and their success. It describes two surveys of IT/IS project managers that look into their knowledge on a selected set of models/theories widely addressed in IS research. The results show that these project managers are not aware of IT adoption, use, and diffusion models/theories. The article ends with a discussion that attempts to find justifications for that evidence and stresses out the need for further research focused on translating the extant theoretical models into actionable knowledge.

Highlights

  • Information Technology (IT)/Information Systems (IS) projects are difficult to manage [1] due to the complexity involved [2], and many of them result in failure [3,4]

  • The independent variables include a wide range of factors that have been recognized to influence the use behavior [13].Those theories were established upon theories from the social psychology realm that aim at explaining human behavior in general terms, such as the Theory of Reasoned Action (TRA) [14] or the Theory of Planned Behavior (TPB) [15]

  • The results of our study suggest that IT/IS professionals/project managers are not aware of an important set of models/theories that are at the core of the IS field, including the IS Success model [20,21,22], the Technology Acceptance Model [9,10], the Unified Theory of Acceptance and Use of Technology [11,12], and the Diffusion of Innovation Theory [16,17,18,19]

Summary

Introduction

Information Technology (IT)/Information Systems (IS) projects are difficult to manage [1] due to the complexity involved [2], and many of them result in failure [3,4]. The issue at stake is the adoption and use of IT applications, which for the past three decades has attracted considerable interest from the IS research community, resulting in the production and validation of several theories that have contributed to explaining the adoption and use of IT applications. Examples of such theories include the Technology Acceptance Model (TAM) [9,10] and the Unified Theory of Acceptance and Use of Technology (UTAUT) [11,12].
