How to Facilitate a Johari Window Team Exercise

Why Use the Johari Window for Team Building?

A team's effectiveness depends largely on the level of trust and quality of communication among its members. The Johari Window provides a structured framework that helps team members explore differences in perception within a safe environment. By comparing self-assessments with peer assessments, each member can see concretely how large their Arena (Public Self) is and where their blind spots lie, rather than relying on abstract discussion. This data-driven self-awareness generates deeper understanding and connection than typical team-building games.

Research shows that the larger the Arena quadrant among team members, the higher the team's psychological safety, collaboration efficiency, and capacity for innovation. The core goal of a Johari Window team exercise is to expand each member's Arena through self-disclosure and constructive feedback. This not only improves individual self-awareness but also lays the cultural foundation for open and honest communication within the team.

If you are not yet familiar with the theoretical basis of the Johari Window, we recommend reading the Complete Johari Window Guide first. Understanding the four-quadrant model will make planning your team exercise much smoother.

Preparation

The ideal group size is 5 to 20 people. Too few participants will result in insufficient peer assessment data to reveal meaningful patterns; more than 20 people requires splitting into smaller groups, otherwise the discussion phase becomes lengthy and hard to manage. For teams larger than 20, we recommend dividing into groups of 5-8 with a designated facilitator for each group.

For time planning, the basic process takes 45 to 90 minutes. A streamlined version (self-assessment, peer assessment, and results review only) takes about 45 minutes; the full version (including in-depth discussion and action planning) should be allotted 90 minutes. Schedule the session when the team is most alert — avoid post-lunch slots or the end of the day.

Materials needed include: an internet-connected device for each participant (phone or computer), a projector (for explaining the rules and showing examples), and a whiteboard or flip chart (for capturing key points during discussion). For online sessions, you will need a stable video conferencing platform and an online collaborative whiteboard tool. Before the session, the facilitator should complete a full test run to become familiar with the workflow and anticipate potential issues.

Step-by-Step Facilitation Guide

Below is the complete five-step facilitation process. Each step includes specific instructions and suggested timing. Feel free to adjust based on your team's actual situation.

Step 1: Setting the Scene and Ground Rules

Spend 5-10 minutes introducing the team to the basic concepts of the Johari Window and the meaning of the four quadrants. Emphasize that the purpose of this exercise is to deepen mutual understanding — not to evaluate or judge anyone. Clearly state three ground rules: first, all feedback is anonymous; second, respect everyone's feelings and do not mock or comment on others' results; third, everyone has the right to choose how much of their results they share. Establishing psychological safety is the foundation for the entire exercise's success.

Step 2: Self-Assessment

Have each member complete their self-assessment using the online test tool by selecting the words from the trait list that they feel best describe themselves. This step typically takes 5-10 minutes. Remind participants to answer honestly, choosing traits that truly fit who they are rather than who they aspire to be. After completing the self-assessment, each member receives a unique link to share with other members for peer assessment.

Step 3: Peer Assessment

Each member shares their peer assessment link with the rest of the team. Everyone completes a peer assessment for every other member, selecting the words from the same trait list that they feel best describe that person. This is the most time-consuming step and typically takes 15-30 minutes depending on team size. The facilitator should set a clear deadline and provide periodic time reminders.

Step 4: Reviewing Results and Discussion

Once all peer assessments are completed, guide each member to view their Johari Window results. Allow 5 minutes of personal reflection time so everyone can privately review their four-quadrant distribution. Then move into the team discussion phase, inviting volunteers to share one or two findings that surprised them or gave them new insight. The facilitator can share their own results first as a model, lowering the psychological barrier for others to share.

Step 5: Action Planning

Guide each member to create one specific action item based on their results. This could be "I want to consciously work on a blind spot that was identified over the next month" or "I want to share my thoughts more proactively with the team to expand my Arena." Have everyone write down their action plan and encourage them to find a team buddy for mutual accountability. Close with a brief wrap-up thanking everyone for their participation and openness, and schedule a follow-up check-in.

Discussion Questions and Facilitation Tips

Good discussion questions guide the team from surface-level results to meaningful reflection. Here are several recommended questions: "What surprised you most about your results?", "Among the blind spots you discovered, were there any you had vaguely sensed before but never confirmed?", "What can the team do to help each other expand our Arenas?", and "What new insight did this exercise give you about a colleague?" These questions start from personal feelings and gradually lead toward team-level improvement.

The facilitator's role is not that of an expert but of a guide. Key facilitation tips: first, stay neutral and avoid making value judgments about anyone's results; second, respond positively when someone shares, for example "Thank you for being willing to share that"; third, read the emotional temperature of the room and check in privately with anyone who appears uncomfortable rather than pressing them publicly; fourth, manage time to ensure no segment runs over; fifth, use open-ended questions instead of closed ones to encourage deeper expression.

If the discussion leads to a deeper conversation about blind spots, direct members to the Blind Spots Guide to help them understand how blind spots form and how to respond constructively.

Online vs In-Person Exercises

The advantage of in-person sessions lies in the quality of face-to-face interaction. Body language, eye contact, and real-time emotional responses all enhance the depth and trust of the discussion. When team members are sitting in the same room, the atmosphere during personal sharing is warmer and more supportive. In-person sessions also make it easier to use visual aids like whiteboards and sticky notes to capture discussion highlights. The main limitation is that all members must be in the same location at the same time, which can be difficult to arrange for geographically distributed teams.

The greatest advantage of online sessions is flexibility. Remote and cross-regional teams can all participate, and the online test tool itself runs in the browser with no additional equipment required. However, the discussion phase of online sessions requires more deliberate design. We recommend using breakout rooms to split large teams into groups of 4-6 for deeper conversation, avoiding the common pitfalls of awkward silence or a few voices dominating the whole group. Additionally, use online whiteboard tools such as Miro or FigJam so participants can visually record their discoveries and action plans.

Regardless of which format you choose, the core value of a Johari Window team exercise remains the same: fostering self-awareness and team communication. For more strategies on applying the Johari Window in the workplace, see the Workplace Application Guide.
