A good trait of all analysts is to retain a skeptical approach to everything. Things are often different than they appear. One of my teachers also suggested that people have their own private logic so they will be consistent even if they do not appear to be on the surface. We must delve into their private logic. Things must be all connected logically like points on a line. Not your logic but theirs. Another source of information is people’s background. How did they arrive at the place you find them? A person, who has always been in one role and now finds themselves in another or always been in the same role, will have quite different views of the role and the world; important information. Interviewing a manager who has been in the role three weeks or ten years will provide quite different information. A good analyst does not take things at face value. One must check understanding by asking the question another way. You will be surprised at the information you get.
