1. Traditional Views on Quality
To many organizations, quality is regarded as conformance to standards.
To others, however, quality lies in the eyes of the beholdersbeholders.
Typically, quality may constitute by a number of attributes …such as. .. (to p4)

Traditional Views on Quality
• Evans and Lindsay (2002) suggest five different perspectives:
Judgmental – goal/image in mind
product-based – emphasis on production attributes
user-based – driven by the users’ needs
value-based – usefulness or satisfaction at a lower price
manufacturing-based – conformance to specifications
All these attributes are serving as the “result” of the outcome of products/services.

2. Traditional Views /History on Quality Management
However, QM is a set of attributes serving as an “input” factor to quality, and that it can be evaluated based on four stages of approaches (Garvin (1988)):
1. inspection,
2. statistical quality control,
3. quality assurance, and
4. strategic quality management. Since, TQMTQM was then used as a format to study quality

Traditional Views on Quality Management
Wilkinson and Witcher (1993) defined TQM with three simple equations :
• Total = participation of everyone,• Quality = meeting customer requirements
exactly, and• Management = enabling conditions for total
quality.
Still then, TQM is still mainly emphasizing ..Wilkinson, A., and Witcher, B., “Holistic TQM must take account of politic
process,” Total Quality Management, 4(1), 1993, pp.47-56.

Traditional Views on Quality Management
In the traditional quality management paradigm, firms are concerned with company-centeredcompany-centered issues such as price, product quality, and delivery time.
Conventional way that differs from SCM …… do you know what then SCM emphasized in our last few lecture??
Evident of proof of these traditional views of QM …

Traditional Views on Quality Management
• Optional Internet Assignment: Visit and explore the Internet site for the American Society for Quality (http://www.asq.org). Review the past issues of Quality Management Journal, select one article from the site, give a brief summary of what the article is about, and provide the complete citation of the article.

3. Defining Supply Chain Quality
In the 21st century global village, competitive priorities have been shifting away from traditional enterprise-centered concerns such as productivity and quality toto system-wide operational efficiency, and overall supply chain quality and success.
In such, when quality applies to SC, it gives .. (to p11)

Defining Supply Chain Quality
• Supply Chain Quality (SCQ)
• SC = a production-distribution network,
• Q = meeting market demands correctly, and achieving customer satisfaction rapidly, and profitably
• Again, in comparison to TQM, SCQ is ..(to p12)

TQM in general is input factors.
and
SCQ is the result.
How is then these related to SCQM? (note that, SCQM is also an input factors to SC)

Revision of Deming’s 14 Principles in SCQM (pp. 167-168)
• 1. Create its objective and involve everyone along the chain to win• 2. Adopt new philosophy and practices, such as use of IT as a competitive tool• 3. upstream information from suppliers and downstream information to customers• 4. stop making decision based on the basis of price tag• 5. keep improving event 3 above• 6. all parties should be involved in training in using statistical thinking approach• 7. provide guideline as to how to do more jobs with lesser resources required• 8. Drive out fear that no one should be blamed for any failed results• 9. working toward long-term relationship with suppliers• 10. Prepare trading partners to deal with problem of tomorrow.• 11. Focus on expanding the market• 12 Pride of workmanship for all trade partners• 13. Continuous improvement at the aim of quality and technology enhancement• 14. Involved everyone to work together to make a change.

Best Practices
• Optional Internet Assignment: Lands’ End has posted its eight principles of doing business in its Web site. Those principles center on product quality, pricing strategy, service guarantee, delivery service, customer focus, supplier capability, process efficiency, and unconditional promises. Visit and explore Lands’ End’s Web site (www.landsend.com) and show how those principles can be employed to help organizations to excel on all dimensions of supply chain quality.

6. Deming’s PDCA Cycle
Deming’s PDCA is referred to:• Plan – conceptual design of quality
• Do – Piloting quality
• Check – verifying quality
• Act – implementing quality
• Our goal is to apply this concept in SCQM that involved all trading partners Deming’s PDCA cycle and SCQM Tools (see

1. SCQM practices in Taiwan and Hong Kong
• Kuei et al. (2002) support the notion that how well quality and technology are introduced and managed within the framework of the social and technical systems of a supply chain is the key to increased quality and supply chains’ overall success.
Kuei, C., Madu, C. N., Lin, C., and Chow, W.S., “Developing supply chain strategies based on the survey of supply chain quality and technology management,” The International Journal of Quality & Reliability Management, 19(7), 2002, pp.889-901. (to p24)
26
Experiences of organizations like IBM, Toyota, and Ritz-Carlton Hotel have shown that the practices of quality management do have significant impacts on key aspects of social systems.
The Social Side
(to p24)
27
The Technical Side
Experiences of organizations like Bank of New York and Domino’s Pizza have also shown that Enterprise Resource Planning (ERP) is important to provide specific functionality to achieve integration of the technical systems in the supply chain environment.

8. Questions to Ponder
• How does “Best Buy” address supply chain quality issues?
• How does “Wal-Mart” address supply chain quality issues?
• How does “Lands’ End” address supply chain quality issues?

9. New Initiatives
• Optional Internet Assignment: Search on-line for the term Lean Six Sigma and compare this initiative with that of SCQM.
• Optional Internet Assignment: Visit and explore the Internet site for the Six Sigma Academy (http://www.6-sigma.com). What is the definition of Six Sigma? What are the key objectives of this initiative? What is its significance to any organization? What does it involve?
