It highlights the growing popularity of agile methodologies due to their iterative nature, stakeholder involvement, and adaptability to changing requirements. The essay discusses various agile methodologies such as Scrum, Extreme Programming (XP), and Crystal, evaluating their suitability for the VCI park system. While each methodology offers unique benefits, the essay concludes that Extreme Programming is particularly well-suited for the VCI project due to its emphasis on requirements identification, flexibility, and ability to accommodate changes, making it more effective than Crystal and Scrum in this specific context.
