SPC
SPC (Statistical Process Control) is a method used in manufacturing to monitor and control product quality. It's like having a quality detective that watches over production lines to catch problems before they become serious. Manufacturing companies use SPC to make sure their products meet customer requirements consistently. Think of it as a early warning system that uses charts and measurements to show when something in the manufacturing process might be going wrong. This helps reduce waste, save money, and keep customers happy by ensuring products are made correctly the first time.
