When Requirements Collide

[article]

I could have calculated how much money to spend to buy just enough time, but not everyone wears a calculator watch.

I'm not big on conspiracy theories, and I'm not accusing anyone of devilish design here. But is it possible that designing the kiosk's user interface not to show the amount of parking time requested was a conscious decision? I'm going to watch out for this kind of disconnect the next time I drill down from business requirements into the detailed requirements that are intended to achieve the business objectives.
