Contributor Den Hollander, M.C. (mentor) Bocken, N.M.P. (mentor) Faculty Industrial Design Engineering Department Design Engineering Programme Master of Science Strategic Product Design Date 2016-03-29 Abstract The book 'Products That Last: Product Design for Circular Business Models' was published as the result of a research project from the faculty of Industrial Design Engineering of Delft University of Technology to shed more light upon how to build businesses that are able to profit from longer product lifetimes and on how to design products that are specifically suited for use in these business models. There is a further need to validate the framework that is presented in this book, to test its applicability, and to expand it by looking into possible relationships with product classes and types. This graduation thesis aims to contribute to knowledge on circular product design by doing this. The external validity of the classifications that the framework describes was investigated by mapping a large variety of products on the framework. The business models and product designs of companies that are able to profit from an above average product lifetime were studied. The levels of applicability of product design strategies for the business model archetypes of the framework were studied by comparing measured levels of application to the indications in the framework. Using the acquired data, possible relationships with product classes and types were analysed statistically. Two design cases were organised in cooperation with Philips to assess the applicability of the framework in the development of a new business model for an existing product with a long lifetime and the development of a new product for an existing business model archetype.
