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.
作为致力于帮助人们做出明智消费决策的一部分，消费者协会对从汽车到园艺锹等众多产品的便利性进行调查。评估方法包括用户试用、便利性清单和专家评估。我们的方法会不断接受审查和完善，以确保最高水平的可靠性、有效性和可审计性。我们有一种独特的方法：我们的测试旨在反映消费者的使用情况，并提供对所有产品绝对公平的比较数据。本文讨论了该方法在产品“生命周期”内不断演变的性质。给出了选择每种方法的理由，为参与比较测试的人员提供实际指导。
