Quality strategies, policies and goals focusing on customers′ needs are clearly established. Continuous quality improvement has been adopted as the corporate strategy to improve its performance and competitive edge. This paper presents the successful implementation of a quality improvement project using the work study approach. On the completion of the project, the rate of serious defects which may lead to an accident is reduced by 55%, i.e., from 2%￣0.9% over a period of two years. A total of HK$ 1.1 million spent on the project is justified when compared with the reduction of financial risks involved. The success of the project demonstrates that the work study approach could be an effective tool for improving the performance of maintenance work.展开更多

When adapting a workflow process definition to specific needs or changing the structure of the workflow process as a result of evolutionary change, coarse-grained reuse of work- flow is of significance to the reduction of the work effort, modeling system and enhancing the reliability of their work. Based on decomposition of workflow tasks and teamwork, this paper proposes an approach to describing interoperability behavior between roles in teamwork by using activity-pattern. In activity-pattern, abstract mechanisms of activity specialization and activity aggregation are presented, enabling reuse of workflow by means of reuse of interoperability behavior between roles. The experimental system shows that our approach presented is feasible.展开更多
