Mere capitalization on the cheap availability of labour and land in the China's Mainland for competitiveness is no longer viable because of the emergence of new competitors in particular those in Asia countries. TQM aiming for continuous improvements is the key for profitability growth and long run competitiveness. Over emphasis in the “hardware” for quality improvement without the complementation of it with the cultivation of the “software” for its implementation will not only delay the real implementation of real TQM but may also result in catastrophic failure of the organization in the face of rapid changes in demand and expectations of customers. An organizational culture for quality improvement through management empowerment is believed to be fruitful in helping the Hong Kong manufacturers to win the uphill battle for their well being and even survival in the world competition.展开更多
