This research study focuses on commercial firms that adopt a computerized Stage-Gate® decision support tool in their new product development process. The Stage-Gate® Product Innovation process is a well adopted and researched decision process in new product development. It is a structured and formalized process in which a variety of financial and nonfinancial information are captured and communicated to management to assist them in making decisions about the potential of new products. Given that the majority of a products cost are being determined at the product development phase, a series of decisions considering financial and non-financial information are usually made during the new product development process. Through case study research, this research investigates on how firms use decision support systems to assist them in their new product development decision process and evaluate the resulting impacts of the use of these systems in practice in the new product development context.
