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

Extended model reduces the redundancy of roles, lowers the complexity of authorization management and enhances the flexibility and maintainability of users＇ authorization. It is well proved in its application in postgraduate student management system.展开更多

This paper intends to cast light on the management of project-oriented workflow. A comprehensive authorization model is proposed from the perspective of project management. In this model, the concept of activity decomposition and team is introduced, which improves the security of conventional role-based access control. Furthermore, policy is provided to define the static and dynamic constraints such as Separation of Duty (SoD). Validity of constraints is proposed to provide a fine-grained assignment, which improves the performance of policy management. The model is applicable not only to project-oriented workflow applications but also to other teamwork environments such as virtual enterprise.展开更多
