Summary

• Stories have loads of hidden assumptions. The ones to worry about are those that will cause problems.

• To identify the potential problems:

  • Think about the system from the customer's viewpoint.

  • Think about the system from the programmer's viewpoint.

  • Identify the mismatches.

• Expect to ask lots of questions, but be disciplined. There's a limit.

• Ask tangential but targeted questions that allow the respondent to make connections and think of the details.

OK, now it's your turn to try these ideas out with an exercise.
