Description: Review Groups in the context of Extreme Programming (XP) are teams dedicated to evaluating the code and progress of a software project. Their main goal is to ensure the quality of the final product and to guarantee that established standards are met. These groups function as a support network that fosters collaboration among developers, allowing for early identification of errors and implementation of improvements. Through regular reviews, group members can share knowledge, discuss approaches, and provide constructive feedback. This process not only enhances code quality but also promotes a continuous learning environment where developers can grow professionally. The dynamics of Review Groups are based on transparency and open communication, which helps build trust among team members. Additionally, by involving different perspectives in the review of work, biases are minimized and innovation is encouraged. In summary, Review Groups are an essential practice within Extreme Programming, significantly contributing to software quality and the professional development of team members.
