Which diagram is also known as a Fishbone diagram?

The Fishbone diagram is commonly referred to as a Cause-and-Effect diagram because it visually represents the potential causes of a specific problem or effect. The structure resembles the skeleton of a fish, with the main problem outlined at the head and the various categories of causes branching off like bones. This diagram helps teams identify, explore, and display the root causes of issues systematically. Its use is prevalent in quality control and continuous improvement processes, as it encourages comprehensive brainstorming sessions and fosters collaborative problem-solving.

In contrast, the other options do not represent this type of diagram. A Closed-Loop Process refers to a system where outputs are fed back into the system as inputs for further processing. Calibration is the process of verifying and adjusting the accuracy of measurement instruments, while a Corrective Action Report documents the steps taken to address and resolve non-conformities or defects. These concepts, while important in quality management, do not relate to the visual structure and purpose of the Fishbone or Cause-and-Effect diagram.
