What is Software Prototyping

The search for appropriate New Product Development (NPD) models or different approaches has become a new emerging topic both for scholars and practitioners. One of the latest results of these researches on NPD management is agile, to manage the increasing complexity of the NPD process. Physical product development, however, is much different from software development. Agile software development has been utilized to answer the challenges of software system development in spite of the lack of empirical evidence from academic research. The purpose of this chapter is to provide a systematic approach regarding the implementation of the Stage-Gate model and agile software in NPD process. Authors derived recommendations for practitioners who want to study Stage-Gate and agile methods in NPD and a research agenda for academics that highlights the need for further research in this area. In addition, the resulting systematic overview is useful as a reference work for researchers in the field of NPD and helps them identify both related work and new research opportunities in this field.
