Control Charts
Control charts are visual tools used in quality control to monitor how a process varies over time. They display data points collected from a process against predetermined upper and lower limits, called control limits. When the data points fall within these limits, the process is considered stable. If points fall outside these limits or show unusual patterns, it may indicate potential problems needing investigation. Essentially, control charts help organizations maintain quality by identifying variations that could affect performance or product quality, facilitating timely adjustments to keep processes on track.
