SPC
SPC (Statistical Process Control) is a method used to monitor and improve the quality of manufacturing and business processes. Think of it as a way to catch and fix problems before they become serious issues. It uses simple charts and graphs to track if a process is working correctly, much like how a doctor monitors a patient's vital signs. Companies use SPC to reduce waste, improve product quality, and save money. Similar terms you might see include Quality Control Charts, Process Control, or Statistical Quality Control. It's a key tool in quality improvement programs like Six Sigma and Lean Manufacturing.
