The object-oriented programming is quite useful in many ways. It has various advantages, some of which are mentioned below.

Since object-oriented structuring provides a closer representation of reality than other programming techniques, complex software systems become easier to understand.

In object-oriented system, it should be possible to implement changes at class level, without having to make alterations at other points in the system. This reduces the overall amount of maintenance required.

The object-oriented programming allows reusing individual components through polymorphism and inheritance. 

In this system, the amount of work involved in revising and maintaining the system is reduced as many problems can be detected and corrected in the design phase.

To achieve these goals, the followings are required:

Object-oriented programming languages: The efficiency of object-oriented programming depends directly on how object-oriented language techniques are implemented in the system kernel.

Object-oriented tools: Object-oriented tools allow you to create object-oriented programs in object Oriented languages. They also allow you to model and store development objects and the Relationships between them.

Object-oriented modeling: The object-orientation modeling of a software system is the most important, most time-consuming, and most difficult requirement for attaining the above goals. These designs involve more than just object-oriented programming and logical advantages that are independent of the actual implementation are provided by it.
