Q4) (a)

List Quality Standards. Explain any one.

Quality Standards

  • ISO 9000
  • ISO 9001
  • Six Sigma
  • CMM

Six Sigma

  • Six sigma is “A generic quantitative approach to improvement that applies to any process”
  • Six Sigma is a disciplined, data-driven approach and methodology for eliminating defects in any process - from manufacturing to transactional and from product to service
  • To achieve six sigma, a process must not produce more than 3.4 defects per million opportunities
    • 4 Sigma 6210 defects per million opportunities
    • 5 Sigma 230 defects per million opportunities
  • Six sigma have two methodologies.
    • DMAIC (Define, Measure, Analyze, Improve, Control)
    • DMADV (Define, Measure, Analyze, Design, Verify)
  • DMAIC - Six Sigma
    • Define: Define the problem or process to improve upon related to the customer and goals
    • Measure: How can you measure this process in a systematic way?
    • Analyze: Analyze the process or problem and identify the way in which it can be improved. What are the root causes of problems within the process?
    • Improve: Once you know the causes of the problems, present solutions for them and implement them.
    • Control: Utilize Statistical Process Control to continuously measure your results and ensure you are improving
  • DMADV - Six Sigma
    • Define, Measure and analyze are similar to above method.
    • Design: Avoid root causes of defects and meet the customer requirements
    • Verify: To verify the process, compare the process with the standard plan and find differences
