How the waterfall model and prototyping model can be accommodated in the spiral process model?
Expalin different between waterfall model and prototyping model ? Expalin different between waterfall model and prototyping model ?
Waterfall or spiral model of railway reservation system?
spiral model is iterative model hence its easy to implement it .
Spiral model is known as meta model justify?
piral Model is called meta model because it is composed of several other models.For example a single loop spiral actually represent the Waterfall Model.The spiral model uses prototyping approach before embarking on the actual product development effort.Also the spiral model can be considered as supporting the evolutionary model-the iterations along the spiral can be considered as evolutionary levels through which the complete system is built.This enables the developer to understand and resolve the risks at each evolutionary level.The spiral model uses prototyping as a risk reduction mechanism and also retain the systematic step approach of waterfall model.(
What is the diffference between waterfall model and modified waterfall model?
Modified waterfall model verified and validate the user requirements for every phase. Meanwhile, waterfall did not, it only verify and validate user requirement at the end of the phase.
What is the Difference between RAD model and waterfall model?
The RAD model, also known as the Rapid Application Development, is a linear software for creating prototypes. The Waterfall model is a sequential software.

Waterfall model and prototyping model can be accommodated in spiral model?
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.

What is the difference between waterfall model iterative waterfall model successive model prototyping model and spiral 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
Difference between spiral and waterfall model?
Spiral model is iterative and allows for gradual development through repeated cycles of planning, designing, building, and testing. Waterfall model, on the other hand, follows a linear sequential approach where each phase must be completed before moving on to the next. Spiral model is more flexible and suitable for projects with high uncertainty, while waterfall model is best for well-understood, stable projects.
What is difference between incremental model and spiral model?
spiral model is just like incremental model but in spiral emphasize is on risk analysis.

Why spiral model is called U process model?
because, there can be back process of every step in waterfall model, see the book of software engg by somerville.
Explain how both the waterfall model of the software process and the prototyping model can be accommodated in the spiral process model?
the waterfall model gives us prototyping , and spirl model gives us product , so the set of the waterfall accommodat in the spirl to gives us this product.
What is the difference in changing the scope between a spiral approach and a waterfall approach?
I believe the scope of requirements changes in Waterfall model is less than that in Spiral Model. In Waterfall model, you progress to the next stage only when the requirements of the stage above it are finalized and signed off. So litteraly we dont have any scope of changing the requirements once we move down the phases in this model.However, Spiral model gives us flexibility to change the requirements and scope anytime during the life cycle.In this model we implement the individual requirements following all the standard phases of Software Life Cycle. So if any new change is there, we can implement it in next version of the software.
List few of the System Development methodologies?
agile methodology, spiral, iterative, waterfall, model-driven development architecture
What is the diffference between waterfall model and modified waterfall model?
Modified waterfall model verified and validate the user requirements for every phase. Meanwhile, waterfall did not, it only verify and validate user requirement at the end of the phase.
