What is the objective of an SPC chart?

The objective of a Statistical Process Control (SPC) chart is to analyze process performance. SPC charts are tools used in quality control that allow organizations to monitor a process over time. By plotting data points sequentially, these charts help identify variations in the process that could indicate potential issues or areas for improvement. When a process shows signs of variation outside of established control limits, it may signal that corrective actions are needed to maintain quality and efficiency.

Monitoring process performance through SPC enables organizations to make data-driven decisions to stabilize and improve processes, leading to increased quality and consistency in products or services. In contrast, other options focus on outcomes that are not directly related to the primary function of SPC charts, such as increasing speed or reducing workforce size, which do not address the overarching goal of understanding and controlling process variations.
