Why spiral model is more realistic?

The spiral model is considered more realistic because it incorporates iterative development and risk management, allowing for continuous refinement of requirements and design based on user feedback. This adaptability enables teams to address uncertainties and changing needs throughout the project lifecycle. Additionally, by emphasizing incremental releases, it aligns better with real-world complexities and promotes a more collaborative approach to software development. This flexibility enhances the overall quality and relevance of the final product.
