There - -4 -00:00:08,820 --> 00:00:12,350 -is no good project without good communication. And XP tries to - -5 -00:00:12,350 --> 00:00:15,470 -keep the right communication flowing and it uses several practices - -6 -00:00:15,470 --> 00:00:18,890 -to do that. It's got practices based on and require information - -7 -00:00:18,890 --> 00:00:21,950 -and in general share the information. For example, pair programming. - -8 -00:00:21,950 --> 00:00:25,140 -And we're going to say more about that. User stories, customer involvement, - -9 -00:00:25,140 --> 00:00:28,240 -all activities that help communication, - -10 -00:00:28,240 --> 00:00:30,440 -that faster communication. Another important - -11 -00:00:30,440 --> 00:00:33,420 -principle that we already saw, is simplicity. And the motto here - -12 -00:00:33,420 --> 00:00:35,680 -is live for today without worrying too much about the - -13 -00:00:35,680 --> 00:00:38,230 -future. When you have to do something, look for the simplest - -14 -00:00:38,230 --> 00:00:40,580 -thing that works. And the emphasis here is on, that - -15 -00:00:40,580 --> 00:00:43,520 -works. We want to build something simple, but not something stupid. - -16 -00:00:43,520 --> 00:00:47,090 -Feedback. That's extremely important in XP, and it occurs at - -17 -00:00:47,090 --> 00:00:50,560 -different levels, and it is used to drive changes. For example, - -18 -00:00:50,560 --> 00:00:53,910 -developers write test cases. And that's immediate feedback. If your test cases - -19 -00:00:53,910 --> 00:00:56,140 -fail, there's something wrong with the code. Or there's something that you - -20 -00:00:56,140 --> 00:00:59,690 -still haven't developed. Developers also estimate new stories right away as soon - -21 -00:00:59,690 --> 00:01:02,060 -as they get them from the customers and that's immediate feedback to - -22 -00:01:02,060 --> 00:01:05,515 -the customer. And finally, on a slightly longer time frame, customers and - -23 -00:01:05,515 --> 00:01:07,820 -tester develop together functional system test - -24 -00:01:07,820 --> 00:01:09,600 -cases to assess the overall system. - -25 -00:01:09,600 --> 00:01:12,100 -And also in this case, that's a great way to provide feedback - -26 -00:01:12,100 --> 00:01:15,850 -and by the way, also to help communication. And finally, courage, the courage - -27 -00:01:15,850 --> 00:01:18,860 -to throw away code if it doesn't work. To change it if you - -28 -00:01:18,860 --> 00:01:21,710 -find a way to improve it. To fix it if you find a problem. - -29 -00:01:21,710 --> 00:01:24,300 -To try out new things if you think that they might work better - -30 -00:01:24,300 --> 00:01:27,410 -than what you have right now. Now, that we can build and test systems - -31 -00:01:27,410 --> 00:01:30,150 -very quickly, we can be much braver than what we were before. So - -32 -00:01:30,150 --> 00:01:33,790 -how do we accomplish all that? And what are XP's practices that are going to - -33 -00:01:33,790 --> 00:01:37,750 -help us follow these principles and adhere to those values? These are some - -34 -00:01:37,750 --> 00:01:40,900 -of XP practices. There are more, but those are the ones that I'd like - -35 -00:01:40,900 --> 00:01:44,240 -to discuss in a little more depth, individually. Incremental planning, - -36 -00:01:44,240 --> 00:01:48,230 -small releases, simple design, test first, refactoring. We will actually - -37 -00:01:48,230 --> 00:01:51,680 -have a whole lesson next on refactoring. Pair programming, continuous - -38 -00:01:51,680 --> 00:01:55,240 -integration, and on-site customer. So let's start with incremental planning. |
