We are therefore going to mark this requirement - -5 -00:00:12,650 --> 00:00:15,260 -with an M, for mandatory. It also makes sense to mark as - -6 -00:00:15,260 --> 00:00:18,390 -mandatory the fact that the ATM system checks the PIN of the - -7 -00:00:18,390 --> 00:00:21,480 -card being used by the customer, as that's the typical level of - -8 -00:00:21,480 --> 00:00:23,680 -security that the customer would expect, - -9 -00:00:23,680 --> 00:00:25,760 -therefore we're going to mark as mandatory - -10 -00:00:25,760 --> 00:00:28,320 -also the first requirement here. And of course we - -11 -00:00:28,320 --> 00:00:31,930 -could also perform biometric verification, but based on our knowledge - -12 -00:00:31,930 --> 00:00:33,640 -of the domain, it seems like that should be - -13 -00:00:33,640 --> 00:00:37,410 -an additional verification, rather than the main and only verification - -14 -00:00:37,410 --> 00:00:40,170 -for the system. We will therefore mark it superfluous. - -15 -00:00:40,170 --> 00:00:42,720 -That is something that we can postpone until a later - -16 -00:00:42,720 --> 00:00:45,100 -release, the second requirement. Finally, - -17 -00:00:45,100 --> 00:00:46,740 -another typical operation that customers - -18 -00:00:46,740 --> 00:00:51,070 -perform at ATM machines is depositing. Whereas changing an ATM - -19 -00:00:51,070 --> 00:00:53,850 -card's PIN is not such a common operation. We'll therefore mark - -20 -00:00:53,850 --> 00:00:57,710 -it nice to have this fourth requirement and as superfluous, the - -21 -00:00:57,710 --> 00:01:00,420 -last one. So at the end, what we have is that - -22 -00:01:00,420 --> 00:01:03,540 -we have two mandatory requirements which are the two that we can - -23 -00:01:03,540 --> 00:01:06,280 -satisfy for sure. One, nice to have the requirement, which is - -24 -00:01:06,280 --> 00:01:09,960 -the possible third requirement which we might have time to satisfy. And - -25 -00:01:09,960 --> 00:01:12,980 -the other two that are marked as superfluous, as something that - -26 -00:01:12,980 --> 00:01:16,100 -we might do later, for example in a subsequent release. And of - -27 -00:01:16,100 --> 00:01:19,060 -course there is something subjective in these answers. But - -28 -00:01:19,060 --> 00:01:22,020 -again, based on our knowledge on our understanding of - -29 -00:01:22,020 --> 00:01:23,910 -the domain, these are the one that makes more - -30 -00:01:23,910 --> 00:01:26,640 -sense for an ATM system as we know it. |
