An agile project management approach is defined by its iterative and incremental methodology, emphasizing flexibility and collaboration. Rather than following a strict sequential process, agile promotes adaptive planning and rapid delivery of functional components. Key characteristics include regular sprints, where teams work on short cycles to produce deliverable increments, which are reviewed and refined based on stakeholder feedback. This approach fosters a close relationship between development teams and clients, increasing satisfaction and allowing for continuous improvement as project requirements evolve over time.
