QFD: Quality Function Deployment

MST326 lecture 4

Drivers for Quality Management

• fundamental foundation foreffective business practice isgood customer-supplier relationships

• After WWII, increasing requirement for inspection of products and documentation of procedureso defence (US MIL-Q-9858a and NATO AQAP)o space (NASA QSR)o nuclear and power generation

• At first, each customer would auditsuppliers practices and procedures

• need for a widely accepted single route to company-wide certification identified

• national standards for specific products define minimum specifications

Drivers for Quality Management

BS 5750 (1979)

• United Kingdom in 1979: BS5750 - Quality Management and Systems

• developed to permit a company to document its commitment to quality and the standard of its quality systems.

ISO 9000:1987 series• International Organisation for Standards

(ISO) adopted a series of quality standards, ISO 9000:1987

• based on BS5750

• strongly influenced by the US Department of Defence Military Standards (MILspecs).

• initial version was focused on quality control using retroactive checkingand corrective actions.

ISO 9000:1994 series• ISO 9000 was revised in 1994

• greater emphasis on quality assurance via preventive actions.

• required evidence of compliance with documented procedures

• tended to create a significant volume of associated procedure("do it as you document it") manuals and bureaucracy.

QS-9000

• Ford, Chrysler, General Motors and other automotive/truck manufacturers identified deficiencies in ISO9000:1994

• undertook a re-interpretation and extension to develop QS-9000

• additionally addressed continuous improvement, manufacturing capability and production part approval processes.

ISO9000:2000 series

• moved towardsprocess performance metrics

• reduced the need fordocumented procedureswhere clear evidence existsthat the process is working well.

ISO9000:2000 series• standards provide criteria for companies to

• "certify" their quality managemento recertification is required every three years

• achieve "registration" by third-party auditor.

• the systemo verifies practice and processeso provides objective 3rd party validationo enables benchmarking.

ISO9000:2000eight quality management principles

oCustomer focus o Leadership o Involvement of people o Process approach o System approach to management oContinual improvement o Factual approach to decision making oMutually beneficial supplier relationships o The next step

ISO9000:2000 series• Four primary

Quality Management Standards (QMS):o ISO 9000: QMS - Fundamentals and

Vocabulary (recommended reading) o ISO 9001: QMS - Requirements

(required standard) o ISO 9004: QMS - Guidance

for Performance Improvement (recommended reading)

o ISO19011: Guidelines on Quality and Environmental Auditing

ISO9000:2000 structure

• Four major sectionsoManagement ResponsibilityoResource Managemento Product RealisationoMeasurement, Analysis and Improvement

• Divided into 21 elements

ISO9000 structure I

Management Responsibility 1. management commitment

2. customer focus

3. quality policy

4. planning

5. administration

6. management review

ISO9000 structure II

Resource Management 7. provision of resources

8. human resources

9. facilities

10.work environment

ISO9000 structure III

Product Realisation 11. planning of realisation processes

12.customer-related processes

13.design and/or development

14.purchasing

15.production and service operations

16.control of measuring and monitoring devices

ISO9000 structure IV

Measurement, Analysis and Improvement 17.planning

18.measurement and monitoring

19.control of nonconformity

20.analysis of data

21. improvement

QMS costs

• costs of certification may be considerable.o Evans and Lindsay [page 137] suggest

• registration audit may cost US$10-40K• training and documentation of order of US$100K.

o recording of the activities of the companycan save money: the data used to

• inform individual changes• underpin continuous improvement programs• invaluable as evidence in the event of litigation

Consequent upon ISO9000...• DuPont

o increased on-time deliveries from 70-90%o decreased cycle times from 15 to 1.5 dayso increased first-pass yields from 72 to 90%o reduced number of test procedures by 1/3.

• Toronto Plastics (Canada)o reduced defects/1000 from 150 to 15 in 1 year

• Delcor Homes (Michigan builder)o reduced correctable defect rates

from 27.4 to 1.7 in just two years.

Other relevant standards I ...• ISO 10006 project management

• ISO 10007 configuration management

• ISO 10012 measurement systems

• ISO 10013 quality documentation

• ISO/TR 10014 managing economics of quality

• ISO 10015 training

• ISO 17799 security

• ISO 19011 auditing

Other relevant standards II ...

• ISO/TS 16949 automotive suppliers

• ISO 17021 part one: conformity assessment ... for bodies providing audit/certification of management systems

Other relevant standards III ...

• BS 8300:2001 Design of buildings and their approaches to meet the needs of disabled people

• BS 8887-1:2006 Design for manufacture, assembly, disassembly and end-of-life processing (MADE).General concepts,process and requirements

10. Glossary of terms used in design management

Product design for SMEs

• BS 7373-1:2001 Guide to the preparation of specifications.

• BS 7373-2:2001 Product specifications. Guide to identifying criteria for aproduct specification and to declaring product conformity

• BS 7373-3:2005 Product specifications. Guide to identifying criteria for specifying a service offering

Quality Function Deployment

• A systematic method for transferring customer wants/needs/expectations into product and process characteristics

• Developed by Shigeru Mizuno (1910-1989) and Yoji Akao (b.1928) in Japano hinshitsu kino tenkai

• Excellent tool for communication between cross-functional groups

• Provides a common basis foro Integrated Product Developmento Simultaneous Engineeringo Concurrent Engineering

• QFD work divides into four partsomarket analysis to establish needs and

expectationso examination of competitors abilitieso identification of key factors for successo translation of key factors into product and

process characteristics

• Conjoint Analysis (market survey)o potential customers asked to rank a

number of product conceptso important factors chosen by factorial design

with two levels(statistical design of experiments)

• Toyota halved design costs and reduced development time by 1/3 after starting to use QFD

• Analysis of competitor products shouldo go on continuouslyo subject them to same scrutiny as own

company products
