The success of information systems (IS) projects continues to be low despite many initiatives to address the issue. Given the importance of IS for organizations, it is a key imperative for software development firms to understand what is needed to deploy high-quality and successful systems. This is systems that are adopted and used, which by extension can contribute to goal satisfaction and business value. The notion of successful systems is even more important for developing regions, such as the English-speaking Caribbean (ESC), as such regions have far less capacity to absorb these failures (when compared to software development firms in developed countries). Understanding the factors that impact the quality outcomes of IS projects (i.e. antecedents of IS success), is considered key to the success of these projects. This study therefore aims to provide a research model that identifies key factors impacting IS project quality and success, while taking into account the unique characteristics of developing countries (in this case, the ESC region).
