Although systems development methodologies (SDM) are believed to help improve the software development process, the deployment of SDMs often encounters developers’ resistance. Agile methodologies, the latest batch of SDMs that are better in dealing with volatile business requirements, are likely to face the same problems since they require developers to drastically change their work habits and acquire new skills. Therefore, it is essential to identify the factors that could potentially influence individual developer’s acceptance of agile methodologies. This paper reviews the literature on the acceptance of SDMs and agile methodologies, which serves to assess current understanding in the acceptance of SDMs and agile methodologies. From this review, we identify a set of potential factors and develop a framework to guide future research in individual acceptance of agile methodologies.
