This document discusses Total Quality Management (TQM), including its key elements, benefits, and applications through two case studies, as well as some failures of TQM implementation. The two case studies describe how ABC Bank improved customer satisfaction through cultural change workshops, and how a photography equipment company achieved quality improvement through consultant-led training and cross-functional project teams. Some failures discussed include a nuclear power plant accident due to lack of training, a dam collapse due to improper materials and maintenance, and network issues with the iPhone 4 that Apple initially did not acknowledge.
