Johari Window
The four windows
The model divides knowledge into four quadrants along two axes: what the person knows about themselves and what others know about them.
| Known to me | Unknown to me | |
|---|---|---|
| Known to others | Arena (open) Information that is shared and visible to everyone. This is the area of effective communication. | Blind spot Behaviors or traits that others see in me but I do not perceive. Feedback expands this area. |
| Unknown to others | Facade (hidden) What I know about myself but do not share with others. Trust reduces this area. | Unknown Aspects no one is aware of: undiscovered potential, unconscious motivations. Self-development and exploration reduce this area. |
How It Is Used in Agile Teams
The goal when working with the Johari Window is to expand the Arena (open) area: the larger the arena, the more effective the team's communication.
Two mechanisms expand the arena:
- Giving and receiving feedback: shrinks the blind spot. What others see and I don't perceive becomes visible when the team has a culture of honest, safe feedback.
- Openness and self-disclosure: shrinks the façade. When people share more about their motivations, fears, or limitations, the team can collaborate with more real context.
Both mechanisms require psychological safety as a precondition.
In the Retrospective
The retrospective is a natural space for working with the Johari Window: techniques such as ESVP, Appreciations, or Helped Hindered Hypothesis expand the team's arena by creating formal opportunities for feedback and self-disclosure.
Common mistake
Sharing blind spot feedback without first building trust. Honest feedback about someone's blind spots can be very valuable or very harmful, depending on the team's level of trust and psychological safety. Forcing feedback about unperceived behaviors on a team without psychological safety breeds defensiveness instead of learning.
