Congratulations, will aren't the two fundamental approaches we learned about the traditional or what's cool I can bridge and another country learn to bounce edge approach, which is actually related to the scrum because Scrum is a subset of JIRA. So now, if you have understanding on both approaches, now let's make a short summary on each approach. So in first traditional approach, traditional approaches sequential model is reliable model. But the main things that we need to consider when we use this approach, is it Hello the full force and a lot of times we'll need to spend on the entire play around for example, in situation one, project development day, a little, let's say, two years or one year when it's a relatively weak time lengths. Now, once you actually reach the destination, when the actual Reasonable point and when project is done, it could have been that many features many force were spent for nothing useless.

Because, for example, when you reach some point you realize it's actually you spend a lot of force to develop some particular features or whatever, as in our example was found a local force on second floor which was useless. And that's actually the point that needs to be considered before you're sticking to the traditional model. In other kind of a gel is not so sequential, it's actually approach when all process groups are interact. From some point it's not so relatable, it's also a point. But the main purpose here is that we do a durational blank so we blend small piece of deliverable we reach this destination reaches buoyant, when Elyse, whether we are doing the right direction? And if yes, we go to the next step and if no, we make some adjustment and then decrease demands and go to the next.

So this kind of approach is pretty popular because you're flexible you're which actually could respond to the change query very quickly. And it's very valuable, I think, on that approach. So that was, once again, short comparison or journalism both approaches. Let's start learning Scrum now and seeing the next lessons.
