Agile Methodology Quiz

Guidance: This principle directs the team to focus on delivering working software in frequent, small increments that provide tangible value to the customer from an early stage. It shifts the focus from completing all features at once to providing a steady stream of useful functionality.
Example: Instead of waiting six months to deliver a complete application, an Agile team might deliver a core feature set within the first month, allowing the customer to use it and provide feedback, which then informs subsequent development.
