… makes a Use Case observation

Take the New York City subway, for example.

The current Use Case says: People need to have a MetroCard before they can go through the turnstile.

Solution: Provide facilities (manned toll booth; automated machines) to purchase (or refill, or add to) a MetroCard.

That’s great. But think about the following situation:

You have a few (or just one) ride left on your MetroCard; you don’t want to miss the next train, so you go in.

But you still need to refill your MetroCard, for next time. Won’t it be great to have an automated ticket machine on the platform? This way, if the train is not there yet, you can leisurly refill your MetroCard, while you’re waiting for the next train, so next time, when you’re in a hurry, you won’t get stuck waiting on line behind 15 people.

p.s. If the train comes right away, you can still do the transaction on the platform of your destination.

What do you think? Is it worth suggeting this to the MTA?

Give me your comments. (You don’t need to be a New Yorker to participate).
