And to introduce XP, I'm going to start with - -4 -00:00:08,430 --> 00:00:12,520 -a quote. The quote says XP is a lightweight methodology for - -5 -00:00:12,520 --> 00:00:16,180 -small to medium sized teams developing software in the face - -6 -00:00:16,180 --> 00:00:19,770 -of vague or rapidly-changing requirements. And this is a quote from - -7 -00:00:19,770 --> 00:00:23,010 -Kent Beck the American Software Engineer that created extreme programming. - -8 -00:00:23,010 --> 00:00:25,630 -And by the way Beck was one of the original 17 - -9 -00:00:25,630 --> 00:00:29,570 -developers who signed the manifesto in 2001. And as you can see - -10 -00:00:29,570 --> 00:00:31,940 -we are still talking about the methodology. So we are not just - -11 -00:00:31,940 --> 00:00:35,760 -talking about going out and just start writing software. There are principles. - -12 -00:00:35,760 --> 00:00:38,130 -And there are practices that we need to follow, but we're going - -13 -00:00:38,130 --> 00:00:40,330 -to do it in a much more agile, and a much more - -14 -00:00:40,330 --> 00:00:43,720 -flexible ways than we did for our software processes. And also note - -15 -00:00:43,720 --> 00:00:45,340 -that the vague and rapidly changing - -16 -00:00:45,340 --> 00:00:47,190 -requirements are explicitly mentioned, because this - -17 -00:00:47,190 --> 00:00:51,130 -is really one of the important parts about all of this agile methodologies. - -18 -00:00:51,130 --> 00:00:54,780 -so what is XP? XP is a. Lightweight. Humanistic. - -19 -00:00:54,780 --> 00:00:58,250 -Discipline. Of software development. It is lightweight because it doesn't - -20 -00:00:58,250 --> 00:01:02,190 -overburden the developers with an invasive process. So process - -21 -00:01:02,190 --> 00:01:04,510 -is kept to a minimum. It's humanistic because as we - -22 -00:01:04,510 --> 00:01:07,760 -said, it's centered on people. People, developers, customers, are - -23 -00:01:07,760 --> 00:01:10,520 -at the center of the process. It's a discipline, as - -24 -00:01:10,520 --> 00:01:12,870 -we said, it includes practices that we to Follow. - -25 -00:01:12,870 --> 00:01:16,470 -And finally, is of course about software development. Software development - -26 -00:01:16,470 --> 00:01:19,530 -is a key point of the whole method. In XP, developing - -27 -00:01:19,530 --> 00:01:22,910 -is like driving, imagine having a road, a wind road, we need - -28 -00:01:22,910 --> 00:01:25,110 -to able to drive our car down the road, take the - -29 -00:01:25,110 --> 00:01:29,640 -abrupt turns, react promptly to changes, for example obstacles on the road. - -30 -00:01:29,640 --> 00:01:32,610 -So, in a nutshell, change is the only constant. Eyes always - -31 -00:01:32,610 --> 00:01:34,980 -have to be on the road and it's about steering and not - -32 -00:01:34,980 --> 00:01:38,110 -pointing, and XP is trying to do the same thing, while creating - -33 -00:01:38,110 --> 00:01:42,190 -softer systems. In XP we need to adopt a mentality of sufficiency, - -34 -00:01:42,190 --> 00:01:44,820 -what does that mean? How would you program if you had all - -35 -00:01:44,820 --> 00:01:48,010 -the time in the world? No time constraints at all, you will probably - -36 -00:01:48,010 --> 00:01:51,090 -write tests instead of skipping them, because there's no more resources. You - -37 -00:01:51,090 --> 00:01:53,200 -will probably restructure your code often, - -38 -00:01:53,200 --> 00:01:55,210 -because you see opportunities to improve it, - -39 -00:01:55,210 --> 00:01:57,300 -and you will take them. And you will probably talk to fellow - -40 -00:01:57,300 --> 00:02:00,910 -programmers and with the customer, interact with them, and this is actually the - -41 -00:02:00,910 --> 00:02:04,700 -kind of mentality that XP is trying to promote and agile processes - -42 -00:02:04,700 --> 00:02:07,760 -in general. And we will see that the following some of the practices - -43 -00:02:07,760 --> 00:02:11,250 -that XP is advocating, you can actually achieve these goals and you can - -44 -00:02:11,250 --> 00:02:12,840 -actually behave in this way. And the - -45 -00:02:12,840 --> 00:02:15,010 -development process is going to benefit overall. |
