整合限制理論邏輯樹圖工具於課題達成型QC Story之運用~個案研究

Abstract

企業界在品質管理領域，「QC Story (品管改善歷程)」被公認為有效解決問題模式，其優點在於簡單易學，透過明確的步驟與品管手法工具的配合，協助同仁來分析解決問題。然而，實務運用上，非生產現場作業人員，所負責處理的問題，則多為管理層面的問題，當其運用「課題達成型QC Story」來改善問題時，常發現品管手法工具較不易使用。限制理論(TOC)的思維程序(Thinking Process)配合邏輯樹圖使用，優點在於活用常識管理及系統思維，運用簡單的因果邏輯來分析問題。如能結合TOC系統思維將能使「課題達成型QC Story」改善更為有效，此乃本研究之目的。 本研究應用一個實際個案來進行解釋說明與驗證，以課題達成型QC Story之問題解決模式為基礎，配合運用限制理論思維程序的邏輯樹圖手法工具，提供不同於原有課題達成型QC Story手法工具運用的思考方式，協助業者於問題解決或改善時的參考。

In the quality control domain, “QC Story” is recognized as an effective model for problem solving. The strength of QC Story lies in simply easy to study, and by the coordinated application of explicit step with Quality Control tools. That assists the colleague to analyze and solve the problem in business. However, in the real practice, the problems that are responded by non-manufacturing persons, are most the management problem. So, when they solved the problem with “Task-Oriented QC Story”, they ofen found the QC tools not easy to be used. Meanwhile, the strength of Logic Tree Tools of TOC Thinking Process lies in its exploiting of common-sense management, system thinking and employing of cause and effect analysis. The goal of this study is try to integrate the Logic Tree Tools with the Task Oriented QC Story, to enable the “Task-Oriented QC Story” to be more effective. This study applies an actual case to carry on the explanation to show and to confirm the integration of Task Oriented QC Story and the Logic Tree Tools of TOC Thinking Process. That could provide different thinking model to be a reference for problem solving or continual improvement.
