Six Sigma – Quality Standards
- Moreover, Six Sigma is “A generic quantitative approach to improvement that applies to any process.”
- “Six Sigma a disciplined, data-driven approach and methodology for eliminating 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.
- Also, 5 Sigma -> 230 defects per million
- 4 Sigma -> 6210 defects per million
- Moreover, Six Sigma has two methodologies
DMAIC (Define, Measure, Analyze, Improve, Control)
- 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: Moreover, Analyze the processor problem and identify the way in which it can improve. 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: Also, Utilize Statistical Process Control to continuously measure your results and ensure you are improving
- Several Software Packages available to assist in measuring yield, defects per million opportunities, etc.
DMADV: (Define, Measure, Analyze, Design, Verify)
- Define, Measure and analyze similar to above method.
- Design: Moreover, 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.
