Drivers of liking (DOL) studies are useful for product development to formulate acceptable products; however, DOL alone are insufficient for understanding why a product is purchased and repurchased, which is ultimately the indication of a successful product. Ultimately sensory attributes drive product success (that is, repeat and continued purchase). However, ignoring the importance of extrinsic factors may neglect the vital product attributes responsible for the initial purchase, which may in turn, affect repeat purchase. The perception of sensory attributes assessed by DOL is mitigated by external perceptions of quality. If the sensory attributes do not deliver based upon the quality cues, the product will not be acceptable. Four key extrinsic factors that affect DOL are the perceived satiety, brand and labeling, price, and the emotional impact to decision making. In order to more thoroughly understand what the DOL for a product is, these 4 product cues should be considered in conjunction with sensory attribute perception to gain a holistic understanding of product acceptance.
喜好驱动因素（DOL）研究对于产品开发以制定可接受的产品很有用；然而，仅靠喜好驱动因素不足以理解为什么一种产品会被购买和再次购买，而这最终是产品成功的标志。最终，感官属性推动产品成功（即重复购买和持续购买）。然而，忽视外在因素的重要性可能会忽略导致初次购买的关键产品属性，这反过来可能会影响重复购买。通过对质量的外部感知，由喜好驱动因素评估的感官属性的感知会受到影响。如果感官属性不能基于质量线索来呈现，产品将不会被接受。影响喜好驱动因素的四个关键外在因素是感知饱腹感、品牌和标签、价格以及对决策的情感影响。为了更全面地理解一种产品的喜好驱动因素是什么，应该将这4个产品线索与感官属性感知结合起来考虑，以全面了解产品的可接受性。
