Description: A feature set is a collection of functionalities and capabilities that a product offers to meet user needs. In the context of agile methodologies and Extreme Programming (XP), this concept becomes crucial as it focuses on the continuous delivery of value to the customer. Features are defined based on user requirements and prioritized according to their importance and impact on user experience. This approach allows development teams to quickly adapt to changes in customer needs, ensuring that the final product not only meets expectations but also evolves over time. Features can range from basic capabilities to complex interactions, and their proper implementation is fundamental to the project’s success. In agile methodologies, constant collaboration between developers and users is encouraged, facilitating the identification and adjustment of these features throughout the development lifecycle. In summary, a feature set is essential to ensure that a product is not only functional but also provides a satisfying and relevant user experience.
