In 1924, Dr. Walter A. Shewhart changed the game with his invention: the Control Chart. Back then, checking quality meant waiting until the end of production to spot defects. Shewhart saw a better way. His Control Chart gave a visual way to monitor how processes were doing in real-time. By plotting data on a chart, workers could tell if things were going smoothly or if there were problems to fix.
Since then, the Control Chart has spread beyond factories. It's used in healthcare, finance, and more. It's like a universal tool for making things work better. Control charts are great detecting trends of statistical significance, tracking for example your fatigue risk exposure per rank, base and fleet using NFR.
As we mark its 100th birthday, let's remember how this simple chart has made big waves. It's not just about manufacturing anymore—it's about making everything run smoother, one chart at a time. Cheers to Dr. Shewhart and his game-changing invention!
