Role playing in design asks participants to step into the shoes of a user, a service employee, or another actor in a system and to improvise their responses to a scenario in real time. It is a powerful empathy-building and idea-testing technique that brings abstract personas and journey maps to life and reveals interaction dynamics that no static diagram can capture. When teams act out scenarios before building them, they consistently discover problems, opportunities, and emotional dimensions that would otherwise surface only after significant investment.
What It Is
Design role playing involves assigning participants to roles relevant to a service or product scenario, giving them a brief scenario description, and asking them to improvise the interaction. Unlike bodystorming, which focuses on physical movement and spatial experience, role playing focuses primarily on the conversational and relational dynamics of an interaction: how a service representative and a customer navigate a complaint, how a doctor and a patient share difficult information, or how two colleagues use a shared digital tool to complete a task together. The improvised nature of role playing surfaces natural language, emotional reactions, and relational dynamics that scripted demonstrations miss.
How to Run It
Write two to three scenario briefs that describe a situation relevant to your design challenge. Assign roles to participants and give them a few minutes to read their brief and prepare. Set up the physical space to reflect the scenario context as closely as possible. Run the role play for five to ten minutes, then pause for a debrief. Ask observers what they noticed, ask participants what they felt and thought during the interaction, and identify the moments that felt most revealing. Run multiple scenarios with different participants to capture variation.
When to Use It
Role playing is particularly valuable in service design when the experience you are designing involves human-to-human interaction, such as customer service encounters, healthcare consultations, or educational experiences. It is also effective for testing the emotional and conversational dimensions of a proposed design concept before prototyping. Use it when journey maps and personas have been created but the team needs a more visceral, embodied understanding of the experience they are designing for.
Tips for Success
Establish psychological safety before the session begins. Role playing requires participants to be vulnerable in front of their colleagues, and that requires trust. Use a warm-up exercise that normalises performance and improvisation before moving into the design scenarios. Brief observers explicitly on what to watch for: emotional tone, moments of confusion, unmet needs, and places where the interaction feels awkward or strained. Debrief within thirty minutes of the session while observations are still fresh and emotions are still accessible.
