Retraining the process of new product development: From “stages” models to a “blocks” framework

The traditional view of the process of new product development (NPD), which is often prescribed as a series of activity “stages”, is critically reviewed. A number of problems are identified with this and other approaches to NPD as accurate representations of the process, such as their concentration on intra‐firm aspects and their ordered and sequential structure. The paper argues for an alternative approach, based on variable “blocks” of NPD activities, which also takes account of external organizations' involvement in the process.
