Announce a release: the shift, what's new, proof and the rollout plan.
Speaker notes
The launch date and the promise in one line. Put the product name in the rail and keep the subtitle to what changes for the customer.
Name the old behaviour plainly, without straw-manning it. Three symptoms are enough; each one should be recognisable to the audience.
Three changes, each in the customer's words. If a feature needs a diagram, it belongs on its own slide, not this card.
Three performance claims with the test behind them. Put methodology in the notes, not on the slide.
Four weeks, four checkpoints. Say who is included at each step and what they should expect to change.
One customer sentence beats a wall of logos. Attribute it, and swap in a quote from a design partner you can name.
End on the date and one action. Replace the URL with the launch page, and keep the three columns to next steps only.
