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. -- cgit 1.4.1
