SPC control charts are essential quality control tools. Operators use them to measure, regulate, and make manufacturing processes consistent. By controlling processes, they can diminish variations that can hurt quality.
Control charts help manufacturers decide if their processes are in statistical control. They tell operators when to act, and they show process behaviors by displaying variation. Control charts that show out-of-control processes serve as indicators that corrections or changes should be made to an organization’s process parameters. Ultimately, this results in process and product consistency.
