Questions and Answers

What is the purpose of conducting a Failure Mode and Effect Analysis (FMEA)?

  • To increase production problems in the design phase
  • To identify potential failure modes and design them out early (correct)
  • To reduce customer satisfaction with the final product
  • To slow down the development time and increase costs

Who typically guides the team in creating an FMEA?

  • An external consultant
  • The engineer's manager
  • The team leader (correct)
  • The customer

What is one benefit of creating a successful FMEA?

  • Identifying potential failure modes early (correct)
  • Increasing resource expenditure
  • Designing failures into the system
  • Slowing down the development time

Study Notes

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.
