This document provides an introduction to the Software Development Lifecycle (SDLC), focusing on the three main models: Waterfall, Spiral, and Iterative. It explores their histories, advantages, and challenges, offering guidance on when to use each model based on project characteristics such as requirements stability and risk level. The Waterfall model is explained in detail with sequential phases including requirements gathering, design, implementation, verification, and maintenance. The Spiral model is presented as a risk-driven approach emphasizing early risk management and customer feedback integration, while the Iterative model highlights continuous improvement through repeated cycles. Activities and case studies encourage learners to apply their understanding of these models in practical scenarios, fostering critical thinking in software development methodology selection.
