摘要: 尽管众多的学术论文已经证明限制理论的生产及配销解决方案,在企业改善中得到
显着的改善绩效,但是对于实务操作的经理人来说,仍不免有以下质疑:一、限制理论
的改善方案仅仅只是一种思维及概念性的逻辑,缺乏具体之执行细节及步骤;二、众多
的改善结果显示,企业必须具备一定的管理基础及架构,经历一段不算短的时间之后才
能获得显着的改善绩效,如果缺乏这些管理技术及基础架构,应用相同的解决方案是否
依旧可以得到文献所呈现之效果,快速的获得显着改善绩效呢?针对第一点的质疑,
Goldratt 博士提出了限制理论的战略及战术树图,提供了具体执行步骤及说明,作为改
善方案的指导方针及蓝图,但是至今仍缺乏实际案例的深入验证、探讨其可行性及有效
性;针对第二点,除非透过真实的成功案例加以验证,否则对于管理基础架构不是很完
善的企业,依旧会对此改善方案的导入心存犹豫及怀疑。
本文将以两个不同生产型态、管理基础差异极大、位处海峡两岸的企业,记录实际
的改善导入过程、结果、建议及心得,作为验证限制理论生产改善方案的可行性及有效
性。其中大陆的家具企业在缺乏良好管理基础之情况下,与具备专业管理基础的台湾航
太零件制造企业,分别在不同时间采用相同的限制理论改善工具,采用其生产改善之简
化型驱导式生产系统,在Goldratt 所提出的战略及战术树指导架构下逐步的实施改善
行动。
本文透过实际案例导入限制理论改善之过程,希望达成以下之目标:一、验证
Goldratt 博士所提出解决方案之细部执行细节-战略战术树之可行性及有效性;二、具
备良好的企业管理基础、架构并不是导入限制理论改善工具的第一必要条件,希望在短
期内获得显着的改善绩效,应该优先建立可以稳定系统的机制,而不是使用各种改善手
法到处进行改善;三、在生产型态、管理基础、经营环境各种条件迥异之情况下,应用
相同之改善工具所产生之差异、需要客制及修正的内容,记录其过程及心得,可提供实
务改善工作者参考。
Despite hundreds of reported accounts of successful Theory of Constraints (TOC)
Simplify Drum Buffer Rope (SDBR) implementations, shop floor managers still raise
two immediate concerns: (1) TOC SDBR solutions are conceptual only and lack solid
implementation steps to effect the change. (2) A good management foundation is a
pre-requisite for SDBR implementation; building such a management foundation
should be the priority. For the first concern, Goldratt developed Strategy and Tactics
(S&T) trees to provide step-by-step guidance for effecting the change. However, other
researchers have not extensively researched Goldratt’s approach and its
effectiveness has not been empirically validated. Regarding the second concern,
unless a successful case can disprove it, the concern will remain. Consequently,
companies with a poor management foundation will hesitate to adopt SDBR and miss
significant improvement potentials. This paper presents a case study of a Chinese
furniture manufacturer that, like most other Chinese manufacturers, lacked a good
management foundation. Nevertheless, the company adopted Goldratt’s SDBR S&T
tree and the related logic and implementation steps were followed accordingly. The
objectives of this case study are to validate that: (1) the logic of the SDBR S&T tree is
robust and effective and (2) a good management foundation is not a pre-requisite for
implementing TOC SDBR. The key to achieving successful improvements is to adopt
the right concepts, establishing mechanisms to stabilize the system first before kaizen
(changing the processes to reduce variability and set-up time etc., which is the focus
of Lean and 6 Sigma).
