Market and technology changes have brought about new characteristics of product development. One of the most significant changes from the traditional to the new paradigm is the change from sequential and collocated development processes to concurrent and distributed processes. Although some researchers have built models of development processes and product development performance, most of these studies are about collocated development projects where the coordination between tasks is not explicitly studied. Consequently, there is a need to model the relationships between development processes and project cycle time in the distributed context, with special attention to the coordination between tasks. With the support of a design company, we developed and validated the model with data from mobile phone projects.
