This paper has focused on the importance of human resource information system (HRIS) implementation in the organization to achieve the competitive advantage. This study proposed a research framework which is derived from diffusion of innovation (DOI) theory and technological, organizational, and environmental (TOE) framework. For the purpose of this study various determinants that could influence the adoption of HRIS such as IT infrastructure, IT expertise, financial readiness, HR practices and competitive pressure have been evaluated. A proposed methodology is established in the paper which could assist futuristic researchers who are willing to pursue their study in similar context. Previous studies had focused the process of HRIS adoption at decision stage (stage 3 of adoption process in DOI) as dichotomous scale though none of the studies have developed the scale for HRIS implementation (stage 4 of adoption process in DOI). Along with identification of literature gap, this study has also exhibited theoretical and practical implications with regard to HRIS adoption.
