What do Quality Control Charts help identify in a business process?

Quality Control Charts are essential tools in the Lean Six Sigma methodology that allow businesses to visually monitor and analyze the stability and performance of their processes over time. The primary function of these charts is to determine whether a process is in a state of control, which means that it is predictable and consistent, or if it is being impacted by special causes of variation.

When a process is predictable, it follows a consistent pattern, and variation within the process can be attributed to common causes. Conversely, when a Quality Control Chart reveals points outside the control limits or an unusual pattern, it indicates the presence of special causes that require further investigation. Identifying these variations is crucial because it helps organizations respond effectively, determine when adjustments are needed, and ultimately improve process quality.

While other options mention aspects such as budget control, employee feedback, and customer demand, they do not directly relate to the primary function of Quality Control Charts in analyzing process stability and variations. Quality Control Charts focus specifically on process behavior and improvements, making them a vital component in quality management and continuous improvement efforts.
