Think carefully about these 50 questions to help you build a solid foundation and review while learning new things. 1. What is the difference between true quality characteristics and surrogate quality characteristics? Quality characteristics that directly reflect customers’ expectations and requirements for a product are known as true quality characteristics ； Quality characteristics that companies establish as product standards and determine as product parameters in order to meet customers’ expectations and requirements, thereby indirectly reflecting the true quality attributes, are known as surrogate quality characteristics.
