What is TQM? Meeting quality expectations as
defined by the customer
Integrated organizational effort designed to improve quality of processes at every business level

Defining Quality – 5 Ways Conformance to specifications
Does product/service meet targets and tolerances defined by designers?
Fitness for use Evaluates performance for intended use
Value for price paid Evaluation of usefulness vs. price paid
Support services Quality of support after sale
Psychological e.g. Ambience, prestige, friendly staff
![Page 5: Tqm 1](https://reader036.vdocument.in/reader036/viewer/2022081403/5549fc4cb4c905e56c8b4bbd/html5/thumbnails/5.jpg)

Manufacturing Quality vs. Service Quality
Manufacturing quality focuses on tangible product features Conformance, performance, reliability, features
Service organizations produce intangible products that must be experienced Quality often defined by perceptional factors
like courtesy, friendliness, promptness, waiting time, consistency

Evolution of TQM – New Focus
![Page 7: Tqm 1](https://reader036.vdocument.in/reader036/viewer/2022081403/5549fc4cb4c905e56c8b4bbd/html5/thumbnails/7.jpg)

TQM Philosophy – What’s Different?
Focus on Customer Identify and meet customer needs Stay tuned to changing needs, e.g. fashion styles
Continuous Improvement Continuous learning and problem solving, e.g. Kaizen, 6 sigma
Quality at the Source Inspection vs. prevention & problem solving
Employee Empowerment Empower all employees; external and internal customers
![Page 8: Tqm 1](https://reader036.vdocument.in/reader036/viewer/2022081403/5549fc4cb4c905e56c8b4bbd/html5/thumbnails/8.jpg)

TQM Philosophy– What’s Different? (continued)
Understanding Quality Tools Ongoing training on analysis, assessment, and
correction, & implementation tools Team Approach
Teams formed around processes – 8 to 10 people Meet weekly to analyze and solve problems
Benchmarking Studying practices at “best in class” companies
Managing Supplier Quality Certifying suppliers vs. receiving inspection
![Page 9: Tqm 1](https://reader036.vdocument.in/reader036/viewer/2022081403/5549fc4cb4c905e56c8b4bbd/html5/thumbnails/9.jpg)

Four Dimensions of Quality
Quality of design Determining which features to include in the final design
Quality of conformance to design Production processes are set up to meet design specifications
Ease of use Instructions, operation, maintenance, safety
Post-sale service Responsiveness, rapid repair, p.m., spare parts
![Page 10: Tqm 1](https://reader036.vdocument.in/reader036/viewer/2022081403/5549fc4cb4c905e56c8b4bbd/html5/thumbnails/10.jpg)

Cost of Quality Quality affects all aspects of the organization Quality has dramatic cost implications of;
Quality control costs Prevention costs Appraisal costs
Quality failure costs Internal failure costs External failure costs
![Page 11: Tqm 1](https://reader036.vdocument.in/reader036/viewer/2022081403/5549fc4cb4c905e56c8b4bbd/html5/thumbnails/11.jpg)

Cost of Quality – 4 Categories
Early detection/prevention is less costly May be less by a factor of 10

Ways of Improving Quality Plan-Do-Study-Act Cycle (PDSA)
Also called the Deming Wheel after originator Circular, never ending problem solving process
Quality Function Deployment Used to translate customer preferences to
design
Seven Tools of Quality Control Tools typically taught to problem solving teams
![Page 13: Tqm 1](https://reader036.vdocument.in/reader036/viewer/2022081403/5549fc4cb4c905e56c8b4bbd/html5/thumbnails/13.jpg)
13
PDSA Details Plan
Evaluate current process Collect procedures, data, identify problems Develop an improvement plan, performance
objectives Do
Implement the plan – trial basis Study
Collect data and evaluate against objectives Act
Communicate the results from trial If successful, implement new process
![Page 14: Tqm 1](https://reader036.vdocument.in/reader036/viewer/2022081403/5549fc4cb4c905e56c8b4bbd/html5/thumbnails/14.jpg)
14
PDSA (continued)
Cycle is repeated After act phase, start planning and repeat
process

Cause-and-Effect Diagrams
Called Fishbone Diagram Focused on solving identified quality problem
![Page 19: Tqm 1](https://reader036.vdocument.in/reader036/viewer/2022081403/5549fc4cb4c905e56c8b4bbd/html5/thumbnails/19.jpg)

Flowcharts Used to document the detailed steps in a
process Often the first step in Process Re-Engineering
![Page 20: Tqm 1](https://reader036.vdocument.in/reader036/viewer/2022081403/5549fc4cb4c905e56c8b4bbd/html5/thumbnails/20.jpg)

Checklist Simple data check-off sheet designed to
identify type of quality problems at each work station; per shift, per machine, per operator
![Page 21: Tqm 1](https://reader036.vdocument.in/reader036/viewer/2022081403/5549fc4cb4c905e56c8b4bbd/html5/thumbnails/21.jpg)

Control Charts Important tool used in Statistical Process
Control – Chapter 6 The UCL and LCL are calculated limits used to
show when process is in or out of control
![Page 22: Tqm 1](https://reader036.vdocument.in/reader036/viewer/2022081403/5549fc4cb4c905e56c8b4bbd/html5/thumbnails/22.jpg)
22
Scatter Diagrams A graph that shows how two variables
are related to one another Data can be used in a regression analysis
to establish equation for the relationship
![Page 23: Tqm 1](https://reader036.vdocument.in/reader036/viewer/2022081403/5549fc4cb4c905e56c8b4bbd/html5/thumbnails/23.jpg)
23
Pareto Analysis Technique that displays the degree of importance for each
element Named after the 19th century Italian economist Often called the 80-20 Rule Principle is that quality problems are the result of only a few
problems e.g. 80% of the problems caused by 20% of causes
![Page 24: Tqm 1](https://reader036.vdocument.in/reader036/viewer/2022081403/5549fc4cb4c905e56c8b4bbd/html5/thumbnails/24.jpg)
24
Histograms A chart that shows the frequency distribution of
observed values of a variable like service time at a bank drive-up window
Displays whether the distribution is symmetrical (normal) or skewed
![Page 25: Tqm 1](https://reader036.vdocument.in/reader036/viewer/2022081403/5549fc4cb4c905e56c8b4bbd/html5/thumbnails/25.jpg)

Why TQM Efforts Fail Lack of a genuine quality culture
Lack of top management support and commitment
Over- and under-reliance on SPC methods
![Page 32: Tqm 1](https://reader036.vdocument.in/reader036/viewer/2022081403/5549fc4cb4c905e56c8b4bbd/html5/thumbnails/32.jpg)

Highlights TQM focuses on serving the customer’s quality needs TQM uses continuous improvement, quality at the source,
employee empowerment, quality tools, teams, benchmarking, and supplier certification
Four dimensions: product/service design, conformance, easy of use, post-sale support
Quality costs; prevention, appraisal, internal & external failures QFD and Seven Quality Tools used in managing quality The MBNQA, Deming Prize, and ISO Certification help focus on
quality improvement and excellence The seven Quality Gurus all made key contributions
