What are the advantages and disadvantages of Control Chart?

Control charts are valuable tools for monitoring process stability and variations over time. Advantages include their ability to identify trends, detect out-of-control conditions early, and facilitate continuous improvement. However, disadvantages include the potential for misinterpretation if users are not properly trained, and they may require a significant amount of data to be effective. Additionally, they can be sensitive to variations that may not be relevant to the process, leading to unnecessary interventions.
