Required Skills of the Systems Analyst

Object-Oriented Systems Analysis and Design

Software engineering approach Models a system as a group of interacting objects

Object-Oriented Analysis (OOA) Process of analyzing a task (also known as problem domain) to develop a

conceptual model that can then be used to complete the task

Object-Oriented Design (OOD) Mapping of the analysis model into implementation classes and interfaces

to create a model of the solution domain (i.e., a detailed description of how the system is to be built)

Object-Oriented Programming (OOP) Use to implement the solution
