The purpose of this paper is to study approaches and means relating to the social loss concept propounded in quality engineering, in order to introduce this concept into a corporation and make it well known. Process improvement (feedback control) by online quality engineering had proven inadequate, so this case study returned to parameter design, attempted to optimize toothpaste tube bonding conditions, and then applied online quality engineering. When 3 million tubes are produced annually, the improvement effect is about 100 million yen. Performing a loss calculation for each step, taking this step before volume production begins, and implementing remedies to tube bonding failures that have actually occurred in the field were made explicit to the company. As a result, an educational effect was observed from the bottom level of production personnel through the middle management level. The findings suggest that management has an important role to play in not stopping at simple problem solving and in avoiding the pitfall of partial optimization in technology development.
