The rational unified - -2 -00:00:03,510 --> 00:00:07,050 -process phases are fundamental aspects of this process and which just touched - -3 -00:00:07,050 --> 00:00:09,200 -on them so we just give a quick overview. And I want to - -4 -00:00:09,200 --> 00:00:12,010 -look at these phases in a little more detail. So, what I'm - -5 -00:00:12,010 --> 00:00:14,960 -going to do is, for each phase, I'm going to discuss what it is, - -6 -00:00:14,960 --> 00:00:18,310 -what it produces and how is the result of the phase suppose - -7 -00:00:18,310 --> 00:00:21,910 -to be,. Assessed, and what are the consequences of this assessment. So - -8 -00:00:21,910 --> 00:00:25,350 -let's start with the first phase, the inception phase. The first phase - -9 -00:00:25,350 --> 00:00:27,920 -goes from the idea of the product to the - -10 -00:00:27,920 --> 00:00:30,990 -vision of the end product. What this involves is basically - -11 -00:00:30,990 --> 00:00:34,230 -to delimiting the project scope. And making the business case - -12 -00:00:34,230 --> 00:00:37,040 -for the product presented. Why is it worth doing? What - -13 -00:00:37,040 --> 00:00:39,870 -are the success criteria? What are the main risks? What - -14 -00:00:39,870 --> 00:00:43,690 -resources will be needed? And so on, specifically these phases - -15 -00:00:43,690 --> 00:00:47,310 -answer three main questions. The first one is, what are - -16 -00:00:47,310 --> 00:00:51,330 -the major users or actors, to use the UML terminology. - -17 -00:00:51,330 --> 00:00:53,450 -And what will the system do for them? To - -18 -00:00:53,450 --> 00:00:56,780 -answer this, these phases produce a simplified use-case model where - -19 -00:00:56,780 --> 00:01:00,480 -only a few use-cases are represented and described. So this - -20 -00:01:00,480 --> 00:01:03,390 -is a sort of initial use-case model. The second question - -21 -00:01:03,390 --> 00:01:05,610 -is about the architecture, what could be an architecture - -22 -00:01:05,610 --> 00:01:08,370 -for the system? So in this phase we will normally - -23 -00:01:08,370 --> 00:01:12,420 -also develop a tentative architecture. So an initial architecture that - -24 -00:01:12,420 --> 00:01:16,540 -describes the most crucial subsystems. Finally this phase also answers - -25 -00:01:16,540 --> 00:01:18,890 -the question, what is the plan and how much - -26 -00:01:18,890 --> 00:01:21,620 -will it cost? To answer this question. This phase will - -27 -00:01:21,620 --> 00:01:24,930 -identify the main risks for the project and also produce - -28 -00:01:24,930 --> 00:01:28,600 -a rough plan with estimates for resources, initial planning for - -29 -00:01:28,600 --> 00:01:32,820 -the phases and dates and milestones. Specifically, the inception phase - -30 -00:01:32,820 --> 00:01:36,370 -generates several deliverables. It is very important that you pay - -31 -00:01:36,370 --> 00:01:39,600 -attention so that you understand what this deliberate approach are. - -32 -00:01:39,600 --> 00:01:42,320 -Starting from the first one, which is the vision document. - -33 -00:01:42,320 --> 00:01:44,800 -And this is a document that provides a general - -34 -00:01:44,800 --> 00:01:48,420 -vision of the core projects requirements, key features and main - -35 -00:01:48,420 --> 00:01:51,890 -constraints. Together with this, the inception phase also produces an - -36 -00:01:51,890 --> 00:01:54,900 -initial use case model, as I just mentioned. So this - -37 -00:01:54,900 --> 00:01:57,720 -is a use case model that includes an initial set - -38 -00:01:57,720 --> 00:02:00,670 -of use cases, and then will be later refined. Two - -39 -00:02:00,670 --> 00:02:04,300 -additional variables are the initial project glossary, which describes the - -40 -00:02:04,300 --> 00:02:07,330 -main terms, using the project and their meaning, and the - -41 -00:02:07,330 --> 00:02:10,229 -initial business case which includes business context. And - -42 -00:02:10,229 --> 00:02:13,470 -success criteria. Yet another deliverable for the inception phase - -43 -00:02:13,470 --> 00:02:15,770 -is the initial project plan, which shows the - -44 -00:02:15,770 --> 00:02:20,650 -phases, iterations, roles of the participants, schedule and initial - -45 -00:02:20,650 --> 00:02:23,610 -estimates. In addition, the inception phase also produces - -46 -00:02:23,610 --> 00:02:26,810 -a risk assessment document, which describes the main risks - -47 -00:02:26,810 --> 00:02:29,970 -and counters measures for this risk. Finally, and this - -48 -00:02:29,970 --> 00:02:32,430 -is an optional deliverable, in the sense that it, - -49 -00:02:32,430 --> 00:02:34,990 -it might or might not be produced, depending on the specific - -50 -00:02:34,990 --> 00:02:37,870 -project. As part of the inception phase we might also generate - -51 -00:02:37,870 --> 00:02:41,780 -1 or more prototypes. For example, we might develop prototypes to - -52 -00:02:41,780 --> 00:02:45,590 -address some specific risks that we have identified or to show some - -53 -00:02:45,590 --> 00:02:48,380 -specific aspect of the system of which we are unsure to - -54 -00:02:48,380 --> 00:02:51,910 -the stakeholders. So basically all the typical users of prototypes that - -55 -00:02:51,910 --> 00:02:54,600 -we discussed before. So when we're done with the inception phase - -56 -00:02:54,600 --> 00:02:58,300 -we hit the first milestone for the cycle we are currently performing. - -57 -00:02:58,300 --> 00:03:00,600 -And so there are some evaluation criteria that will tell - -58 -00:03:00,600 --> 00:03:03,640 -us whether we can consider the inception phase concluded or not. - -59 -00:03:03,640 --> 00:03:06,840 -And the first of this criteria is stakeholder concurrence, which - -60 -00:03:06,840 --> 00:03:10,510 -means that all the stakeholders must agree on the scope, definition, - -61 -00:03:10,510 --> 00:03:13,510 -and cost schedule estimates for the projects. The second criteria - -62 -00:03:13,510 --> 00:03:17,040 -needs requirements understanding, out of the initial primary use cases that - -63 -00:03:17,040 --> 00:03:20,380 -we have identified so far, the right one for our system. - -64 -00:03:20,380 --> 00:03:23,760 -And other criteria is the credibility of the cost schedule estimates, - -65 -00:03:23,760 --> 00:03:28,280 -the priorities, defined the risks identifies and the countermeasures for - -66 -00:03:28,280 --> 00:03:31,590 -those risks, and the development process that we're following. Finally, in - -67 -00:03:31,590 --> 00:03:34,000 -the case we produce prototypes as part of the inceptional - -68 -00:03:34,000 --> 00:03:37,520 -phase, this will also be evaluated and assessed to judge the - -69 -00:03:37,520 --> 00:03:39,960 -overall outcome of the phase. So what happens if the - -70 -00:03:39,960 --> 00:03:43,170 -project fails to pass this milestone? So if the outcome of - -71 -00:03:43,170 --> 00:03:46,020 -the inception phase is considered to be inadequate with respect - -72 -00:03:46,020 --> 00:03:48,642 -to one or more of these criteria. Well at this point, - -73 -00:03:48,642 --> 00:03:51,240 -since we're kind of an initial phase of the cycle - -74 -00:03:51,240 --> 00:03:54,370 -the project may be cancelled or considerably re-thought. So to - -75 -00:03:54,370 --> 00:03:57,610 -summarize all of these in one sentence the Inception Phase - -76 -00:03:57,610 --> 00:04:00,320 -is the phase in which we produce. Then you shall vision, - -77 -00:04:00,320 --> 00:04:04,750 -used case model, project plan, risk assessment and possibly, prototypes - -78 -00:04:04,750 --> 00:04:07,290 -for the project. And we have to make sure, that - -79 -00:04:07,290 --> 00:04:10,680 -all of this deliverables satisfy a set of criteria, so - -80 -00:04:10,680 --> 00:04:13,770 -that we can continue on the project. And otherwise, we'll either - -81 -00:04:13,770 --> 00:04:17,160 -cancel the project or rethink its scope, or other aspects of it. |
