Total Quality Management
• Encompasses entire organization, from supplier to customer
• Stresses a commitment by management to have a continuing, companywide drive toward excellence in all aspects of products and services that are important to the customer

The Quality Hierarchy
Inspection• The ad – hoc physical check of products or
goods or services to establish their compliance to specification
• “Quality” introduced after the production of the goods or services
• Does not examine cause and effect of poor quality
• Done by remote third party– Does not empower or make quality
part of the producers responsibility• Requires physical intervention• Limited to checking and proving that item
only– Defects are easily missed unless
100% checking or sampling techniques applied
• Often limited to the sensitivity of the testing process or ‘testability’ of the characteristics under examination
Quality control• The systematic checking of outputs from
or during a productive process• “Quality” introduced after the production
of the goods or services– More systematic
• Still done by remote third party• Requires physical intervention• Limited to checking and proving that item
only– Defects are easily missed unless
100% checking or sampling techniques applied
• Often limited to the sensitivity of the testing process or ‘testability’ of the characteristics under examination
The Quality Hierarchy
Assurance• A practical implementation of a total
quality approach– Requires total company commitment
• Strategic quality principle– Requires total company commitment
• Quality introduced at the outset and throughout the process
– Builds quality in• Quality becoming the responsibility of the
producer• Quality as part of the process• Administered and policed by remote third
party
Total Quality Management (TQM)• A total company approach to quality• Strategic top down strategy
– Used when quality is a key competitive advantage
• As much a philosophy as a technique– Customer is king– Build in rather than inspect in– Empowerment of the producer
• Demming as pioneer• Japanese as exemplars of approach

Total Quality Management ConceptsSix Sigma
Total Quality Management ConceptsEmployee Empowerment
Getting employees involved in product and process improvements
85% of quality problems are due
to process and material Techniques
Build communication networks that include employees
Develop open, supportive supervisors Move responsibility to employees Build a high-morale organization Create formal team structures
Total Quality Management ConceptsBenchmarking
Selecting best practices to use as a standard for performance
1. Determine what to benchmark
2. Form a benchmark team
3. Identify benchmarking partners
4. Collect and analyze benchmarking information
5. Take action to match or exceed the benchmark
Total Quality Management ConceptsJust In Time (JIT)
Relationship to quality:
JIT cuts the cost of quality JIT improves quality Better quality means less inventory
and better, easier-to-employ JIT system
Total Quality Management ConceptsJust In Time (JIT)
‘Pull’ system of production scheduling including supply management
Allows reduced inventory levels Inventory costs money and hides process and material problems
Encourages improved process and product quality

Total Quality Management ConceptsTaguchi Concepts
Engineering and experimental design methods to improve product and process design Identify key component and process variables
affecting product variation
Taguchi Concepts Quality robustness Quality loss function Target-oriented quality
Total Quality Management ConceptsQuality Robustness
Ability to produce products uniformly in adverse manufacturing and environmental conditions Remove the effects of adverse conditions Small variations in materials and process
do not destroy product quality
Total Quality Management ConceptsQuality Loss Function
Shows that costs increase as the product moves away from what the customer wants
Costs include customer dissatisfaction, warranty and service, internal scrap and repair, and costs to society
Traditional conformance specifications are too simplistic

Total Quality Management ToolsStatistical Process Control (SPC)
Uses statistics and control charts to tell when to take corrective action
Drives process improvement Four key steps
Measure the process When a change is indicated, find the assignable cause Eliminate or incorporate the cause Restart the revised process
Total Quality Management ToolsStatistical Process Control (SPC)
Total Quality Management ToolsInspection
Involves examining items to see if an item is good or defective
Detect a defective product Does not correct deficiencies in process
or product It is expensive
Issues When to inspect Where in process to inspect
Total Quality Management ToolsWhen and where to inspect?
1. At the supplier’s plant while the supplier is producing
2. At your facility upon receipt of goods from the supplier
3. Before costly or irreversible processes
4. During the step-by-step production process
5. When production or service is complete
6. Before delivery to your customer
7. At the point of customer contact
Total Quality Management ToolsSource Inspection
Also known as source control The next step in the process is your
customer Ensure perfect product
to your customer

Total Quality Management in Service
Service quality is more difficult to measure than the quality of goods
Service quality perceptions depend on Intangible differences between products Intangible expectations customers have of
those products
Total Quality Management in Service
The Operations Manager must recognize:
1. The tangible component of services is important
2. The service process is important
3. The service is judged against the customer’s expectations
4. Exceptions will occur
