Creating a control chart involves the following steps:
Select the Process: Identify the business process or operation you want to monitor. Collect Data: Gather data points over a specified period. Ensure the data is representative of the process. Calculate Control Limits: Compute the upper and lower control limits, typically set at three standard deviations from the process mean. Plot Data Points: Plot the data points on the chart along with the control limits. Analyze the Chart: Look for any points outside the control limits or patterns that suggest non-random variation. Take Action: If the chart indicates the process is out of control, investigate and take corrective actions.
