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. |
