Profit by Design is a very hands-on innovation project that is organized by the Delft Design association in cooperation with the local authorities. During the last months Barbara Vos shared her expertise with three attending companies that she gave her help to enrich their product and marketing strategy with the power of product design. These companies varied from the food industry sector all the way up to a metallurgy testing and service provider. Though a broad spectrum of industries they all had in common that they improved their competitiveness by the integration of product design as strategic part of their product development and marketing processes. The results of the fruitful cooperation’s within this innovation project were gathered in a booklet (in Dutch) that was presented on March 21st to Ferrie Förster councilor of the city of Delft.
