Developments of Quality Control

• Quality Assurance
• Failure Testing
• Statistical Control
• Company Quality Management
• Total quality control

Quality Management in Supply Chain

• Total Quality Management
• an approach that seeks to improve quality and
  performance which will meet or exceed customer
  expectations
• Measured through Reliability, Maintainability and
  Safety
• Six Sigma
• a disciplined, data-driven approach and
  methodology for eliminating defects in any
  process -- from manufacturing to transactional
  and from product to service

4
Principles of Total Quality Management

• Executive Management Top management should act
  as the main driver for TQM and create an
  environment that ensures its success
• Training Employees should receive regular
  training on the methods and concepts of quality.
• Customer Focus Improvements in quality should
  improve customer satisfaction
• Decision Making Quality decisions should be
  made based on measurements

5
Principles of Total Quality Management

• Methodology and Tools Use of appropriate
  methodology and tools ensures that
  non-conformances are identified, measured and
  responded to consistently.
• Continuous Improvement Companies should
  continuously work towards improving manufacturing
  and quality procedures.

6
Principles of Total Quality Management

• Company Culture The culture of the company
  should aim at developing employees ability to
  work together to improve quality.
• Employee Involvement Employees should be
  encouraged to be pro-active in identifying and
  addressing quality related problems

7
Principles of Six Sigma

• To eliminate defects
• To reduce production and development costs
• To reduce cycle times and inventory levels
• To increase profit margin and improve customer
  satisfaction

8
Six Sigma Deployment

• DefineIdentify a suitable project based on
  customer needs and quality characteristics
• MeasureIdentify the key internal processes that
  influence the process, and measure the related
  defects
• AnalyzeDiscover what the defects are and
  identify solutions
• ImprovePrioritize and implement improvement
  opportunities
• ControlSet in place a control plan or system to
  sustain the improvement

Quality and Safety Infrastructure

• Communication standard
• HACCP for food quality and safety
• EICC for electronic industry
• FOIA for appeal industry
• Quality control technology
• RFID
• Nondestructive testing
• Nanotechnology in food industry

Case Study Is Lean Six Sigma A Winning Approach?

• Lean and six sigma are two important strategies
  in production but often exclusion of each other
  in practice
• Industrial pioneers such as Honeywell and 3M
  combined both Lean and Six Sigma

11
Lean and Six Sigmas Challenges

• Lean cannot bring a process under statistical
  control
• Six Sigma cannot dramatically improve process
  speed or reduce invested capital
• To be viewed as rival methodologies
• Some companies choose one or the other as their
  primary improvement method
• Some companies use both methods as very separate
  tool

12
Lean Six Sigmas Approaches

• Implement Lean and Six Sigma together and
  reinforce one another
• Use lean to streamline processes and eliminate
  waste, then use Six Sigma to improve the
  consistency and reliability of these processes

13
The Outcome

• Reduce the variability in value-adding processes
• Reduce the cost of complexity in complementary
  way

Discuss the following questions

• What problems do this case study address? How
  does Lean Six Sigma help solve these problems?
• What issues and challenges do manufacturing
  present? What can be done to address these
  issues?
• What are the business issues that should be
  addressed when company implemented Lean Six
  Sigma?
