CASE STUDY

Corporate Quality Culture Enhancement

To enhance corporate quality culture with continual improvements on product quality, production efficiency and cost reduction, TSMC fully promoted the "Suggestion" in basic level and the activities of "Continual Improvement Team (CIT)". TSMC also held a corporate-level "Total Quality Excellence and Innovation conference". In 2017, there were 42,056 suggestions issued at the grass roots level, and a total of 2,020 continual improvement team activities were registered and implemented. Among them, 45% of continual improvement team activities focused on product quality enhancement.
