Six Sigma is a data-driven methodology used to improve business processes by reducing defects and variability.

• Six Sigma aims to achieve a level of quality where the probability of defects is extremely low.

• It uses statistical analysis to identify and eliminate sources of variation in a process.

• The methodology follows a structured approach called DMAIC (Define, Measure, Analyze, Improve, Control).

• Six Sigma is widely used...read more

Fishbone diagram is a visual tool used to identify the possible causes of a problem or an effect.
