    • Facilitates a collaborative environment, fostering open communication and mutual understanding.
  3. Continuous Delivery:
    • Promotes regular, incremental releases of functional software, allowing for ongoing feedback and improvements.
    • Ensures that working software is delivered to customers regularly, maintaining momentum.
  4. Collaboration:
    • Emphasizes teamwork, fostering better communication, problem-solving, and idea exchange.
    • Encourages a sense of shared ownership among team members, enhancing project cohesion.
  5. Early and Frequent Testing:
    • Identifies issues and bugs early in the development process, enabling prompt resolution.
    • Streamlines development by preventing the accumulation of unresolved problems.

Limitations of Agile Software Development

  1. Lack of Predictability:
    • Outcomes and schedules can be less predictable due to Agile methodologies' iterative and adaptive nature.
    • Less certainty about the final product and its delivery schedule can be challenging for some projects.
  2. Limited Documentation:
    • Reduced emphasis on extensive documentation can pose challenges in tracking changes and understanding system architecture.
    • Balancing agility and comprehensive documentation is essential to maintain clarity and knowledge transfer.
  3. Time and Resource Constraints:
    • Demands a significant commitment of time and resources from all team members.
    • Balancing project demands with team availability can be intricate, requiring careful resource management.
  4. Less Emphasis on Planning:
