A manager is trying to identify the root cause of a departmental problem by interviewing...

Repeatedly asking why the problem is happening until employees feel that they have analyzed the problem thoroughly

Claiming ignorance of the problem and asking questions that elicit employees' fullest knowledge of the topic

Asking questions that require more than a one-word answer and encouraging others to draw on their own experiences

Sharing expertise about the problem, and asking direct questions that help check for understanding of the problem and test for consensus
