spiral model is just like incremental model but in spiral emphasize is on risk analysis.

Provide three examples of software projects that would be amenable to the incremental model. Be specific.
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.

I will try to answer this quickly as I don't have much time. As the name suggests, the waterfall model follows the path of an waterfall. It starts in the first stage of orientation, and ends at the release. It can only go one way (to the end goal) and the stages are very strict (you cant go back to a earlier stage). The Spiral model understands that reality doesn't always follow theory, and that an project should be designed to follow that reality. There are multiple prototypes released, and phases can be repeated until the desired result is reached (hence the spiral). The iterative model combines those two, making (IMHO) the waterfall model more ready for the real world. You should try googling yourself, I found lots of info about the differences in this article about the advantages of the waterfall model: http://www.waterfall-model.com/the-waterfall-model-avantages-and-disadvantages
Prototype model is the best way to understand customer's requirements. A prototype is re- generated until it meets the expectations of the user
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
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.
It's uml base model usely use of use case design and spiral model Risk driven approchs
The evolutionary software process model involves working with the customers. It starts by specifying clear requirements of the software and features suggested by the customer are added later during development.
In incremental model the real product is designed, implemented, integrated and tested as a series of incremental builds. while In prototype model the prototype (not the real product) is designed, implemented, integrated and tested as a series of incremental builds
RDA is Rapid Application Development which emphasizes on short development where Incremental is completing one complete phase then move to the second phase means increment by one..
The waterfall development model is primarily used by large software companies. The incremental model is used by small companies and individuals.
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.
bhag tum logo ko kuch nahi atta hai..... why i should give the answer
Yes, it is possible to combine the software process models. Some possibilities to combine software process models are given below: Evolutionary process model. Incremental process model. The spiral model.
incremental process model is used whenever you want to have a working copies of iteration on your work. BOOM!
it is the combinatin of the rational comprehensive and the incremental decision making models.
