Definition of Quality

Conformance to requirements 與需求相符 : meeting written specifications


A Simple HOQ （ House of Quality) Matrix

A matrix defines the relationship between the requirements of customer and product characteristic


An example of HOQ Matrix

A Detailed HOQ

客戶對商品之認知及比較

產品特性相互關係

Quality Function Deployment (QFD)品質功能部署之優點

常用之工具，製造及服務業皆然有系統的暸解客戶需求，並轉換成技術需求。便於提早確定產品特性，降低修改設計的風

險，減少產品之前置時間。利於單位間之協調與合作可借以開發出新產品


統計流程控制 Statistical Process Control (SPC)-Out of Control


•都在區間內，且接近平均值•上下比例大至相同•無不常之型態

統計流程控制 Statistical Process Control (SPC)-in Control


The Cost of Quality 品質成本Cost of conformance (COC): delivering produ

cts that meet requirements and fitness for use達到完成品符合需求，並適合使用所耗費的成本

Cost of nonconformance (CONC): taking responsibility for failures or not meeting quality expectations 負擔失敗或未能與品質期望相符責任的成本


Cost of Quality


Five Cost Categories Related to Quality Prevention cost: the cost of planning and executing

a project so it is error-free or within an acceptable error range 「預防成本」

Appraisal cost: the cost of evaluating processes and their outputs to ensure quality 「鑑定成本」

Internal failure cost: cost incurred to correct an identified defect before the customer receives the product 「內部錯誤成本」

External failure cost: cost that relates to all errors not detected and corrected before delivery to the customer 「外部錯誤成本」

Measurement and test equipment costs: capital cost of equipment used to perform prevention and appraisal activities 「衡量與測試設備成本」


品質成本（傳統 vs. 現在觀點比較）


Modern Quality Management

Six Sigma and Defective Units


DMAIC Define: Define the problem/opportunity, process,

and customer requirements Measure: Define measures, collect, compile, and

display data Analyze: Scrutinize process details to find

improvement opportunities Improve: Generate solutions and ideas for

improving the problem Control: Track and verify the stability of the

improvements and the predictability of the solution


Total Quality Management (TQM) Customers Define Quality Quality Leadership and Responsibility Strategic planning Continuous Improvement Cooperation Statistical methods Education


Quality Certification ( 品管認証） ISO9000


隨堂作業請以組為單位，選擇一開發生產之商品（可以和作業一之產

品相同），依課堂所授之 HOQ （ House of Quality) Matrix（ P4,5 ），繪製成表 :定義客戶對此商品之需求再依此需求決定產品之特性最後衡量各需求與各特性之關係，並統計各產品特性之

重要性。
