High contrast consumer test: a case study

摘要

This paper addresses the application of high contrast consumer tests for product reliability improvement. The purpose of these tests is to define already during product development levels- and effects- of extreme use to a product and in doing so determining product weaknesses already early during product development. It has been designed, especially for innovative products, to prevent possible gaps between (often implicit) customer requirements and the actual specification. This is done by provoking interactions between early prototype products and a limited number of well defined (extreme) users during the early phases of product development.
