Kaizen has its origins in post-World War II Japanese quality circles. These circles or groups of workers focused on preventing defects at Toyota. They were developed partly in response to American management and productivity consultants who visited the country, especially W. Edwards Deming, who argued that quality control should be put more directly in the hands of line workers. Kaizen was brought to the West and popularized by Masaaki Imai via his book Kaizen: The Key to Japan's Competitive Success in 1986.
2. The Goode and Cooke Company produces several models of frying pans. There is little difference in the production time required for the various models; the plant is designed to produce 160 frying pans per eight-hour shift, and there are two shifts per working day. However, the plant does not operate for the full eight hours: the employees take two 12-minute breaks in each shift, one in the first four hours and one in the second four hours; two hours per week are devoted to cleaning the factory and performing maintenance on the machines; one four-hour period every four weeks is devoted to the meeting of the quality circle. The plant usually produces about 3,500 frying pans per four-week period. You may ignore holidays in solving this problem. Answer the following questions by adjusting the data to a four-week time period.
Suggestion programs have always been popular in U.S. workplaces. Until recently, in most programs employees would write down their ideas and pass them on to management via a suggestion box. The widespread adoption of quality circles (QCs) and other group suggestion programs has changed this in many companies. Although QC programs are relatively new in the United States, we have studied their effects in a range of situations. The results of these studies are consistent and suggest that some purposes management has been putting the circles to are doomed from the start. But before we discuss the limitations of QCs and how management should use them, we want briefly to describe their characteristics and examine their popularity.
