ABSTRACT
Product development is the process of transforming a 'product definition' into a final product under given constraints like cost, time etc. A general trend is a more methodical development process due to increased product complexity, competitiveness and demands on quality. Testing consequently has to become a more integrated part of the process than it is today. A fundamental physical approach on design is an advantage in many respects for most steps within the development process. Relations between systems, sub-assemblies, components and critical points may easily be generated by ordinary dynamic modelling and flow analyses. Failure mechanisms with their models are thus directly related to overall functions. The need for testing and its degree of acceleration may vary depending on the type of product, company, etc., but also on the type of problem and in what stage of the development process it is done. Continuous component and material tests and access to equipment and people who know how to do different types of tests is an important and necessary preparation for modern development.
