Dear students welcome to gate smashers
In this video i am going to explain
Agile model in Software Engineering
Upto now we have discussed so many models of SDLC.
but from all those models
If anyone asks you latest in interview
or if you are asked anywhere.
Tell me about such a model.
Explain me about such a model.
That is used by the major companies today
Like if you talk about facebook, amazon, google, adobe.
All these companies must be using that.
Tell me such type of model.
Then which model name you will take?
You will take of Agile model.
In the videos all the points of agile model
I will explain you with good example
So that if you are asked in competitive exam, foreign university exam, anywhere.
Then you can easily answer that
So guys like the video fastly
Subscribe the channel
If you have not done till yet
If you have already done.
Then you can subscribe from other devices.
Subscribers are so much important
Come let's start
Firstly what is the meaning of agile?
Agile means move quickly
Here we will not talk about
traditional waterfall model.
Where we say we will start working
on a particular project or model.
For doing that work
We will cross so many phases one by one.
It can took 1 year or 2 year.
When it will complete
After that we will bring it to market.
But if we talk according to today's point of view
Today digital era is moving
If you have any idea, anything in your mind
That if you want to develop there.
If you provided 1.5 years to 2 years
Till then it will obsolate.
It will become old
It is possible already that thing can come in market.
Same thing i will speak here
Agile uses funda of move quickly.
Let me talk with simple real life exmaple
We all the peoples purchase laptop
While purchasing laptop what you see?
I should get latest configuration
We keep the price constraint somewhere.
Configuration wise if we talk about RAM,
Processor, SSD, Hard drive.
We want to get latest technology.
What happens?
We purchased that laptop.
After that we started working on it
After 15-20 days
Latest updated version came from ours that we bought.
What is happening after every 15-20 days?
You can say a latest technology or a
configuration or a updated version comes.
Why this thing is happenig so much fast?
Actual they all are using concept of agile.
What those peoples are doing?
In actual a big project.
See here i am explaining with a very simple diagram.
This is a diagram created by me.
Through this diagram i will explain whole story of agile.
You must remember
If you are studing for your college/university exam.
Then you can pick up that diagram that you are studing in your exams.
Paste all this explanation.
No marks will cut anywhere
In interview you can speak freely
but if you talk about foreign university
Then later they cut the number there.
Messages also comes to us
So there what you can do?
Diagram will be that one
but this will be yours expanation.
So what we are doing in agile?
We are breaking down large, complex project
into small chunks.
Which we say iteration.
Very important point we say it iteration.
So what we are doing?
We are working parallely on iteration.
Suppose there is one iteration
Then we will try to develop that iteration.
As simple we do firstly we will develop.
After that we will test it.
After testing we released that in market
Our particular thing, configuration has arrived in market.
As we released that
After that we will took its feedback.
We will take feedback from customers
In actual what happens?
In nowadays as much as you can see
Feedback is one of the major point.
Any product you purchase
From anywhere you purchase by online media.
Then you will surely check its feedback
So that you can get some decision capability.
Same thing is here
We will collect feedback
Based on feedback
If i need to enhance
If i need to enhance that
I have to adapt that
I have to bring any new thing in that
So by enhancing that
We will re release that.
Same story is of agile.
All these technologies are working in such a way
Not only technical
It is not all about laptop and mobile phone
Even if you go in non tech field,
healthcare field, or you go in aviation field.
Each and every company is now working on agile.
So what those guys are doing there?
This is one concept
By doing big projects in small projects.
By developing iterations parallely
We are trying to bring it in market fastly.
So that my product can come in market within 15-20 days.
As it came i got the feedback
I came to know what are its pros and cons.
On basis of that
I will change that thing in next iteration.
This is the actual funda of this agile.
If we talk about advantages
Then that same came frequent delivery.
Here frequent delivery of product is coming
Most important thing
Here face to face communication with client
It is not like that i will bring my client after two to three phases.
Brother see this is okay or not.
What we guys are doing?
Every week face to face communication with client will happen.
We are going in correct direction or not?
Then changes
If i need changes
It is not like that for changes
I have to wait for 1 month to 2 month.
No i can do frequently changes fastly.
Here capability of changes is large.
Time constraint
Obviously less time will be used here.
Time will be minimum in coming of product.
If we talk about disadvantages
Then less documentation
Agile do not work much on documentation or negotiation.
He says try to implement that thing fastly.
Rather than wasting time on documentation
With client on negotiation
You are wasting so much time on designing.
No we guys by reducing that time
Use it on this thing.
So that my product can come fastly in market.
How you can say maintainence problem
because there is no proper documentation.
One alteration you launched
You provided that to client
That came into market and it is working
In the meantime you did one more new in next two month.
Little bit difficulty can come in maintainence
but the main point of agile is this.
If we want to bring time funda here
Second big thing here is
Here normal architecture is not followed.
A developer, senior developer, manager, senior manager is there.
Here there is no funda of hierarchy.
Here team is very flexible.
There we are providing them freedom to speak.
Bro if you develop on a particular thing
If you are working on a particular thing
Then all are working at a same level.
If we work parallely
Then each and every will give its best.
Every person will try to give its best
because there all are working at a same level.
This is the main story of your agile.
So if you are asked anywhere.
In interview or in foreign university exam.
Then you can mention these things in this.
Thankyou
