The purpose of the Johari window concept is to expand the open area of an individual through self-disclosure and feedback. Self disclose by the person expands the open area horizontally by contracting the facade or hidden area. Feedback from others expands the open area vertically by contracting the unknown area.
A new member in a team setting will invariably have a small arena and blind spot, and a large facade. As the member progresses in the team, others would get to know about their innate characteristics and traits, and pass it on to the team member as feedback, allowing him or her to increase arena at the cost of a blind spot. The member, as they work with others, reveals more about themselves as disclosure, again increasing the arena at the expense of the facade.
The disclosure and feedback in Johari windows is structured, and is through adjectives such as “able," “adaptable," “calm," “friendly," “independent," “ingenious," “knowledgeable," “nervous," “organized," “patient," “reflective," “religious," “assertive," “self-conscious," “sensible," “trustworthy," and others.
