OOP focuses more on the objects that programmers desire to handle than on the logic necessary to do so. Large, sophisticated, and actively updated or maintained applications are a good fit for this kind of development. This includes mobile apps as well as production and design software. OOP, for instance, can be utilized in manufacturing system simulation software.
