What is a major advantage of using control charts in process management?

Using control charts in process management is advantageous primarily because they monitor process variation over time. This capability allows organizations to visualize how a process performs, identifying trends, shifts, or any unusual variations that may indicate potential problems. By tracking this data over time, decision-makers can understand the stability and capability of their processes, leading to informed decisions regarding improvements or interventions.

Control charts provide real-time feedback about whether a process is in a state of statistical control and can highlight whether variation is due to common causes (inherent in the process) or special causes (which can be addressed). This ongoing analysis is crucial for maintaining quality and efficiency in processes, enabling teams to take actionable steps based on empirical data rather than assumptions.
