Donald J. Wheeler

Donald J. Wheeler is an influential statistician known for his work in quality control and process improvement. He developed methodologies that help organizations understand and improve their processes using statistical tools. One of his key contributions is the control chart, which monitors variations in processes over time to identify problems. Wheeler emphasizes the importance of distinguishing between common cause variation (natural fluctuations) and special cause variation (specific issues) to improve quality effectively. His approaches have been widely adopted in manufacturing, healthcare, and other industries to enhance efficiency and produce better results.
