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.
prototype model is suitable when user requirement are not very clear, while spiral model suitable for large projects whether customer requirement are not known in the beginning
spiral model is just like incremental model but in spiral emphasize is on risk analysis.
The win-win spiral approach is very similar to the spiral model in that it is simply an extension of the spiral model. In the win-win model approach, everyone discusses things together to figure out what should go into the new version of the software.

spiral model is iterative model hence its easy to implement it .
The spiral model is called a meta model since it encloses all other life cycle model.
The spiral model is called a meta model since it encompasses all other life cyclemodels. Risk handling is inherently built into this model. The spiral model issuitable for development of technically challenging software products that areprone to several kinds of risks. However, this model is much more complex thanthe other models - this is probably a factor deterring its use in ordinary projects.The spiral model is called a meta model since it encompasses all other life cyclemodels.

In spiral model the main emphasis is on the management to evaluate and resolve risks in the software project. There is no maintenance phase in spiral model because instead risk is evaluated .
There are many differences exists between waterfall model and spiral model. In waterfall model if any sudden change takes place in the project, then its very hard to fix the issue. Wherein spiral model we can change according to our requirement.
It can be a realistic model in many cases, so the question is pointless unless it refers to some specific situation.
Spiral model was developed by Dr. Barry Boehm . This model was mainly used to evaluate and resolve risks in the software project.
