The waterfall model is a linear model that follows a sequence as activities move from one to another. The spiral model is a circular model that breaks software development into smaller segments.

∙ 12y ago"Waterfall model is a document driven process. While spiral model does not requires the document." Is this mentioned anywhere? Because at the end of the last prototyping in spiral modeling, water fall model process ( like detail design, coding, testing, acceptance) is applied, and hence it should also be considered as document driven process. Please comment. Yes I agree that spiral modeling will help client to understand the approximate characteristics of end product and on the basis of which he can rework on the requirements and hence it is suitable for big projects with high risk factor involved.

What are the differences between the steadystate model of the universe and the big bang model?
The steady state model assumes that new matter is created at the universe expands, the big bang theory states that no new matter is ever created, but only changes form.
What is the main difference between geocentric and helicentric models of the solar system?
Geocentric model that was prevalent in the middle ages said that the Earth was in the center of the solar system (in fact of the universe) and all other planets revolved around it. Modern science says that in the solar system the Sun is at the center and all its planets revolve around it.
How does a model of the solar system in which the planets have elliptical orbits explain the difference in the speed of the planets?
The model doesn't just say the orbits are elliptical, it gives more details. Following Kepler's three laws it can be said that the average speed is inversely proportional to the square root of the major axis.
What is a model of planets orbiting called?
A model of the solar system.A model of the solar system.A model of the solar system.A model of the solar system.
Why has the heliocentric model been replaced with the geocentric model?
The heliocentric model is the one that replaces the geocentric model because the heliocentric model better described the solar system.
What are the similarities between waterfall model and spiral model?
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.
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 ?
What is difference between incremental model and spiral model?
spiral model is just like incremental model but in spiral emphasize is on risk analysis.
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.
Waterfall or spiral model of railway reservation system?
spiral model is iterative model hence its easy to implement it .
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
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.
Difference between spiral model and win win spiral model?
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.
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.
What are the difference between Rational Unified Process and Spiral model?
It's uml base model usely use of use case design and spiral model Risk driven approchs
What is difference between Spiral model and Prototype?
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 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.(
