In the last 50 years, a new principle regarding competitive advantage has emerged, and it is having a profound impact on the way we think of products and production. In the center of this line of thought are the quality of the product, the quality of the production process, and the relationship between the two. According to the “0th law of quality management,” the producer of highest quality is also likely to be the producer of the least cost product [1]. This principle runs in contrast to the formerly generally accepted concepts in economy.
