Advantages of Iterative Waterfall Model

Following are the advantage of Iterative Waterfall Model:

1. Phase Containment of Errors: The principle of detecting errors as close to their points of commitment as possible is known as Phase containment of errors. 
2. Collaboration: Throughout each stage of the process, there is collaboration between the business owners and developers. This ensures that the website meets the needs of the business and that any issues or concerns are addressed in a timely manner.
3. Flexibility: The iterative waterfall model allows for flexibility in the development process. If changes or new requirements arise, they can be incorporated into the next iteration of the website.
4. Testing and feedback: The testing stage of the process is important for identifying any issues or bugs that need to be addressed before the website is deployed. Additionally, feedback from users or customers can be gathered and used to improve the website in subsequent iterations.
5. Scalability: The iterative waterfall model is scalable, meaning it can be used for projects of various sizes and complexities. For example, a larger business may require more iterations or more complex requirements, but the same process can still be followed.
6. Maintenance: Once the website is live, ongoing maintenance is necessary to ensure it continues to meet the needs of the business and its users. The iterative waterfall model can be used for maintenance and improvement cycles, allowing the website to evolve and stay up-to-date.
7. Easy to Manage: The iterative waterfall model is easy to manage as each phase is well-defined and has a clear set of deliverables. This makes it easier to track progress, identify issues, and manage resources.
8. Faster Time to Market: The iterative approach allows for faster time to market as small and incremental improvements are made over time, rather than waiting for a complete product to be developed.
9. Predictable Outcomes: The phased approach of the iterative waterfall model allows for more predictable outcomes and greater control over the development process, ensuring that the project stays on track and within budget.
10. Improved Customer Satisfaction: The iterative approach allows for customer involvement and feedback throughout the development process, resulting in a final product that better meets the needs and expectations of the customer.
11. Quality Assurance: The iterative approach promotes quality assurance by providing opportunities for testing and feedback throughout the development process. This results in a higher-quality end product.
12. Risk Reduction: The iterative approach allows for early identification and mitigation of risks, reducing the likelihood of costly errors later in the development process.
13. Well-organized: In this model, less time is consumed on documenting and the team can spend more time on development and designing.
14. Cost-Effective: It is highly cost-effective to change the plan or requirements in the model. Moreover, it is best suited for agile organizations.
15. Simple: Iterative waterfall model is very simple to understand and use. That’s why it is one of the most widely used software development models.
16. Feedback Path: In the classical waterfall model, there are no feedback paths, so there is no mechanism for error correction. But in the iterative waterfall model feedback path from one phase to its preceding phase allows correcting the errors that are committed and these changes are reflected in the later phases.

In a practical software development project, the classical waterfall model is hard to use. So, the iterative waterfall model can be thought of as incorporating the necessary changes to the classical waterfall model to make it usable in practical software development projects. It is almost the same as the classical waterfall model, except some changes are made to increase the efficiency of the software development.
