Who is often considered the father of Statistical Quality Control (SQC)?

Walter A. Shewhart is recognized as the father of Statistical Quality Control (SQC) for his pioneering work in the use of statistical methods for quality control processes in manufacturing. In the 1920s, Shewhart developed the concept of control charts, which are tools for monitoring process variation and identifying when a process is out of control. His work laid the foundation for modern quality management and introduced the idea that quality should be measured statistically, enabling organizations to make informed decisions based on empirical data.

Shewhart's contributions included the establishment of the Plan-Do-Study-Act (PDSA) cycle, which emphasizes the iterative nature of quality improvement. This integrated approach to quality through the application of statistical methods revolutionized the field and influenced many subsequent quality experts, including Deming and Juran. While others like Juran and Deming expanded on quality concepts and practices, Shewhart’s foundational work in SQC makes him a central figure in its evolution and application in various industries.
