Define Done With an Example

Replace “it works” with one concrete input, action, and observable result.

Frame

The question

What exact example would prove the core workflow works?

Do this

  • Use real-looking values instead of placeholders.
  • Include the state before and after the action.
  • Let the example become an acceptance test later.

Example

  • Given one in-stock product at $20, a visitor adds two, pays successfully, and sees order #1042 for $40; the order is stored as paid.

Ask next

  • ?What is the initial state?
  • ?What changes?
  • ?What can a user or test observe afterwards?
