美国质量管理学家朱兰说过：产品质量就是产品的适用性，也即产品满足用户需要的程度，换句话说，产品质量不只是由它适用的绝对标准确定的。一个在高度工业化市场认为是高质量的产品，到了工业化程度不高的国家可能会认为是不合格的产品。由此可见，不计成本刻意追求高标准， According to Juran, a quality management scientist in the United States, product quality is the applicability of a product, that is, the degree to which the product satisfies the user’s needs. In other words, product quality is determined not only by the absolute standards to which it applies. A product that is considered to be of high quality in a highly industrialized market may be considered to be a substandard product in a country with a low level of industrialization. From this we can see that we are pursuing high standards irrespective of costs.
