Shut The Door

If you constantly find it difficult to get a full day's work into you day due to phone calls and interruptions from your people in the office, try the shut-door-policy for a couple of hours. Schedule a closed-door meeting with yourself in the calendar. Manage the expectations from your co-workers and the switchboard operator by explaining that you are busy in a meeting between, say 10 to 12. Put a sign on the door and bring the pieces of work where you need full concentration of efforts to complete into the meeting.
