TQM, PDCA, six-sigma and base lining

TQM (Total Quality Management), PDCA (Plan-Do-Check-Act), Six Sigma, and baselining are all important concepts in Software Quality Assurance (SQA).

TQM is an approach that focuses on continuous improvement of quality by involving all employees in the organization. This involves a focus on customer satisfaction, continuous improvement, and teamwork.

PDCA is a quality management framework that involves four stages: Plan, Do, Check, and Act. It is a cyclic approach that aims to improve processes and products continuously.

Six Sigma is a data-driven approach to quality management that aims to reduce defects and improve processes by identifying and eliminating the causes of errors or defects.

Baselining is the process of establishing a benchmark or reference point for quality. It involves defining the current state of quality and measuring improvements over time.

In SQA, these concepts are used to ensure that software products are developed and delivered with high quality. TQM and Six Sigma are used to establish a culture of quality in the organization, while PDCA is used to continuously improve processes and products. Baselining is used to establish quality metrics and measure improvements over time.

By using these concepts, SQA teams can identify potential quality issues early in the development process and take corrective actions to ensure that the software product meets the desired quality standards. This results in software products that are reliable, efficient, and effective in meeting the needs of their users.
