The banks that get the biggest results almost never send just one person. Culture change needs the room aligned — not one executive translating it back alone.
You already know what happens when one person comes back from a great event fired up — and nobody else in the building was in the room. The energy doesn't transfer. The blueprint gets diluted in translation. Bring your CFO, your Head of Retail, your board chair — whoever needs to hear this in the room, not in a recap email.
