This report investigates and compares SCRUM and Rapid Application Development (RAD) methodologies for system development, specifically in the context of an organization developing a mobile application. It details the characteristics, phases, benefits, and drawbacks of both methodologies, highlighting the importance of agile, flexible, and scalable products. SCRUM, with its sprints, daily stand-ups, and product backlogs, is contrasted with RAD's requirements planning, user design, and construction phases. The report recommends SCRUM due to its enhanced clarity, work prioritization, reliability, scalability, and adaptability, which ensures better risk management, cost control, and end-user satisfaction. It also touches upon the potential for scope creep and the necessity for self-motivated teams in SCRUM projects.
