Quality Function Deployment (QFD) and Failure Mode and Effect Analysis (FMEA)

Total Quality Management (TQM)

• A management approach focused on long-term success through customer satisfaction, achieved by integrating the business to achieve the required result.
• Quality is a journey starting from design, to conformance, and ends at better performance.

8 Principles of TQM

• Customer-focused
• Total employee involvement
• Process-centered
• Integrated system
• Strategic and systematic approach
• Continual improvement
• Fact-based decision making
• Communications

Implementing TQM

• Clarify vision, mission, and values
• Identify critical success factors (CSF)

Concurrent Engineering (CE)

• A collaborative approach that encourages all relevant disciplines to work together from the start of a project.
• Improves quality by:
  • Early problem detection
  • Better communication
  • Reduced time to market
  • Cost savings
  • Increased customer satisfaction

Quality Function Deployment (QFD)

• A method used in product management that develops a product by prioritizing consumer needs and preferences first.
• Integrates customer needs throughout the product development process.
• Emphasizes listening to customers' needs and wants before deciding what product features or services to create.

Failure Mode and Effect Analysis (FMEA)

• A structured, step-by-step approach to identifying and analyzing all conceivable failures in a product, process, design, or service.
• Identifies potential failure modes and their causes and effects.
• Prioritizes failures according to their consequences, frequency, and detectability.

Case Studies

• QFD: A company used QFD to develop a new tape product, incorporating customer needs into the design and manufacturing process, resulting in a better-designed product that satisfied customer needs.
• FMEA: An engineer used FMEA to identify potential failure modes in a product, enabling the team to design those failures out of the system, reducing development time and costs.
