The Johari Window has been around for a while (b. 1955) and although it sounds eastern and mystical it gets the name from its co-inventors Joe and Harry. Originally, Joseph Luft and Harrington V. Ingham developed the idea to help people improve self-awareness and personal development, and also mutual understanding between individuals within a group. The Johari-like grid sets out situations where interlocutors may or may not know each other, and may or may not be expecting the event. The Johari window provides a quick way of buiding soft skills simulations to teach people how to extend knowledge of one situation to address related but unknown situations. Worth a read.
