【摘要】 本文研究了企业在导入精益或构建自己的生产体系时所遇到的文化困境及缺乏驱动的问题,分析了以丰田为代表的优秀精益企业所具备的文化特点及其文化培育的方式,构建了针对企业内管理层、团队层次及个人层次的精益改善驱动机制。企业在导入精益时通常关注与精益技术体系的学习及建立,通过外聘精益专家作为指导,内部建立精益推进团队,希望在短时间内建立起类似丰田的JIT模式。本文针对这种没有深入理解精益的现象,提出了精益文化的体系,细致的分析的精益企业中员工在物质层面、观念层面及基本假定层面所应该具备的文化特点,为企业指出了导入精益的关键所在。本文分析了精益改善在企业进步中的作用,并阐述改善与创新这两种管理思想对企业的影响,以及结果导向和过程导向在改善过程中的影响,认为精益企业必须认识到改善,即发现并解决问题,是企业进步的重要源泉,并且管理者在主导改善活动时要能够平衡好结果与过程的关系。企业在精益的实施中,如果未能考虑各种驱动因素并协调好这些因素,改善的力量会逐渐被内部的矛盾所侵蚀。因此,本文分析了管理层导向改善的过程驱动及结果驱动机制,通过ANP方法定性的分析了过程驱动的5种力量,通过三个层次递进的提供了结果驱动机制的方法;分析了团队导向改善的驱动机制;分析了基于个人导向改善的建议系统及员工激励问题。
【Abstract】 Manufacturing enterprises may face the culture problem or lacking the driven mechanism when introducing lean manufacturing system. This paper made research on how to solve those problems. The paper analyzed the culture system of a excellent lean enterprise such as Toyota company, and constructed driven mechanism for management level, team level and employee level.Enterprises tend to focus on learning lean technical system by the guidance of lean expert from consulting firms. They set up internal teams to push lean project in the hope of constructing JIT way in a short time. According to this situation, this paper proposed lean culture system. The system analyzed the proper way employees should accept, which included physical level, concept level and basic assumption level.This paper analyzed the contribution of lean kaizen to the improvement of enterprise. It described the impact of kaizen and creation, which are two different improving methods for enterprises. Lean enterprises should realize that kaizen is the source of improvement. The essence of kaizen is observing and solving problems. The paper pointed that management should balance the result and process during each kaizen activity.During the lean project implementation, if enterprise did not consider all related driven factors or could not coordinate them well, kaizen activity may be weaken by internal conflicts. So, this paper analyzed driven mechanism for lean project in three levels. It proposed management driven mechanism in the view of process, and analyzed 5 strengths with ANP method quantitatively. It proposed management driven mechanism in the view of result by three steps. It also proposed driven mechanism of task level and employee level. Those driven mechanism can help manufacturing enterprises consolidate the implementation of lean project.
