Hugill, let's talk about these approach. So as you see here, we have brought to the groups as we've seen, similar to what we've seen in the previous lesson regarding waterfall, a traditional approach, but now we see that process groups are aligned in parallel, and they are under for one group with another. So there is no sequential or Anza. Absolutely true for is that a jail because you're in one iteration. All process groups are interact. And now let's imagine the situation similar to what we have done on the lessons related to the traditional approach.
My dear students, you will be as a customer and let's imagine that you would like to build your house, a house of your dreams. And this time, we are going to stick to my general approach. So the first thing that you would like to build is a whole automation system. Why Hold because you're absolutely confident that hole is something that you really want. And you are absolutely confident about the ways the hole should be built. So you create your plan for a call for a limited piece of deliverable.
And you're present your request as engineers, okay? And in a couple of days, let's say, zero turn back to you and say, hey, we've done the quote, and we examine the deliverable, and you examine the scroll according to your request. It looks very nice, because that's exactly what you want. So now you're ready to go to the next piece. And the next piece is going to be holding in the room and pitching. So you agreed and you plan for living room and kitchen now.
And once again, you pass your plan to the engineers, and in a couple of days after they return back to you and say to you, hey, we've done the living room and kitchen please eminent and you're checking it out, Gordon, do you It looks really nice. So are you are you really enjoy about living room and kitchen about the whole, but you start to realize at this point of time that it's not enough brightness in the interior. So you may want to install more windows. And you realized it. And you asked his engineers Hey guys, please add more windows. And they accepted your request for more Windows as we see here and edit more windows to you.
So you're checking it again in a couple of days later, and similar windows and now you're absolutely satisfied on what you see actually. You're happy about this, but still it's not completed yet. So the next step is a grass entries. You want your house to be beautiful and nice sexually. So your best and your requests for two engineers and they can plant trees and grass for you. So It looks nice now.
And it is a call. So if you're rude, isn't it? Well, you're not sure exactly now, but we've done it in iteration all the way from one step to the next step to the next step when you was not completely satisfied, we ask them to redo it a little bit to adjust something to add more windows. And in this step by step manner, we reached the final point. And this final point is exactly what you wanted. So you are thinking about this and you realize that yes, this time, it's much more close to what you exactly wanted because you don't have this useless second floor, which was developed according to the waterfall plan, or traditional approach.
And but instead you have a big hole which really nice and makes more sense for you. So this time, you're already happy about the results received. Want to quick note here, of course. The way we created this house is not the the ways that house should be built. As long as you are engineer or have relations to the building of apartments, houses, you can say to me that Alex, it's a totally wrong approach to build a house. And I absolutely agree with you.
You can punish me and employment. But my main goal here was to explain user iteration process. So when we go from one step to another steps, or from one piece of deliverable to another piece of deliverable, and we go until we completely satisfied and then the main idea or philosophy was agile approach. So once again, my main goal was to explain us philosophy, but not the way how to build a house. And finally, let's make a summer. And Jeff, jealous, flexible approach where all the process groups are indirect in Perl.
That's absolutely true. So we didn't want a piece of deliverable. So we didn't want a piece of deliverable all process groups are in direct and that's true. The next point is that a gel is about a limited blend. And that's also true. We haven't made a blend for the entire house or entire project we did blend for won't be so deliverable festivals.
This was a whole exam, living room and kitchen. And then we installed Windows. And then finally we blunt, Teresa aggress. So gel is about limited planning. And in that way you can reach your target much more closer or better. And finally, agile is about close collaboration with the customers.
And that's also true, because when you were not completely satisfied on the whole, you ask it engineers to add more windows and they did it because you examine each deliverable and you provide them with a feedback if I'm okay with what was delivered or not. So cooperation Between gossamer around engineers or someone who actually execute the project, it's much more closer than the traditional or waterfall approach. So I was that was a story about the gel. Now we have basic understanding on both approaches on traditional and the gel, and we can move forward
