Name the desired shift: from anger to acknowledgment, confusion to clarity, urgency to a plan. Decide what the agent should demonstrate—empathy statement, boundary setting, or option framing—then tighten the timer. When goals are explicit, feedback becomes specific, and confidence grows through visible, repeatable progress across sessions.
Use concrete details customers actually say: late fees that feel unfair, deliveries marked “completed” that never arrived, a relative’s medication delayed. Include tone cues like sighs or interruptions. These sensory anchors help role‑players inhabit reality quickly and respond with empathy, not defensiveness, even when stakes feel personal.
Safety enables honest stretch. Agree on respectful language, time‑outs, and the right to reset. Participants should never parody customers or colleagues; authenticity matters. Normalize learning out loud by celebrating small improvements, asking for do‑overs, and keeping recordings private. Courage grows when people know experiments will not be weaponized.
