The Object-Oriented Systems Development Lifecycle

Unlike the strictly linear phases of the Waterfall model, Bahrami proposes an iterative and incremental lifecycle for OOSD. He organizes this lifecycle into three major macro-processes, supported by continuous iteration: Introduction

Bahrami stresses that encapsulation and inheritance are not just technical features but design disciplines. Check SlideShare / Academia

Suddenly, the city needs a "Police Car." Instead of designing it from scratch, they use Inheritance. They take the existing "Vehicle" blueprint and just add sirens and radios. When they need a "Motorcycle," they use Polymorphism, so the "Start Engine" command works for both a car and a bike, even though the internal mechanics are different. The Result: A Robust System

Ali Bahrami Object-Oriented Systems Development (OOSD) is a seminal framework in software engineering that focuses on modeling systems using real-world entities represented as objects. His approach is widely used in academic and professional settings to bridge the gap between requirements and implementation through a systematic, modular, and reusable process.
