In aviation there are similar methods of doing checklists:

Say - Do: pilot not flying says the task, pilot flying verifies verbally after doing it.

Challenge - Response: challenge the check list, verbally respond (do the action)

Flow-Confirm: Do all required actions then verbally confirm.

In any case, the verbal and physical confirmation is needed to move on in the checklist.

When flying solo I do "Say-Do"
