EML 4550 Engineering Design Methods

• Design For Quality
• Engineering Design, by G.E. Dieter Chapter 12

Total Quality Management (TQM)

• Definition of quality the ability (degree of
  accomplishments/excellence) of a product or
  service to satisfy the requirements of
  clients/customers
• Total Quality Management (TQM) is a comprehensive
  and structured strategy to manage the quality of
  products and services by making improvements
  through continuous feedback and assessment.
• In recent years, TQM requirements have been
  defined by organization to adherent to
  established standards, such as the International
  Organization for Standardization's (ISO, 1946)
  standards series.
• ISO 9000 (1987, 2000) family addresses "quality
  management".
• ISO 14000 (1996, 2004) family addresses
  "environmental management

ISO Management System Standards

• Plan-Do-Check-Act is the operating principle of
  the ISOs management system standards
• Plan set clear objectives and develop plans
  accordingly
• Do implementation
• Check assessment based on pre-determined
  objectives and metrics
• Act continuous evaluations leading to subsequent
  improvements

Quality Management Principles

• The eight quality management principles for the
  revised ISO 90002000 series are
• Principle 1 Customer focus
• Principle 2 Leadership
• Principle 3 Involvement of people
• Principle 4 Process approach
• Principle 5 System approach to management
• Principle 6 Continual improvement
• Principle 7 Factual approach to decision making
• Principle 8 Mutually beneficial supplier
  relationships
• The next step

Quality Control Tools

• Quality Functional Deployment (QFD)
• Design for Manufacturing and Assembly (DFMA)
• Taguchi Method
• Failure Mode and Effect Analysis (FMEA)
• Statistical Process Control (SPC)
• Six Sigma
• DMAIC Define, Measure, Analyze, Improve, Control
  usually for existing processes
• DMADV Define, Measure, Analyze, Design, Verify
  for new processes
