Abstract

As part of its commitment to empowering people to make informed consumer decisions, the Consumers' Association investigates the convenience aspects of a vast range of products, from cars to garden spades. Evaluation approaches include user trials, convenience checklists and expert appraisals. Our methodology is subject to constant review and refinement to ensure the highest levels of reliability, validity and auditability. We have a distinctive approach: our tests are designed to reflect consumer usage and to provide comparative data which is absolutely fair to all products. This paper discusses the evolving nature of that methodology within the "lifetime" of a product. Reasons for choosing each method are given as practical guidance for those involved in comparative testing.
