What is Quality?
“The quality of a product or service is a customer’s perception of the degree to which the product or service meets his or her expectations.”

Best-In-Class and World-Class
Customers’ expectations of quality are not the same for different classes of products or services.
Best-in-class quality means being the best product or service in a particular class of products or services.
Being a world-class company means that each of its products and services are considered best-in-class by its customers.

Quality Drives the Productivity Machine
If production does it right the first time and produces products and services that are defect-free, waste is eliminated and costs are reduced.
Quality management programs today are viewed by many companies as productivity improvement programs.

Other Aspects of the Quality Picture
Just-In-Time (JIT) manufacturing Product standardization Automated equipment Preventive maintenance

JIT Manufacturing
“A system of enforced problem solving” Lot sizes are cut In-process inventories are drastically reduced Any interruption causes production to stop Quality problems are immediately addressed The necessary teamwork contributes to increased
pride in quality

Elements of TQM
Top management commitment and involvement Customer involvement Design products for quality Design production processes for quality Control production processes for quality . . . more

Elements of TQM
Develop supplier partnerships Customer service, distribution and installation Building teams of empowered employees Benchmarking and continuous improvement
![Page 22: World class management](https://reader033.vdocument.in/reader033/viewer/2022061106/541384548d7f7294698b4652/html5/thumbnails/22.jpg)
22
Top ManagementCommitment and Involvement
Support must be genuine or TQM will be seen as just another passing fad
Fundamental changes must occur in the culture of the organization
Such fundamental changes are not easy, but are impossible without top management’s commitment and involvement
![Page 23: World class management](https://reader033.vdocument.in/reader033/viewer/2022061106/541384548d7f7294698b4652/html5/thumbnails/23.jpg)
23
Customer Involvement
Mechanisms to involve the customer Focus groups Market surveys Customer questionnaires Market research programs
Quality Function Deployment (QFD) Formal system for identifying customer wants Eliminate wasteful product features and activities
that do not contribute
![Page 24: World class management](https://reader033.vdocument.in/reader033/viewer/2022061106/541384548d7f7294698b4652/html5/thumbnails/24.jpg)
24
Designing Products for Quality
Designing for RobustnessProduct will perform as intended even if
undesirable conditions occur in production or in field.
Designing for Manufacturability (DFM)Products typically have fewer parts and can be assembled quickly, easily, and error-free.
Designing for ReliabilityManufacturing parts to closer tolerances. Redundant components where necessary.
![Page 25: World class management](https://reader033.vdocument.in/reader033/viewer/2022061106/541384548d7f7294698b4652/html5/thumbnails/25.jpg)
25
Designing and ControllingProduction Processes
The responsibility of producing products of high quality rests with the workers producing the product
Two types of factors introduce variation in production processes Controllable factors - can be reduced by workers
and management Uncontrollable factors - reduced only by
redesigning or replacing existing processes
![Page 26: World class management](https://reader033.vdocument.in/reader033/viewer/2022061106/541384548d7f7294698b4652/html5/thumbnails/26.jpg)
26
Process Capability
Process capability is a production process’ ability to produce products within the desired expectations of customers.
The process capability index (PCI) is a way of measuring that ability.
![Page 27: World class management](https://reader033.vdocument.in/reader033/viewer/2022061106/541384548d7f7294698b4652/html5/thumbnails/27.jpg)
27
Process Capability Index (PCI)
PCI = (UL - LL) / (6s)
UL = allowed upper limit of the product characteristic, based on customer
expect.LL = allowed lower limit of the product
characteristic, based on customer expect.
s = standard deviation of the product characteristic from the production
process PCI > 1.00 Process is capable of meeting customer
expectations. PCI < 1.00 Process is not capable.
![Page 28: World class management](https://reader033.vdocument.in/reader033/viewer/2022061106/541384548d7f7294698b4652/html5/thumbnails/28.jpg)
28
Example: Process Capability
In order for a certain molded part to be considered acceptable, the molding process must be conducted within a limited range of temperature. The lower limit is 455o and the upper limit is 465o.
Three molding machines being considered are A, B, and C with standard deviations of sA = 2.50, sB = 1.25, and sC = 1.75.
Which of these machines are capable of producing the part in accordance with the temperature requirements?
![Page 29: World class management](https://reader033.vdocument.in/reader033/viewer/2022061106/541384548d7f7294698b4652/html5/thumbnails/29.jpg)
29
Example: Process Capability
PCIA = (465 - 455) / (6(2.50)) = 10/15 = 0.67 PCIB = (465 - 455) / (6(1.25)) = 10/15 = 1.33 PCIC = (465 - 455) / (6(1.75)) = 10/15 = 0.95
Machine A is not capable, with a PCI below 1.00. Machine C falls slightly short of being capable. Machine B is capable of producing within specifications.

Developing Supplier Partnerships
Supplier becomes part of the customer’s TQM program
The relationship between the supplier and the customer becomes long-lasting and durable
![Page 31: World class management](https://reader033.vdocument.in/reader033/viewer/2022061106/541384548d7f7294698b4652/html5/thumbnails/31.jpg)
31
Customer Service, Distribution, and Installation
Packaging, shipping, and installation must be included in TQM.
Warehousing, marketing, and the distribution function must be committed to perfect quality.
Contact between the customers and the firm’s product must be planned and managed to provide satisfied customers.
![Page 32: World class management](https://reader033.vdocument.in/reader033/viewer/2022061106/541384548d7f7294698b4652/html5/thumbnails/32.jpg)
32
Building Teams of Empowered Employees
Employee training programs Employees at all levels are trained in quality.
Works teams and empowerment Workers are given the authority to act.
Quality at the source Workers are responsible for their own work.
Quality circles Small groups of employees who analyze and
solve quality problems and implement improvement programs.
![Page 33: World class management](https://reader033.vdocument.in/reader033/viewer/2022061106/541384548d7f7294698b4652/html5/thumbnails/33.jpg)
33
Benchmarking and Continuous Improvement
Benchmarking The practice of establishing internal standards of
performance by looking to how world-class companies run their businesses
Continuous Improvement The company makes small incremental
improvements toward excellence on a continual basis
![Page 34: World class management](https://reader033.vdocument.in/reader033/viewer/2022061106/541384548d7f7294698b4652/html5/thumbnails/34.jpg)
34
TQM in Services
Since many services are intangible, it is difficult to determine their quality
Customers set their own standards for services Perceived quality of service affected by the
surroundings Performance of service employees determines in
large part the quality of the services
![Page 35: World class management](https://reader033.vdocument.in/reader033/viewer/2022061106/541384548d7f7294698b4652/html5/thumbnails/35.jpg)

Wrap-Up: World-Class Practice
Quality begins when business strategy is formulated Quality is the weapon of choice to capture global
markets Quality drives the productivity machine Not depending on inspection to catch defects;
concentrating on doing things right the first time Committing tremendous resources to put in place
TQM programs aimed at continuous improvement
