What and how to confirm
There are 2 types of things that might need to be confirmed:
Key pieces of information that were said or implied
Example: men’s running shoes (shoe style), royal blue and neon green (color)
Something the assistant is about to complete or has completed
Example: Adding a session to the user’s schedule
And there are 3 ways to handle them:
1) Explicit confirmation
Requires a response from the user to confirm (“Did I get the message right?”). Usually yes/no or some synonym.
2) Implicit confirmation
Does not require a response from the user, although users might give one if they want to make a correction. Simply confirms (“for 2 people sitting together”) and moves on.
3) No confirmation
No overt confirmation (of the zip code).
