W. Edwards Deming

American statistician and management consultant who taught Japanese manufacturers quality control after WWII (helping create the Japanese economic miracle) and developed Total Quality Management — whose 14 Points and System of Profound Knowledge became the foundation of modern quality and continuous improvement movements.

Created the statistical basis for continuous quality improvement — Deming's insight that most quality problems (85%+) are management problems (poorly designed systems) rather than worker problems fundamentally reframed organizational improvement: fix the system, not the person; his PDCA cycle (Plan-Do-Check-Act) became the foundation of lean, agile, and DevOps.
