The primary reason behind the unsatisfactory results is the lack of a theoretical framework： what strategic variables to include in the analysis and their relative importance; the definition of an industry, and how to make competitive strategy operational. First, the author presents a customer-oriented theory of management which submits that, like Procter and Gamble, understanding customers should be the primary focus of a business. Second, the author proposes an integrated approach to competitive strategy. Because customer-perceived quality is far more critical to long-term success than any other factor, it should be the centerpiece of competitive strategy. The author suggests that competitive strategy should be divided in two interdependent dimensions： external and internal. It is the external strategy that should be considered the primary dimension because it reflects the customers＇ perspective, and provides a sense of direction regarding how the internal resources should be used. Next, the author presents an operational framework of competitive strategy which proposes that the best route to market share leadership in consumer markets is competing in the mid-price segment, offering superior quality compared to competition at a somewhat higher price： （1） to maintain an image of quality, and （2） to ensure that the strategy is profitable and sustainable. Finally, the author offers a framework of business or industry definition that extends Abell＇s （1980） three dimensions to seven. He suggests that an integrated approach to market segmentation provides the foundation for conducting strategic group analysis in consumer markets. So, in strategic group research, we need a bottom-up approach that begins with a product-market segment. In each product market, real competition occurs at the brand level. This is the ground where actual competitive wars are fought, and this is where the rich dynamics of competition often come to light.展开更多

This theory argues that people＇s motivation is a developmental process across time and place. Furthermore, it emphasizes that three basic psychological needs--a need for competence, a need for autonomy, and a need for relatedness--are the nutriments of motivation. Thus, as this theory not only concerns the type of motivation, but also the circumstances that promote and maintain motivation, it offers insight to the nature of lecturers＇ motivation. It is claimed to be one of the most influential theories in contemporary motivation psychology展开更多
