Abstract
This chapter comprehensively compares the Waterfall and Agile software development models, focusing on methodologies, effectiveness, and adaptability for different projects. Using research and case studies, it details each model's unique traits, strengths, and limitations, offering insights for managers, developers, and stakeholders. The Waterfall Model follows a linear, sequential approach divided into phases: requirements, design, implementation, testing, deployment, and maintenance. Its systematic nature suits projects with fixed, well-defined requirements where predictability is crucial, allowing effective resource management. In contrast, Agile is flexible and iterative, broken into short cycles emphasizing client involvement and teamwork. Ideal for dynamic environments with evolving requirements, it supports innovation, customer satisfaction, and user-focused solutions through regular client feedback. In conclusion, the document advocates for a flexible application of these methodologies, encouraging leaders to adapt based on project demands.
