What should be done after circling an out-of-specification reading?

The correct course of action, which combines reporting to a work supervisor and annotating the reading on the log, is critical for several reasons.

Reporting to a work supervisor ensures that the issue is communicated promptly to someone in a position to take appropriate action. This is vital because out-of-specification readings can indicate potential problems with equipment or processes that need to be addressed to maintain safety, compliance, and operational efficiency.

Annotating the reading on the back of the log provides a clear record of the occurrence, which is essential for tracking performance over time. This documentation can help in identifying patterns or recurring issues that may require deeper investigation or action. It also ensures accountability and maintains a log of operational history for quality control purposes.

By combining these two steps, the response demonstrates a comprehensive approach to quality management that is essential in engineering practices. This allows teams to maintain operational integrity and ensure all deviations from specifications are adequately addressed.
