Software Development Life cycle

hi guys welcome you ordered another video of software testing by M K T so in this video we're gonna talk about software development lifecycle before we start with this video make sure that you are subscribed to my channel let's get started so in this video we are going to talk about what do you mean by software development lifecycle C as the name suggests software development life cycle whenever software any company is developing what are stages is it goes through that is part of software maintenance second actual definition says that software development lifecycle it is a step-by-step procedure or a standard procedure to develop any new software is called a socket like sector now why company should follow SDLC software development lifecycle or what would happen if they don't follow SDLC if company don't follow SDLC they will not come to know what is the requirement first of all they will not get to know how much money to invest in it they will not get to know what will be the profit or loss at the end of the at the end and they will not get to know how many ingenious they need to involve in making their software so for that purpose company always follow software development life cycle so if we talked about the stages we have in software development life cycle the stages we have are listen the early guys the first stage is college requirement collection first stage is chorus requirement connection that means there are the question arises who do the requirement touch requirement collection is done by product analyst product analyst is the person who will be in the product based companies and business analyst is the person who will do the requirement collection in the service response I'm going to take an example of so this okay so be a business analyst he will go to the customer piece he will correct the requirement in the business language he will come back to the company convert everything he has understood in the business language to technical things and he gonna explain it to the technical team technical team consisting of architects developers product head that is product managers and QE q ingenious this was the first step the second stage of SDLC is called as easy beauty study now physically this study is nothing but in this stage they define rather to take up the project if they are going to take up the project are they going to get any profit or not so this is the stage where they decide whether you take up the project or not this stage consisting of different themes the first the first one the first person is called as product head or product manager the second is finance team HRT architects and business I just these are the people who decide whether to take up the project or not they may talk about three things whether they have enough resources to take off the project when I talked about the resources I mean whether they have proper engineers developers NQ it to take up the project or not do the second is do they have proper lab setups or not do they have proper lab setups about I mean if the big of the project lab setups required are they having it and the third is which are they having the technology to take up the project or not so the designer on the screen mainly thinks decide whether to take up the project or not now I'm going to talk about the role of product manager he is the person who will take the data from business analyst arcattack finished him and a charting and he is the person who will decide whether to take of the project ah ba ba is a person who will correct the requirement as I have already said his role is to correct the requirement he is going to requirement and architect is a person who will think from the technical point of view that means which technology to follow to take up the project finance team they were thing from the money point of view if they are going to take the project are they going to get any profit or not if the English dismiss or money are they going to return anything are they going to get properly so an attractive actually more technical teams of people who've written that they've got this many ingenious in the product so it is the job of the exciting to hire those people he will collect product hand that is product product manager he will take the data from everyone and he will segment who think of the project or not I have explained in a very easy language third third stage of software development lifecycle is called as design design is in design we have two things one is high level design other one is low level design high level design is a design the architecture of the application how the application you will look like that is for high level design if I talk about the lower level design how each and every models will look like that is called as low level design so I hope I mean if I'm going to give you the example imagine understand give me a very better way let us take example that I have come I have bought a site have bought a site now I have decided that I am going to construct in that I am going to construct one room one hall one kitchen to wash poops one lawn one parking area this is - I mean I these are things I'm gonna make in my site which I have bought that is for this high level design now what is low level design suppose my site is like this this is the increase I will be having a forum here with that attached motion will be that with that attached living room should be there with that attached kitchen should be there here launched should be that help button should be that talking everything in detail is called as low level design I'm gonna give you one more example let's talk about Watson what's up is having an option corners select a contact a send a message they also have the option of attachment that is what is I design I'm going to talk about low level design if I click on attachment it is having multiple options in it let us say we having an option of selecting an image video document.location files they have multiple option to select so that is furnished the only reason I'm talking in depth that talking if if I'm talking about any software that is talking about the Gmail Gmail is having an option of composing a me sent me outbox spam logout learning that is for his high level ISM now what is new level using do a compose meant it will be having an option contest to to human scent so that will remind me lightly BC BC subject body attachment send button cancel button signature that is for a strong liberal different I hope it is very understandable right so once the design phase is completed the for stage in software development lifecycle say that coding coding has to be done developer will start writing the code while seeing the lower level design and quite and I always remember business analyst he is the bridge between the customer and the developers so once after the coding is done the first stage of software development life cycle is harnessed testing which we will be doing it once the testing is done software is working perfectly fine we are going to reuse it that comes a six-page the sixth stage is called as installation and implementation our sighting genius site ingenious fielding genius they will go to the customers place install the software make it ready so that customer can start their running that business with the help of the software that is forest installation installation or implementation yeah coming to the seventh street that is called as maintenance is the last page of software development life cycle is called as maintenance fees maintenance is mainly done by developer and QA now I'm going to tell you what do you mean the maintenance phase once we have given a Stockton to the customer there will be service level agreement for six months for one year that means while using the software if customer is facing any defect if customer is facing any problem and you want to change it it will be written in the service level agreement that we will be providing our maintenance to them for a period of six months or one year so we will be developing it developer will be developing it test engineers retested and we will give the new software to the customer over a period of how many bitter six on Somalia done once after service level agreement is over if customer wants to do any modification in the software they have to pay and get it so that is called a software development lifecycle I hope it is very I have explained in a very easy language if you have any question please reach out to me I have a my Jimmy rating the link description my Cora profile in the link description however my blog in description and you have any questions please reach
