Functional Analysis and Risk Management in New Product Development Vince Thomson and Arman Oduncuoglu McGill University Department of Mechanical Engineering Presentation Outline • • • • • • • Motivation Objectives Cost and Risk Analysis Method (CRAM) Thermo-flask example Benefits of the method Conclusion Future work 2 Motivation • To assess the impact of engineering change as early as possible during the product life cycle. • In new product development (NPD) projects, it is important – to gain product knowledge as early as possible – to meet quality and customer requirements – to avoid cost and span time overruns. • To develop a tool to help managers and designers with their decision-making during the design process. 3 Objectives • To develop a tool which can assist project managers: – to quantitatively express product cost, development cost, development time and development risk, – to allow comparison among design alternatives, – to allow the tracking of cost and risk as change occurs in product design, • through – increased product knowledge during the early stages of design – a quantitative, data approach. 4 Overview of the Framework functions design characteristics 5 Details of the Framework: FAST Diagram -
