Question

Quizplus · Accepted Answer

Cause-and-effect diagrams, also known as Ishikawa diagrams or fishbone diagrams, are a tool used to identify and organize potential causes of a problem or failure. They are often used in quality management systems to identify and respond to potential reasons of failure. Option B is incorrect because cause-and-effect diagrams do not indicate how frequently each type of failure occurs. Option C is incorrect because identifying random and nonrandom variations is typically done using statistical process control tools, not cause-and-effect diagrams. Option D is incorrect because evaluating the tradeoffs among prevention costs, appraisal costs, and failure costs is part of cost-benefit analysis, not cause-and-effect diagrams.
