2 APPLYING COST OF QUALITY TO TOTAL QUALITY MANAGEMENT by Johnson Tan Swan San Sngapore 1.0 THE IMPORTANCE OF QUALITY 1.1 THE DEFINITION OF QUALITY Qualty has been defned n a varety of ways: Qualty s ftness for use Juran Qualty s conformance to requrements Crosby Qualty s correctng and preventng loss, not lvng wth loss Hoshn Qualty s a predctable degree of unformty and dependablty, at low cost and suted to the market Demng The totalty of features and characterstcs of a product, servce or process, whch bear on ts ablty to satsfy a gven need from the customer s vewpont Brtsh Standard 1.2 THE REAL CHALLENGE OF QUALITY The challenges n Qualty Technology and Management are ncreasng yearly. In the 1990s, all organzatons faced the ssues of mprovng product and servce qualty and enhance nnovaton. The dscplne of qualty has evolved and expanded rapdly from nspecton to company-wde qualty management. 1.3 THE RETURN ON QUALITY Globalsaton s one of the key trends n the busness world today. As busness operatng costs contnue to rse and nternatonal competton grows more ntense, all organsatons wll fnd t ncreasngly dffcult to compete on prce. They must mantan ther cost compettveness and ensure that the qualty of ther products and servces are meetng ther customer s requrements. COST OF QUALITY provdes a means to gauge the RETURN OF QUALITY n an organsaton, and how ths return mpacts the bottom lne. It can serve as a useful platform to reduce busness cost and ncrease compettveness. Pakstan Insttute of Qualty Control ( ICQI'2000) 2

4 2.0 INTERPRETATION OF COST OF QUALITY 2.1 GENERAL INTRODUCTION Cost of Qualty s generally known as the sum of costs ncurred to prevent nonconformances from happenng (Cost of Conformance) and the costs ncurred when nonconformance n products and system occurs (Cost of Non-Conformance). It was commonly known that poor qualty costs can go as hgh as 40% of sales. Planned mprovement actons can be taken to prevent these qualty problems and reduce the COST OF QUALITY sgnfcantly (COQ) through the adopton of such actons over a perod of one to two years. The savngs n COQ wll boost the bottom lne of the organsaton. 2.2 MAJOR COMPONENTS OF COST OF QUALITY (COQ) COQ s generally dvded nto costs assocated wth four categores of actvtes : PREVENTION COST These are the cost of any acton taken to nvestgate, prevent or reduce the rsk of non-conformty or defect. Example : Plannng, Preparaton, Tranng, Preventve Mantenance and Evaluaton. APPRAISAL COSTS These are the costs of evaluatng the achevement of qualty requrements ncludng the cost of verfcaton and control performed at any stage of the qualty loop. Example : Producton Tral, Test and Measurement. INTERNAL FAILURE COSTS These are the costs arsng wthn organsaton due to non-conformty or defects at any style of the qualty loop. Example : Costs of Scrap, Rework, Retest, Re-nspecton, Modfcaton, Downtme, Overtme, Correctve Acton and Redesgn. Pakstan Insttute of Qualty Control ( ICQI'2000) 4

5 EXTERNAL FAILURE COSTS These are the costs arsng after delvery to the customer due to non-conformtes or defects. Example : Equpment Falure, Downtme, Warranty, Admnstratve Costs n dealng wth Falure and Loss of Customer s Goodwll. 2.3 COST OF CONFORMANCE ( COC ) Both Preventve and Apprasal Costs are known as the Costs of Conformance..e. : The cost of dong thngs rght the frst tme. 2.4 COST OF NON-CONFORMANCE ( CONC ) Both Internal and External Falure Costs are known as the Costs of Non- Conformance..e. : The cost ncurred as a result of thngs not beng done rght the frst tme. 3.0 IDENTIFICATION OF COST OF QUALITY 3.1 IDENTIFICATION OF COST OF CONFORMANCE ( COC ) ITEMS Step 1 : Develop and Prepare Cost of Conformance ( COC ) Checklst : Preventon Plannng and Wrtng of Procedures and Instructons Apprasal In-comng Inspecton Vendor Assurance In-process Inspecton Process Capablty Studes Fnal Testng and Inspecton Qualty Tranng Producton Tral Qualty Improvement Programs Collecton, Analyss & Reportng of Qualty Data Materals consumed durng Inspecton and Testng Feld Performance Testng Step 2 : Evaluate The Identfed Cost of Conformance ( COC ) Items.

7 Whole Account Ths method requres gatherng exstng fnancal data from company accounts. If accounts are set up to capture costs, such as tranng and rework, nformaton from the accounts can be used to measure COQ. Unt Prcng Ths method s effectve when a defect or problem s recurrng. To use defect prcng, smply multply the cost of one defectve unt by number of defectve unts. Whole Person Ths method s used when people are employed strctly for the purpose of workng on or handlng defects. Labour / Resource Clamng Ths method nvolves calculatng actual expendture on a specfc actvty, such as the amount of tme spent by an employee performng a task or the amount of fnancal outlay for a one-tme expense. Ths nformaton mght come from tme sheet, vouchers or any other method for determnng exactly how much was spent. 5.0 BENEFITS ACHIEVED IN IMPLEMENTING COST OF QUALITY SYSTEM Acts as method for assessng the overall effectveness of the qualty programmes Act as a method for determnng problem areas and acton prortes Provdes a platform for measurement of return on nvestment Converts the varous performance ndcators used n the company nto a sngle unt-dollar Act as a common method for quantfyng qualtatve mprovements 6.0 DOCUMENTATION, TRAINING, COMMUNICATION AND IMPLEMENTATION It s necessary to document the requred changes of qualty actvtes n a recognsed Qualty Assurance Model or ISO 9000 Qualty System or an In-house TQM Manual wth a vew to tran and communcate wth all relevant personnel n mplementng the changes effectvely.

Intate approprate correctve and preventve acton as and when necessary. 9.0 A PRACTICAL APPROACH IN IMPLEMENTING COQ ACTIVITIES IN AN ORGANISATION Phase 01: Phase 02: Phase 03: Phase 04: Phase 05: Project Intaton and Preparaton Assessment of Current Busness Performance Project Organsaton and Assgnments Identfcaton of Major Cost of Conformance (COC) and Cost of Non-Conformance (CONC) Items.

Phase 08: Organse and Implement Qualty Improvement and Cost Reducton Programmes. Phase 09: Establsh Contnuous Improvement of The Cost of Qualty Performance. Phase 10: Conduct Qualty Audts regularly and Intate Document Changes In Response To Improvements made In Varous Processes CONCLUSION The goal of usng COQ s to ncrease preventon actvtes n order to elmnate nternal and external falures and to reduce apprasal actvtes. Reducton of COQ must be part of a sustaned qualty mprovement process n an organsaton headed by top management through a TQM Programme REFERENCES Introducton To Qualty Management, Assurance and Control By Gregory B.
