Walter A. Shewhart

Walter A. Shewhart was an American engineer and statistician, known as the father of statistical quality control. In the 1920s, he developed the concept of control charts, tools that help monitor process variability and identify when a process is out of control. His work laid the foundation for modern quality management and influenced figures like W. Edwards Deming. Shewhart's ideas emphasize the importance of data in decision-making, leading to improved manufacturing processes and product quality. His contributions are essential in various fields, including engineering, manufacturing, and business management.
