Cost-Oriented QC and Process-Oriented QC; Which is more Desirable Approach?

본(本) 연구(硏究)에서는 품질관리(品質管理)의 추진(推進)을 비용(費用) 지향적(指向的)인 방법(方法)과 공정지향적(工程指向的)인 방법(方法)으로 대별(大別)하고 각각(各各)의 특징(特徵)을 설명(說明)함과 아울러 비교분석(比較分析) 하였다. 또 현장(現場) Q.C 담당기술자(擔當技術者)들이 품질관리(品質管理)를 실시(實施)함에 있어서 방향(方向)을 모색한다거나 현재(現在) 실시(實施)하고 있는 방법(方法)의 부당성(不當性)을 첵크하기 위한 기준(基準)을 비용함수(費用函數)로서 제시(提示)하였다.

This paper introduces two approaches of the cost-oriented QC and the process-oriented QC, and compares them on several aspects. The cost-oriented QC tries to assure the specified quality level by sampling inspection within minimum quality cost, while the process-oriented QC aims at realization of target value of quality specification through process adjustment when a product deviates from the target. But the final purpose of both approaches is on quality assurance for markets and consumers. After all, desirability is a question of quality cost. This paper suggests two of cost functions for decision making criterion.
