0 00:00:08,240 --> 00:00:13,280 After watching this video, you'll be able to distinguish between Agile and Scrum, define the 1 00:00:13,280 --> 00:00:17,680 key characteristics of the Scrum methodology, and describe the steps in the Scrum process. 2 00:00:19,360 --> 00:00:25,360 Agile and Scrum are two words that many people use interchangeably, but there really is a difference. 3 00:00:26,000 --> 00:00:32,640 Agile is a philosophy. It is not perscriptive. It's a philosophy for doing work. Scrum 4 00:00:32,640 --> 00:00:39,840 is a methodology. It is perscriptive. It's a methodology for working in an agile fashion. So, 5 00:00:39,840 --> 00:00:45,360 what is Scrum? Well, it's a management framework for doing incremental product development. 6 00:00:46,000 --> 00:00:52,880 It emphasizes small, cross-functional, self managing teams. And it provides a structure of 7 00:00:52,880 --> 00:01:00,000 roles and rules, and artifacts, and we're going to learn about all of those. It also uses these fixed 8 00:01:00,000 --> 00:01:05,680 length increments that are called sprints. We're going to get into sprints in a moment. And it has 9 00:01:05,680 --> 00:01:13,040 a goal of building an increment each time through a sprint, a potentially shippable increment each 10 00:01:13,040 --> 00:01:18,800 time through that iteration. Very, very important that you get stuff in your customers' hands early. 11 00:01:20,400 --> 00:01:28,080 So, I like to say, "Easy to understand, difficult to master." There's not a lot of rules in Scrum, 12 00:01:28,080 --> 00:01:33,440 but somehow it's really, really hard to do. And I attribute it to being a ballerina, like, 13 00:01:33,440 --> 00:01:38,720 all you have to do is dance on your toes, right? How hard could it be? Well, we all know 14 00:01:38,720 --> 00:01:45,760 it takes years to gain the muscle memory and build up your muscles to be able to dance on your toes. 15 00:01:45,760 --> 00:01:52,800 It's not as easy as it looks, and Scrum is the same way. Not as easy as it looks. So, my advice 16 00:01:52,800 --> 00:01:58,240 is if you've never done it before, hire somebody on the team who has, have someone to guide you, 17 00:01:58,240 --> 00:02:05,600 someone to mentor you, because it is a lot harder than it looks. So, let's talk about the sprint. A 18 00:02:05,600 --> 00:02:12,080 sprint is one iteration through the design, code, test, deploy cycle, right? So, you're doing these 19 00:02:12,080 --> 00:02:17,280 mini iterations. It's kind of like the software delivery lifecycle. In a mini inner iteration. 20 00:02:18,720 --> 00:02:22,560 Every sprint should have a goal, right? You should, everybody should, understand what is 21 00:02:22,560 --> 00:02:27,600 it we're trying to build with this increment. What should this increment do at the end of the sprint? 22 00:02:28,160 --> 00:02:32,000 And then the Sprints are usually two weeks long, some people say two to four weeks, 23 00:02:32,560 --> 00:02:37,920 I find four weeks to be far too long. A lot of things can change in four weeks, right? Remember 24 00:02:37,920 --> 00:02:42,240 small, want to work in small batches. And so, I think it's really important to try to keep your 25 00:02:42,240 --> 00:02:46,960 sprints to two weeks, some people get them down to one. That's a little too fast for me, but two weeks 26 00:02:46,960 --> 00:02:53,440 seems to be a good goal to make your sprints. So, let's look at the steps in the scrum process. 27 00:02:54,080 --> 00:02:58,240 You've got the product backlog. This is the list of all the stories 28 00:02:58,240 --> 00:03:02,160 of everything you ever want to do with your product. This is it, this is everything, 29 00:03:02,160 --> 00:03:08,000 it's kind of your to-do list of everything you might want to do. Then we've got something called 30 00:03:08,000 --> 00:03:12,640 backlog refinement, that's when we go through the product backlog. And we groom the stories to 31 00:03:12,640 --> 00:03:16,400 make sure that they're sprint ready because we want to start doing planning on those stories. 32 00:03:17,280 --> 00:03:23,760 Then, we have a planning meeting where we produce a sprint backlog. Notice the sprint backlog is 33 00:03:23,760 --> 00:03:29,200 smaller than the product backlog. The sprint backlog is just those stories that we want to 34 00:03:29,200 --> 00:03:34,480 accomplish in the next sprint, in the next two weeks. So we take from that product backlog, 35 00:03:35,040 --> 00:03:40,720 pare it down into a sprint backlog of just the stories to execute in the next sprint. And then 36 00:03:40,720 --> 00:03:46,800 we start our two week sprints. And every day we get together and do the daily Scrum or the daily 37 00:03:46,800 --> 00:03:51,520 stand-up where everybody gets to answer three questions. What did you do yesterday? What are 38 00:03:51,520 --> 00:03:55,440 you going to do today? And is there anything blocking you or impeding you from getting up 39 00:03:55,440 --> 00:04:00,080 further? So you go through that every day for two weeks, build your sprint. 40 00:04:00,080 --> 00:04:05,840 And then finally, hopefully, you've got a valuable shippable increment at the end of that process. 41 00:04:07,120 --> 00:04:11,600 Agile development is iterative. You're going to go through this again and again. 42 00:04:11,600 --> 00:04:17,760 Design, code, test, deploy, design, code, test, deploy. I mean, this is this is what you do 43 00:04:17,760 --> 00:04:22,720 in every sprint. And notice, you know, you've got to have some kind of deploy, it's not enough 44 00:04:22,720 --> 00:04:27,440 to just do design, code, and test, design, code without deploying it and getting feedback, 45 00:04:27,440 --> 00:04:32,560 right? So, so every sprint you make a plan, you go through the software delivery lifecycle 46 00:04:33,200 --> 00:04:38,080 cycle, and then you deploy that application and you get some feedback from the customer 47 00:04:38,080 --> 00:04:45,840 that is input to the next plan to go through the next cycle. In this video, you learn that Scrum is 48 00:04:45,840 --> 00:04:51,360 a methodology that follows the Agile philosophy. The Scrum management framework provides structure 49 00:04:51,360 --> 00:04:57,760 through defined roles, meetings, rules and artifacts. It also prescribes small 50 00:04:57,760 --> 00:05:03,680 cross-functional, self-organizing teams. Uses fixed length iterations called sprints, 51 00:05:03,680 --> 00:05:09,840 and produces a potentially shippable product increment with every iteration.
