After the ISO9000 series of quality management standards was released by the International Organization of Standard, certificate of ISO9001¡G1994 was deemed by enterprises as a guarantee for performance improvement. Ironically, not until recently is the implementation of ISO9001: 2000 substantially depreciated and suspected as an obstacle to efficient operation. Since the certificate of ISO9001 still represents the passport to be a candidate in international trade, enterprises bear to implement ISO9001 even under the circumstance that they do not understand the value of ISO9001. This not only violates the basic requirements of ISO9001: 2000 but also leads to employee¡¦s careless attitude about the practice. The prevalence of different evaluation tools such as Key Performance Index (KPI), Management By Objectives (MBO) and etc. tells the story that enterprise nowadays puts performance before anything. However, most enterprises fail to integrate the similar concepts behind evaluation indexes and ISO like quality goal, quality review, human resource, and process management and treat each index as an independent system. This has caused enterprises serious waste and cost. Also, there is always lacked an objective evaluation method between human resource development and performance management. Enterprise performance management system is often criticized for its isolation from the real competitive environment and helplessness in staff encouragement or efficiency improvement. The fact that the current quality system and performance management system cannot reflect customer¡¦s voice, the main source of profit improvement, undermines the benefits of system implementation and is against the expectation of persistent development. Through in-depth interview, this study specifies how enterprises in LCD industry implement performance evaluation and ISO9001: 2000 and clarify the correlation between these internal systems and the disconnection occurred. Based on bibliography and theory study, then conduct to an integrated operation system that has two major parts, including mixed-construction and process management. The process oriented management flow could easy to connect the performance evaluation gap between enterprise and customer concern. The mixed-construction could meet the performance evaluation request of LCD industry which is customers¡¦ satisfaction¡Bspeed and competence. Through this kind of operation system, enterprise could easy to put customer concern in the enterprise internal system and also could achieve a closed loop of continuous improvement. That is also called as system synergy. In enterprises operation, cost reduction stands as important as profit seeking. The concept of integration of performance management system and ISO9001¡G2000 quality management system indicated in this research provides a way to meet the targets of performance and cost while promoting employee satisfaction, enterprise competitiveness and customer satisfaction.
