More on One to One Meetings

After practicing it as initiator for quite some time now, I feel the success of one-one lies in the inherent values present in the process itself.
1. Suits both Introvert and Extrovert behaviours: For people who are introvert or extrovert, one to one is an ideal setting. Extroverts can let go their feelings more forcefully while introverts will try to submissively but subtly put their points across.
2. Air of Confidence : News in the room is known to ONLY two people. So each of the parties know well who the source of any unwanted, unnecessary leakage is. Since it is a boss-subordinate relationship, it is always the respect for each that would make the sharing of news easier. This is important to be in "Sync with the ground realities" and getting the "pulse" of people before commitments made to the management.
3. Short and Sweet: This is something I used to like. It helped me improve my communication better. Whenever I need to ask a question to my remote boss or convince him of something closely affecting me, I felt the need for preparation to cover as much ground in the discussion within the available time. It helped me hypothesize situations and prepare statements that would lead to the points, I like to hear or get addressed.

Have you a good case to share for one to one meetings ?
