It could be also defined as a way to capture only those details about an object that are relevant to the current perspective.

What is Object-Oriented Analysis (OOA)?
Grady Booch has defined OOA as, “Object-oriented analysis is a method of analysis that examines requirements from the perspective of the classes and objects found in the vocabulary of the problem domain”. The primary tasks in object-oriented analysis (OOA) are:
