Choose the Control Charts for Each Quality Characteristic
Control charts help in visualizing the performance of quality characteristics over time and detecting any out-of-control patterns. By choosing the appropriate control charts for each quality characteristic, you can effectively monitor and control the process. Which control charts are suitable for monitoring the identified quality characteristics?

Determine the Sample Size and Sampling Frequency
The sample size and sampling frequency determine how often data will be collected for analysis. By determining the appropriate sample size and sampling frequency, you can ensure that you have enough data to make accurate conclusions about the process performance. What should be the sample size and sampling frequency for your quality control activities?
Establish Control Limits for the Charts
Control limits define the boundaries for acceptable variation in the process. By establishing control limits for the control charts, you can easily identify when the process is out of control and take corrective actions. What should be the control limits for the identified control charts?
Plot the Data on the Charts
This task involves collecting data for the identified quality characteristics and plotting them on the respective control charts. By regularly plotting data on the charts, you can monitor the process and identify any trends or patterns that indicate variation. Have you collected the data for the identified quality characteristics?
1
Yes
2
No
Analyse the Charts and Identify Out of Control Patterns
By analyzing the control charts, you can identify any out-of-control patterns that indicate a significant deviation from the expected process performance. This task involves reviewing the control charts, identifying any non-random patterns, and taking appropriate actions. Have you analyzed the control charts?
1
Yes
2
No
Investigate Potential Causes for out-of-control Patterns
When out-of-control patterns are identified, it is important to investigate the potential causes. By investigating the causes, you can address the root problems and prevent their recurrence. What could be the potential causes for the out-of-control patterns observed in the control charts?
Apply Corrective Measures if Necessary
After identifying the causes, it is important to apply corrective measures to bring the process back under control. By applying the appropriate corrective measures, you can prevent further quality issues and improve the process performance. What corrective measures should be applied based on the identified causes?
Retake Sample and Chart again
Sometimes, it is necessary to retake samples and chart the data again to ensure that the corrective measures have been effective and the process is under control. By retaking samples and charting the data, you can verify the effectiveness of the corrective measures. Should the samples be retaken and the data charted again?

Reassess Control Limits and Process Capability
After applying the corrective measures and verifying their effectiveness, it is important to reassess the control limits and process capability. By reassessing the control limits, you can ensure that they are still appropriate and reflect the current process performance. What should be the new control limits and process capability assessment?
Review and Adjust Sample Size or Sampling Frequency
Periodically reviewing and adjusting the sample size and sampling frequency is important to ensure that they are still appropriate for monitoring the process. By reviewing and adjusting these parameters, you can optimize the quality control activities. Should the sample size and sampling frequency be reviewed and adjusted?
1
Yes
2
No
Monitor the Control Charts Regularly
Regular monitoring of the control charts is crucial to detect any changes in the process performance and take timely actions. By monitoring the control charts at regular intervals, you can ensure that the process remains under control. How frequently should the control charts be monitored?
Retrain Personnel if necessary
Personnel training is essential for maintaining and improving the quality of the process. By retraining personnel when necessary, you can ensure that they have the required knowledge and skills to carry out their tasks effectively. Is there a need for personnel retraining?
1
Yes
2
No
Document all Quality Control Activities
Documenting all quality control activities is important for record-keeping and future reference. By documenting the activities, you can track the changes made, analyze their impact, and ensure compliance with quality standards. Are all quality control activities adequately documented?

Determine Need for Revised Process/Control Charts
Periodically evaluating the need for revised processes and control charts is crucial to accommodate changes in the product or process. By determining the need for revisions, you can ensure that the quality control activities remain relevant and effective. Is there a need for revised processes or control charts?
1
Yes
2
No
Plan and Implement Changes if needed
If revisions are required, it is important to plan and implement the changes effectively. By carefully planning and implementing the changes, you can minimize disruptions and ensure a smooth transition to the revised processes or control charts. What changes need to be planned and implemented based on the evaluation?
Evaluate the Impact of Changes
After implementing the changes, it is important to evaluate their impact on the quality characteristics and overall process performance. By evaluating the impact, you can determine the effectiveness of the changes and identify any further adjustments required. What is the impact of the implemented changes on the quality characteristics and process performance?
