There is a lot of major advantage of using the incremental model to develop software. As to full fill the requirements of a customer. The incremental model gives software for the customer as he wanted it to be. As it is a modified version of developing the software, so nowadays it is the most common process of developing software. As human behaviour, we need anything as quick as possible, and this process of developing software offers us all that need which we need. And if any implementation is demanded by the customer then it has very easy to change and implement that particular thing as the customer demands it to be. These are the major advantage of using the incremental model:-
Software development in module wise
In the process of developing software by using an incremental model, the software delivers to the customer module wise to know the requirements of the customer. At first, developers deliver the core model of software to the customer to know either it is the need of the customer as he desired to be developed or not. It offers software to the customer module wise.
It doesn’t offer the whole software to the customer at a time. And this is the reason why it is now the most common process of developing software. Because it gives the customer to see how his software is developing by offering him software in module wise. And also it helps the developer to know the requirements of the customer.
Requirements and feedback of the customer
Requirements of the customer are most important while developing the software by using the incremental model. Without knowing the requirements of the customer software can’t be developed by using the incremental model. As it delivers the software in module wise, so when it delivers the core model of software to the customer then the developers get feedback from the customer about that software.
Developers give one after another module to the customer to know the feedback of the customer and also to know the requirements of the customer if he needs to change anything and need to be done any implementation in that particular software. As the customer gives the feedback to the developers then it also helps the customer if he needs any implementation. So the customer gets satisfied with the software as he gets the software in module wise and gives his feedback to the developers and then at the feedback of the customer, the developers develop the software.
Interaction with the customer
When developers develop software in module wise and deliver every module to the customer then the interaction between the customer and developers have more and due to this interaction between the customer and developers, the results have very much effective. This means the customer gets the software as he wants to be the software to develop.
And also due to this interaction between the developers and the customer, developers have much more idea about which type of software the customer needs to be. After every module of the software, this interaction between the customer and developers increase. And both the developers and the customer have an idea about how his software developing and what the customer demanding. So this interaction plays a very important role while developing the software to know more about the demands of the customer.
Delivery of the core model
The customer gets early delivery of the software in module-wise of the core model. Human behavior demands the product as quickly as possible. And in this process of developing software by using an incremental model the customer gets delivery of the core model of software early. So the customer has no need to wait for a long time for his software completely developed.
The customer can access his software as he gets the software in module-wise, so he can use that module of software and give his feedbacks regarding every particular module of software. As in other methods of developing software the customer doesn’t get his software as quick as it delivers to the customer. And this one is also a reason to become a very common process of developing the software.
As if the customer gets the delivery of the software early so he will have well known how his software is going to develop. And the main motive of delivering the software early is to make the customer know how his software developing and to know the feedback of the customer. As software has developed module wise so if the developers won’t deliver it earlier then it will take a lot more time to complete the whole development of software and to know the feedback of the customer regarding every other module. So delivery of the software earlier is most important while developing the software by using the incremental model.
Payment of the software
The customer has no need to pay the whole payment of software at a time. He has to pay after every module of the software. If one module of software has been completed and the customer is satisfied with that particular module of the software only then the customer has to pay for that module of software.
So in this process of developing software the customer no load to pay a large amount of money at once for the whole software. As after every other stage the customer has to pay for it. In case if he is not satisfied with that particular module of software then he can give his feedback to the developers and can convince him to need to implement it in that particular module. And after that implementation, if the customer is satisfied then only he has to pay. It is also a major advantage of using the incremental model, that the customer has no need to pay a bulk amount at a time for the whole software.
Work with small size team
As the developers have no need to deliver the whole software at a time so the developers can work with a small size team. It is not necessary to have a large team for developing the software by using the incremental model. Because after every module the developers get feedback from the customer so it has become easier for the developers to develop the software.
And for that, if the developer has small size team then also he can develop the software. As in this process of developing software, the developers has well known about the requirements of the customer and after every module, the developers gets feedback from the customer. So it has not much more difficult for the customer to develop the software. And because it has not much more difficult so it’s not necessary to have a large team for developing the software.
Accommodate changes
In this process of developing software, the customer gets the module of software so if he wants to implement anything in that module then the customer can easily implement it. And the implementation cost has very less, so the customer can implement anything it wants to be. And this is also a reason to become the more popular process of developing software.
Because in this process the customer can easily implement anything in their software if the customer wants and the implementation cost has also very less. As in another process of developing software, there has no such facility to implement anything and at less cost as this process offers.

Conclusion
From the above discussion about the advantages of the incremental model, it is clear that it is the very common process of developing software and the software offers to the customer module-wise. If a customer needs to implement anything in any particular module then the customer can easily implement it at a very low cost.
And the delivery of software has earlier as compared to any other model of developing software. These advantages differ from every other module. It can say a modified version of developing software. And due to all these reasons nowadays it has considered as the most common process of developing software.
