Briefly summarize how fads in the corporate culture have changed in the past twe

Twenty years ago, business practices were called "quality circles," in which workers and a manager met regularly to try and improve the quality of both working conditions and the company’s products. Thousands of companies across the U.S. practiced quality circles, but have since changed to a "team concept" for problem solving. Today, other fads in the workplace are common. For example, "cook-offs" are the latest fad, in which corporate teams slice, chop, and sauté against the clock while professional chefs oversee and judge the event. Team-building exercises will soon pass and be replaced by yet another fad.
