Adaptive software development is an Agile methodology that emphasizes flexibility, collaboration, and continuous improvement. Unlike traditional approaches, it doesn't rely on rigid frameworks or strict project plans. Instead, adaptive teams use iterative and incremental processes to deliver working software in short cycles. This approach allows for faster time-to-market, reduced risk, and increased customer satisfaction. Key characteristics of adaptive software development include self-organization, autonomous teams, and a focus on delivering working software in increments, rather than following a predefined timeline or budget.
