Johari Window
The Johari window is a technique used to help people understand themselves and others better. It is a feedback model used in self-help groups and corporate settings to improve individual and team performance.
In the Johari window method, participants get a list of 56 adjectives and pick five or six they feel best describe their own personality. Colleagues do the same for that person.
The answers then get mapped onto a grid of four boxes. Once the grid is filled in, the participant and the other contributors get a chance to tell each other about the adjectives that only they picked.
