New product and service development is concerned with the essential process in all companies and organisations of continuously developing new product and/or service offers. NPD starts from a new market/business opportunity identified in the company: it is the process of "transformation of a market opportunity into a product/service available for sale" (V. Krishnan, T. Ulrich). Considering the changes in technology and related social patterns of consumption and product use, NPD has gone through enormous changes, evolving from a purely physical product focus to an integrated holistic development of solutions including a physical product, electronics, software, services, internet and related apps. This has led to important changes both in the process and the composition and organisation of the NPD teams. The NPD process has evolved from a sequential process to a complex multi disciplinary and iterative process with rapid prototyping and direct user testing cycles. This course aims to take the students through this complex process, by a hands-on and practical experience developing a product/solution for a real company with a real brief. It will introduce the students to different tools and steps to come from a initial company brief to the testing of a final prototype. From the understanding of the brief and the challenge, to getting insights from the potential customers, converting insights into specific design objectives and functions to finally define and develop a prototype, a test plan and execute a test with end users. Point of departure is the need for prototyping and testing in order to keep up with the fast product development cycles and to teach the students to be able to develop in a short term and a flexible manner new products and/or experiences. ("Lean product development"). The course will have a pragmatic focus where theory has a supporting role for the main objective of developing a real solution for a real brief of a company. An important aspect of this process will be optimal teamwork.
