Design and validation of a comprehensive model for risk-assessment in product development

  • Abstract Shorter development time of new products and a shift from complicatedness to com-plexity (see Glossary: complex vs. complicated) requires new thinking in product de-velopment. To handle this trend there is a need for a better and more comprehensive knowledge of risks and challenges in product development. There are a number of risk evalua-tion methods available focused on different goals; e.g. project management, prod-ucts, organization. The scope of this thesis is not to add another new method to the market but to create a practical approach handling risks and challenges in product development in a more comprehensive and integrated manner. All activities in this method, from the technology roadmap to the start of production, are based on common and approved methods; e.g. Failure Mode and Effect Analysis (FMEA), Value Analysis, Kano model. The objectives are reducing lead-time in product development and to make schedul-ing more manageable. To reduce the lead-time a new and modified approach of the FMEA method is used. To increase the efficiency of the method, without any appre-ciable decrease of the effectiveness, risks, evaluated by severity and occurrence will omitted from further consideration below a certain threshold level. A further increase of effectiveness and efficiency is expected from the strategy that the technique is based on common and approved methods, to initiate the method with a “flying start” and also to reduce the employee’s resistance against new meth-ods. This thesis was carried out in cooperation with Dräger Safety, Lübeck, to set up a method for practical use which can be validated in practice. This thesis is structured into 4 sections: 1. Basic principles of risk management 2. Description of structure and behavior of risk management handling in product development 3. Exemplary validation of the new risk evaluation in the context of the product development environment at Dräger Safety (in extract) 4. Discussion and outlook
