Abstract:

Your requirements document needs to focus on the user’s goals. They should not be marketing’s list of features 'we’ve got to have' because the competition has these features. They should not be a list of things the programmers think ought to be included 'because we can add those things for very little cost.' Feature bloat does not benefit the user.
