What is the main objective of an SPC Chart?

The main objective of an SPC (Statistical Process Control) Chart is to analyze process performance by plotting control limits. SPC Charts are tools used in quality control processes to monitor and control a process over time. By plotting the data collected from the process against control limits, organizations can determine whether the process is operating within specified limits, identify trends, and recognize variations that may require further investigation.

Control limits help distinguish between common cause variation, which is inherent in the process, and special cause variation, which signals a deviation that needs corrective action. Thus, SPC Charts provide valuable insights that can lead to improved process efficiency, waste reduction, and consistent quality output.

In contrast, other options do not align with the primary goal of SPC. Increasing inspections may not necessarily improve process performance and could lead to excessive costs without addressing root causes. Limiting feedback opportunities undermines continuous improvement efforts, while emphasizing creativity over control can lead to inconsistencies and quality issues, which SPC Charts are meant to address.
