495 views

A bad sigma level indicates poor quality control in a process. Sigma levels measure process accuracy, with higher levels denoting fewer defects. A bad sigma level (typically below 3) signals frequent errors and inefficiencies, leading to reduced reliability and increased costs. To improve, identify key problem areas, enhance monitoring, and implement quality improvement practices like Six Sigma methodologies to achieve higher accuracy and better outcomes.
