This document discusses quality management techniques including total quality management (TQM), lean thinking, kaizen, and the different types of wastes they address. TQM is defined as an organizational approach to meeting customer expectations through continuous improvement. Lean thinking focuses on eliminating waste. Kaizen emphasizes continuous small improvements through team-based approaches. The three main wastes addressed are muda (non-value adding activities), mura (unevenness of workflow), and muri (overburdening people or equipment). The document concludes that while each technique has advantages, combining approaches can yield the best results for quality improvement. Firms must also maintain quality levels over time through ongoing inspections.
