Which of these is not a key value of Agile software development?

Comprehensive documentation is not considered a key value in Agile software development because the Agile methodology prioritizes working software over comprehensive documentation. Agile focuses on delivering valuable software quickly and responding to change, rather than spending excessive time and effort on documenting every detail. Instead, Agile emphasizes the importance of collaboration, communication, and face-to-face interactions to ensure that everyone is on the same page and working towards the common goal. While Agile acknowledges the need for minimal documentation, it does not advocate for comprehensive documentation as it can be time-consuming, may become quickly outdated, and can hinder agility and adaptability.
