Iterative waterfall model is a software process model also called the incremental process model.
http://en.wikipedia.org/wiki/Iterative_and_incremental_development
Major difference between waterfall and iterative model is that waterfall model has a linear process in which full product is available after the last phase, while incremental model full product is available after several such phases.
spiral model is iterative model hence its easy to implement it .
The primary one is called "Waterfall" because it all goes one way, never back.
In iterative model we get an end product at the end of each iteration. Iterative model is not so efficient and time consuming.

Incremental model is good when we have to deliever the final product wihin certain timeline and we have very less number of programmers available to complete the product in time, so basic idea is to deliever a working partial product within time and provide it's additional functionalities later.

The Iterative Waterfall method is a software development approach that combines elements of the traditional Waterfall model with iterative cycles. In this method, the project is divided into distinct phases, like in the classic Waterfall, but each phase can be revisited for refinement based on feedback or changes in requirements. This allows for greater flexibility and adaptability, enabling teams to enhance the product incrementally while still following a structured progression through the project stages. It balances the need for a clear timeline with the ability to respond to evolving project needs.

Hello: It depends on what you would like to call as an upgraded version. XP and the super set - Agile is much more than just iterative and incremental. You can check out this article found out by a Google search for more: http://www.agilecollab.com/iterative-and-incremental-is-not-equal-to-agile-key-aspects-of-agile Thanks
1.spiral model can be accommodate in prototyping and waterfall model. it is a model of iterative process as prototyping and also a systematic approach to solve a problem as in waterfall model. 2. spiral model take problem as a series of step to solve a problem as in waterfall, and take the contribution of users or customers in each phase as in prototyping model.
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
The key differences between the sprint and waterfall methodologies in project management are in their approach to planning and execution. Waterfall follows a sequential, linear process where each phase must be completed before moving on to the next, while sprint is iterative and allows for flexibility and adjustments throughout the project. Waterfall requires detailed planning upfront, while sprint focuses on delivering working increments of the project in short, fixed time frames.
