1
00:00:00,230 --> 00:00:02,590
To make this a little more concrete, let's look at

2
00:00:02,590 --> 00:00:07,466
an example involving cycles, phases, and iterations. Let's assume that we

3
00:00:07,466 --> 00:00:10,250
have to develop a banking IT system. The first possible

4
00:00:10,250 --> 00:00:12,730
cycle for such a system could be one in which we

5
00:00:12,730 --> 00:00:16,280
implement the basic withdrawal facilities. What this means is that,

6
00:00:16,280 --> 00:00:18,400
at the end of this cycle, there will be the release

7
00:00:18,400 --> 00:00:22,130
of the product that implements this piece of functionality. But notice

8
00:00:22,130 --> 00:00:25,500
that this will not be the only product release because within

9
00:00:25,500 --> 00:00:28,580
the cycle, we will perform also the four phases that

10
00:00:28,580 --> 00:00:31,020
we mentioned before, inception, elaboration,

11
00:00:31,020 --> 00:00:33,550
construction, and transition. And within each

12
00:00:33,550 --> 00:00:36,980
of these phases, we might have multiple iterations. And at the

13
00:00:36,980 --> 00:00:39,710
end of each iteration, we will also have a product release.

14
00:00:39,710 --> 00:00:41,790
Which in this case, will be an internal one. As

15
00:00:41,790 --> 00:00:44,690
you can see, the iterative nature is really inherent in the

16
00:00:44,690 --> 00:00:48,030
unified rational process. So, now let's clean up here, and let's

17
00:00:48,030 --> 00:00:50,814
see what some other possible cycles could be for our banking

18
00:00:50,814 --> 00:00:54,070
IT system. Here, I'm showing two possible additional ones. The first

19
00:00:54,070 --> 00:00:57,800
one, cycle two, which will develop the account and system management. And

20
00:00:57,800 --> 00:01:00,230
the third one, cycle three, which will develop the full account

21
00:01:00,230 --> 00:01:04,620
management and cross selling. Similarly to cycle one, also these cycles will

22
00:01:04,620 --> 00:01:07,570
produce a product, both at the end of the cycle, and

23
00:01:07,570 --> 00:01:10,740
within the cycle in the different phases. And there's a few more

24
00:01:10,740 --> 00:01:13,150
things to note. So the first one, is that each cycle

25
00:01:13,150 --> 00:01:15,900
focuses on a different part of the system. So what you will

26
00:01:15,900 --> 00:01:19,350
do, when you use the rational unified process, you will select a

27
00:01:19,350 --> 00:01:23,320
subset of use cases that you want to realize within your cycle.

28
00:01:23,320 --> 00:01:26,640
And the final product for that cycle, will be a product that

29
00:01:26,640 --> 00:01:30,190
realizes those use cases. This is the first aspect. The second one,

30
00:01:30,190 --> 00:01:33,290
is that these cycles, as you can see, are slightly overlapping. So

31
00:01:33,290 --> 00:01:35,880
it is not the case that you finish a cycle, and then

32
00:01:35,880 --> 00:01:37,580
you start the next one. So there is a little bit of

33
00:01:37,580 --> 00:01:41,250
overlap among cycles, and we'll talk about that more. And finally,

34
00:01:41,250 --> 00:01:43,600
I want to stress one more that each cycle

35
00:01:43,600 --> 00:01:46,960
contains four phases, and each one of these phases might

36
00:01:46,960 --> 00:01:49,890
be further splayed in iterations. So that's kind of a

37
00:01:49,890 --> 00:01:52,610
high level view of how the whole process will work.
