Agile Development Questions Medium
Agile Development and Prototype model are both software development methodologies, but they have some key differences.
1. Approach: Agile Development follows an iterative and incremental approach, where the development process is divided into small iterations called sprints. Each sprint delivers a working software increment. On the other hand, the Prototype model focuses on building a prototype or a mock-up of the final product to gather feedback and refine the requirements.
2. Requirements: Agile Development emphasizes on adaptive planning and welcomes changes in requirements throughout the development process. It allows for flexibility and encourages collaboration between the development team and stakeholders. In contrast, the Prototype model aims to gather requirements upfront and build a prototype based on those requirements. Changes in requirements are not as easily accommodated in this model.
3. Feedback: Agile Development promotes continuous feedback and collaboration with stakeholders. The development team regularly showcases working software increments to gather feedback and make necessary adjustments. In the Prototype model, feedback is primarily sought after the prototype is built and demonstrated to stakeholders. This feedback is then used to refine the requirements and build the final product.
4. Time and Cost: Agile Development focuses on delivering working software increments in short iterations, allowing for early and frequent releases. This approach helps in managing time and cost effectively. On the other hand, the Prototype model may require more time and resources to build the prototype before the actual development begins, potentially increasing the overall time and cost of the project.
5. Flexibility: Agile Development is highly flexible and adaptable to changes in requirements, allowing for continuous improvement and evolution of the software. The Prototype model, on the other hand, may not be as flexible as it is based on a predefined prototype that may limit the scope for changes.
In summary, Agile Development and Prototype model differ in their approach, requirements handling, feedback process, time and cost management, and flexibility. While Agile Development focuses on iterative development, flexibility, and continuous feedback, the Prototype model emphasizes building a prototype upfront to gather requirements and may have limited flexibility for changes.
