a method of cleaning a dirty needle. The auditor directs the pc to "fish" around or look things over. When a specific needle pattern shows up on the needle, he directs the pc's attention to it and continues to do so each time the same pattern shows up until the pc comes up with some information on it. Using this information the auditor "fumbles" around for a test What question that produces the specific pattern in question. The auditor then goes after the specific overt and, if necessary, cleans up the chain. See also What question in this glossary.—AcademyLevel 0 Glossary Approved 3-12-90
