Thirty years ago, customers’ primary demands were related to product quality. Once international competition met and ultimately surpassed the existing quality standards, it became critical to build quality assurance into most elements of the manufacturing process in order to remain competitive. With that accomplished, while still necessary as the price of entry, quality could no longer be considered a significant competitive advantage. Twenty years ago, with higher quality standards in place, service became a competitive advantage and the driving force in winning market share. Consequently, demands for service forced suppliers to look at customer satisfaction as the primary criterion for success.
