Takumi Costs of Quality
A Japanese character Prevention costs - reducing the
that symbolizes a potential for defects
broader dimension Appraisal costs - evaluating
than quality, a deeper products, parts, and services
process than
Internal failure - producing defective
education, and a more
parts or service before delivery
perfect method than
persistence External costs - defects discovered
after delivery

TQM Deming’s Fourteen Points
1. Create consistency of purpose
Encompasses entire organization, 2. Lead to promote change
from supplier to customer
3. Build quality into the product; stop
Stresses a commitment by y depe d g o
depending on inspections
spect o s
management to have a continuing, 4. Build long-term relationships based on
companywide drive toward performance instead of awarding
excellence in all aspects of products business on price
and services that are important to the 5. Continuously improve product, quality,
customer and service

Employee Empowerment Quality Circles
Getting employees involved in product
and process improvements Group of employees who meet
85% of quality problems are due regularly to solve problems
to process and material
Trained in planning, problem
Techniques solving, and statistical methods
l i d t ti ti l th d
Build communication networks
that include employees Often led by a facilitator
Develop open, supportive supervisors Very effective when done
Move responsibility to employees properly
Build a high-morale organization
Create formal team structures

Benchmarking Best Practices for Resolving
Selecting best practices to use as a Customer Complaints
standard for performance
Best Practice Justification
1. Determine what to Make it easy for clients It is free market research
benchmark to complain
Respond quickly to It adds customers and loyalty
2. Form a benchmark team complaints
Resolve complaints on It reduces cost
3. Identify benchmarking partners first contact
4. Collect and analyze benchmarking Use computers to Discover trends, share them, and align

Inspection When and Where to Inspect
Involves examining items to see if 1. At the supplier’s plant while the supplier is
an item is good or defective producing
2. At your facility upon receipt of goods from
Detect a defective product the supplier
Does not correct deficiencies in 3. Before costly or irreversible processes
process or product
4. During the step-by-step production
It is expensive process
Issues 5. When production or service is complete
When to inspect 6. Before delivery to your customer
Where in process to inspect 7. At the point of customer contact

Service quality is more difficult to The Operations Manager must
measure than the quality of goods recognize:
Service quality perceptions depend 1. The tangible component of
