This document discusses various quality frameworks including the Capability Maturity Model (CMM), Six Sigma, and Total Quality Management (TQM).
The CMM is a framework that helps software organizations gain control of their processes through five levels of process maturity. Six Sigma is a data-driven philosophy for reducing variation and defects. It emphasizes achieving six standard deviations between the mean and nearest specification limit. TQM is a customer-focused and process-oriented approach that aims for continuous improvement and achieving zero defects.
