What type of document communicates information about a corrective action?

A Corrective Action Report is specifically designed to document and communicate the details of a corrective action taken in response to identified issues or non-conformities. This document typically includes information such as the nature of the problem, the root cause analysis, the corrective actions implemented, and the effectiveness of those actions over time. Its primary purpose is to ensure that all relevant stakeholders are informed about what corrective measures have been put in place, enabling better tracking and accountability in the quality management process.

The other options do not serve the same primary function. A Calibration Report deals with the verification of equipment accuracy, while an X Bar Chart is a statistical tool used for quality control to monitor process variations. A Closed-Loop Report is generally related to processes that include feedback mechanisms but is not solely focused on corrective actions. Hence, the Corrective Action Report is the most appropriate document for communicating information specifically about corrective actions taken in a manufacturing context.
