||Manufacturing Exective Systems (MES) has been developed for many years. Enterprises think that can improve the efficiency of production operations by implementation MES and then seek outsourced resources for implementation. Previously, case studies pointed out that each enterprise culture is different and faces varied problems in system implementation among them, people problem is the biggest especially. Theory of constraint creator Goldratt mentioned the goal of factory is to make money, the effective output can make companies continue to profitability, whether the effective output depends on the bottleneck, if the existing operating processes before the implementation of new system has not changed, it will not improve the performance of factory operations, and make it less competitive. After introducing the system into the factory, the senior manager can not feel the benefits after the introduction. The reason is that there is a new bottleneck. Therefore, this study explores the process by which a case company implement into the manufacturing execution system by using the theory of constraint tool to find out the system restrictions, to find out the main reasons for the situation, but these problems are not unsolvable, but because of conflicts and obstacles, still need to consider the hidden risks. In this study, past case information is provided to improve the case. The method of implementation is not perfect, but suitable. The research reference to the relevant literature, the inductive case company research results are as follows, to provide a reference for the future enterprise implement system:|
(A) Human error can only be reduced, but can not be avoided, mode of operation should be changed.
(B) Outsourcing choose industry-experienced software vendors, after the ability to consider its own development.
(C) Before the introduction of enterprises to establish internal MES system awareness, manufacturers should learn the relevant industry knowledge.
(D) To formulate short-term and long-term measures to reduce the dependence on the old system.
