Measures how well a process can perform within limits based on short-term data (natural variation).

Six Sigma is a disciplined, data-driven methodology used to eliminate defects and reduce variation in any process. Statistically, achieving "Six Sigma" quality means a process produces fewer than 3.4 defects per million opportunities (DPMO) . It is often described as a philosophy, a goal, and a methodology for near-perfection. 2. Explain the difference between DMAIC and DMADV. Measures how well a process can perform within
Example: If 1,000 units each have 50 opportunities for a defect and you find 100 total defects, the DPMO is It is often described as a philosophy, a
Used when creating a new process or product design from scratch.
COPQ (Cost of Poor Quality) represents the financial impact of producing defects. It includes costs for rework, labor, lost opportunities, disposal, and loss of revenue. Reducing COPQ is a primary driver for initiating Six Sigma projects.
The formula for Defects Per Million Opportunities is:
