Which Agile methodology emphasizes adaptability and customer collaboration over strict planning?

Scrum is an Agile methodology that emphasizes adaptability and customer collaboration over strict planning. It encourages iterative development, frequent feedback, and a focus on delivering value to customers. Scrum teams are self-organizing and cross-functional, with a Scrum Master facilitating the process rather than dictating tasks. This approach promotes flexibility, continuous improvement, and customer satisfaction by responding to changing requirements throughout the development cycle.
