摘要

有效解決問題最重要的關鍵在於找出問題的根本原因。在強調以常識管理為出發點的「限制理論」問題解決模式是利用常識邏輯來探索問題的原因。它固然具有簡單易懂的因果關係的優點，但也具有一項重大缺點，就是現況樹缺乏量化衡量的觀念，所以很難讓問題管理者客觀的認定所選出的關鍵問題是否為真正的核心關鍵問題，此為一個不得不加以重視的課題。本研究因此選定關鍵問題的選擇作為重心，旨在尋求一個客觀的選擇機制。

為此，本研究針對限制理論選擇關鍵問題的既有方法與機制加以整理，做成一個清楚且易懂的流程架構；基於層級分析法具有量化衡量的機制，故本研究選定它來搭配完成一個具有衡量概念的關鍵問題之修正評選機制。在量化的評選作業之外，本研究也將技術可行性、人員接納性等等考量也納入評選機制中，以彌補評選過程中過度仰賴量化客觀性的可能缺失。

此外，本研究採用實驗室營運績效改善個案作為建構與修正此一機制的實證基礎，證明本機制足以協助問題管理者有效解決問題。

The key to effective problem solving lies in correct identification of the root cause. The TOC Problem Solving model employes the concept of Common Sense Management and utilizes the cause and effect relationship in search of the core causes of the problem. However, it bears the drawback of lacking measurement scheme. It is therefore hard to convince a problem solver whether or not the selected key problem is indeed the true key problem. As this important issue is in-negligible, we choose to pick this “key problem selection” issue as the core of this study and aim at establishing an effective and objective key problem selection scheme.

For this reason, we first targeted on the existing approach and methods which are employed by TOC in selection of key problem, and then formulated into a clear and comprehensible scheme. Furthermore, by incorporating the evaluation scheme of Analytical Hierarchical Process, we have re-established a revised TOC key problem selection scheme bearing the measurement concept. In addition to the quantifiable selection scheme, we have also adopted the considerations such as technical feasibility, acceptance of stakeholder etc, into the selection scheme, so as to diminish the potential problems due to over-reliance on rigid quantifiable objectivity.

Moreover, we have incorporated in this research a case study on “Improvement of performance of operation of a Laboratory”. This empirical study served as an important basis for establishing .It also verified the proposed scheme and revision of the proposed scheme is indeed a feasible one.
