Object-oriented analysis and design (OOAD) is a software engineering approach that models a system as a group of interacting objects. Each object represents some entity of interest in the system being modeled, and is characterised by its class, its state (data elements), and its behavior.

What do you mean by object oriented analysis?

Object-oriented analysis and design (OOAD) is a technical approach for analyzing and designing an application, system, or business by applying object-oriented programming, as well as using visual modeling throughout the software development process to guide stakeholder communication and product quality.

Why object oriented analysis is important in software engineering?

The most important purpose of OO analysis is to identify the objects of a system that have to be implemented. This analysis can also perform for an existing system. An efficient analysis is only possible when we think in a way where objects can be identified.
