The paper compares innovation management and information system (IS) literature, and argues that the climes about determinants of process innovation identified in innovation management literature are applicable to the software industry. Following on a comprehensive literature review and two semi- structured interviews with subject matters experts from two distinct software industries, a framework is proposed which maps the drivers and enablers of software development process evolution. INTRODUCTION The paper provides an investigation of historical and current drivers/enablers that impact on future Process Innovation within the Software Industry. The study is based on a combination of literature review and two case studies. The literature review include investigating the evolution of process innovation in innovation management literature as well as studying the origins of software process models and how these evolves from the IS literature. The study also examined two cases to better understand the influencing factors for adoption of new process model in industries and from commercial perspective. Process innovation in innovation management literature Voss (1994) indicates that product innovation often requires and occurs alongside process innovation. Stadler (2011) states, “scholars have long been interested in how processes need to be organized to achieve best outcomes in product development”. Despite this initial viewpoint, then traditionally the literature on innovation management has biased towards product innovation rather than process innovation (e.g. Brown and Eisenhardt, 1995; Verona, 1999; Krishnan and Ulrich, 2001). However, in parallel with the ongoing trend of managerial activity and institutional
