Printed by Chalmers Reproservice Gothenburg, Sweden 2014 Abstract Product development companies strive to provide their customers with high quality products, more quickly than their competitors, using as few resources as possible. One way of managing all three aspects at the same time is to reuse old, quality assured designs and knowledge in new products. A common way to do that is to create a platform with designs that are reusable in many different products.

Traditionally, research on platforms has focused on finding ways to provide manufacturing with a low number of parts to be able to increase utilization of expensive production equipment. However, reuse of parts does not benefit all businesses, especially those where customer requirements continuously change. To cut development lead-time, other types of reuse are necessary. The use of platforms based on core technologies and re-configurable systems as platform elements may provide the necessary support. They enable reuse on a more

Abstract

level, reusing technologies, requirements and concepts rather than ready designed parts. This thesis elaborates on support for working with the type of platforms that are integrated across the lifecycle of a product.

The studies in this thesis show that platform approaches in literature today do not cover the need to support holistic platform development across all stages of a lifecycle.

As a solution, configurable system elements are used to model platforms and the links between the lifecycles. The development processes and models may be further infused with set-based concurrent engineering to provide a framework for efficient development.

These principles are integrated into the models and the processes to enhance the ability to manage the complex relationships within and between parts of the platform throughout the lifecycle.

Further, development platforms may be supported by a Product Lifecycle Management (PLM)architecture for engineering-to-order configuration, but it can also serve as a tool to learn about the knowledge gaps that need to be filled to get a product that meets requirements.

Keywords: product development, platform-based development, set-based concurrent engineering, product lifecycle management, configurable components.

i ii Acknowledgements This thesis was carried out at the department of Product and Production Development, Chalmers University of Technology in Gothenburg, Sweden. I would like to express my sincere thanks to my supervisor Professor Hans Johannesson who gave me the opportunity to pursue my own ideas, providing me with guidance when I needed it. Also, thank you Professor Johan Malmqvist, my co-supervisor, for your eye-opening comments and for posing the difficult questions.

I would like to thank my co-authors Marcel Michaelis, Dag Raudberget, Anders Forslund, Dag Bergsjö and Daniel Corin Stig for the moments of inspiration and creativity and for sharing the moments of pure pain. To Roger Jiao at Georgia Institute of Technology and Kevin Otto at Singapore University of Technology and Design, thank you for accommodating me and letting me propel my research through your guidance.

Funding for these visits, and my research in general comes from the Wingquist Laboratory VINN Excellence Centre under the umbrella of the Production Area of Advance at Chalmers. The Centre is supported by VINNOVA, the Swedish Governmental Agency for Innovation Systems. This support is greatly appreciated.

I would further like to direct my thanks to the people from our industrial partners, which I have had the pleasure to make acquaintances with during our studies. Thank you everybody at GKN Aerospace, Volvo Cars and Emerson Rosemount Tank Radar who has participated in our studies and assisted in making them happen, especially Ola Isaksson who helped to provide intriguing spot on cases for testing my work.

The time at PPU would not have been the same without my lovely colleagues. The quirky, intelligent, and inspiring discussions during coffee breaks have made it easier to get up in the morning. I am especially grateful to Anders Forslund, Marcel Michaelis and Ola Wagersten whom I have depended on heavily during the last few years. This would not have been possible without you.





I would like to thank my parents, siblings, my old friends and my new friends for supporting me through happiness, agony, success and failure. A special thanks goes out to my grand parents who always believed in me. Finally, my most sincere thanks go to Helena for keeping me straight when I had the world on my shoulders.

xii Introduction “The world as we have created it is a process of our thinking. It cannot be changed without changing our thinking.”

- Albert Einstein Product development is all around us. The products that we use every day, such as the computers we are using in our work, the car that almost ran you over on your way to work, or the toaster that makes our bread crisp and delightful for breakfast are all results of product development. Often, companies have several thousand employees working with developing new products for the market; a market that is more or less unpredictable. The economic success of most companies depends on how well they are able to identify and interpret the needs of their customers and quickly create products that answer those needs and that can be manufactured at low cost (Ulrich and Eppinger, 2008).
