An Information Model for Product Development: A Case Study at PHILIPS Shavers

This paper presents an investigation into the development of an information model to support the Product Development Process (PDP) of shaving devices at PHILIPS. Firstly, challenges of the PDP were identified by carrying out interviews with several systems engineers and product architects. It was found that an increase in product functions combined with a shorter time to market has resulted in higher information densities and larger information flows during the PDP. As a result, managing uncertainty, communication and documentation has become increasingly difficult. Secondly, the information flow in the organization was formalized at the hand of interviews with the development staff in all involved departments and by investigating the available documentation of former projects. Thirdly, the information flow was translated into an information model to support the future development of new shaving devices. The resulting model consists of two paper based design support tools, namely, the MetroChart and the Design Parameter Matrices. The former is a paper-based design support tool that provides a compact overview of the processes that different development teams have to undergo during the PDP of a new shaver. The latter provides a detailed description of the relations between design parameters, process steps, and components. Current efforts are made to determine how to implement the model from an organizational point of view, as the number of developers, disciplines and departments involved in the design of this product is rather large and small errors can lead to large losses.
