Count sessions per week, diversity of participants, and number of phrases adopted in real meetings. Add quick pulse checks about confidence and perceived fairness. When numbers rise alongside anecdotal wins, you know the practice is reshaping culture, not just filling another agenda slot.
Anchor micro role-plays to existing moments: Monday kickoffs, retro warmups, or one-on-one openers. Create a shared library of favorite prompts. Celebrate monthly with a lighthearted showcase of before-and-after lines. Rituals keep energy high and normalize continuous improvement across teams and levels.
