The fact that it is used + +3 +00:00:05,800 --> 00:00:08,810 +case driven and the fact that it is architecture centric. + +4 +00:00:08,810 --> 00:00:11,950 +The third and final distinguished aspect of R.U.P. is that + +5 +00:00:11,950 --> 00:00:15,210 +it is iterative and incremental. So let's see what that + +6 +00:00:15,210 --> 00:00:18,870 +means by considering the lifetime of a software project. Basically, + +7 +00:00:18,870 --> 00:00:22,120 +the lifetime of a rational unified process consists of a + +8 +00:00:22,120 --> 00:00:24,920 +series of cycles, such as the ones that are represented here. + +9 +00:00:24,920 --> 00:00:28,070 +Cycle one, cycle two, through cycle n. And as + +10 +00:00:28,070 --> 00:00:30,990 +you can see, these cycles can also be called increments. + +11 +00:00:30,990 --> 00:00:33,280 +And each one of the cycles involves all of + +12 +00:00:33,280 --> 00:00:36,700 +the main phases of software development. In addition, each cycle + +13 +00:00:36,700 --> 00:00:39,700 +results in a product release which can be internal + +14 +00:00:39,700 --> 00:00:43,210 +or external. More precisely, each cycle terminates with a product + +15 +00:00:43,210 --> 00:00:46,340 +release that includes a complete set of artifacts for + +16 +00:00:46,340 --> 00:00:50,150 +the project. That means code, manuals, use cases, non-functional + +17 +00:00:50,150 --> 00:00:52,840 +specification, test cases, and so on. So, I've just + +18 +00:00:52,840 --> 00:00:55,760 +said, that each cycle involves all of the main phases + +19 +00:00:55,760 --> 00:00:59,440 +of software development. Specifically, each cycle is further divided + +20 +00:00:59,440 --> 00:01:04,040 +in four phases. Inception, elaboration, construction and transition. In a + +21 +00:01:04,040 --> 00:01:06,290 +minute, we will look at each one of these + +22 +00:01:06,290 --> 00:01:08,840 +phases in detail and see how they relate to the + +23 +00:01:08,840 --> 00:01:12,150 +traditional activities of software development. Before that, I want + +24 +00:01:12,150 --> 00:01:15,760 +to mention the last level of these iterations, which happens + +25 +00:01:15,760 --> 00:01:20,330 +within these individual phases More precisely, inside each of these + +26 +00:01:20,330 --> 00:01:24,230 +phases, there might be multiple iterations. So what are these + +27 +00:01:24,230 --> 00:01:28,070 +iterations? Well, basically, each iteration corresponds to a group of + +28 +00:01:28,070 --> 00:01:30,550 +use cases that are selected so as to deal with + +29 +00:01:30,550 --> 00:01:33,200 +the most important risks first. So if you have a + +30 +00:01:33,200 --> 00:01:35,510 +set of use cases that you're considering, which means that + +31 +00:01:35,510 --> 00:01:37,450 +you have a set of features that you need to + +32 +00:01:37,450 --> 00:01:41,260 +implement, you will select for each iteration the most risky + +33 +00:01:41,260 --> 00:01:44,720 +ones that you still haven't realized, and realize them in that + +34 +00:01:44,720 --> 00:01:47,720 +iteration. And then continue in the following iterations with less and + +35 +00:01:47,720 --> 00:01:50,980 +less risky ones. So basically what happens in the end is + +36 +00:01:50,980 --> 00:01:52,960 +that essentially each iteration extends + +37 +00:01:52,960 --> 00:01:55,220 +the functionality beyond the previous iteration. -- cgit 1.4.1
