A specification model for product development

The specification processes in new product development is critical for obtaining a high quality, low cost and well interfaced product. However, despite the rich literature on product development, specification management has been given less attention. By means of two in-depth cases studies in one auto and one aircraft OEM (Original Equipment Manufacturer) located in Europe, the research reported here identifies the specification processes in the case companies. Comparative studies are conducted between the specification processes in the two companies. A model of specification management that identifies important steps from the conceiving of the idea to delivery and customer feedback is developed. It is concluded that following the steps proposed in the model could lead to a high quality product. The model proposed is not a best practise model but rather can help companies identify the critical steps from idea generation to design.
