An experienced team who knows what you are trying to achieve often proposes a cheaper route to it; one who only sees the requirements as given prices your assumptions along with the work.



Define what is included as user stories or scenarios: a walk through each important path. Equally important, write down what the first release deliberately excludes.

List the constraints.
