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.
waterfall model is good when we have a clear understanding of requirements.
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.

∙ 9y agoThe waterfall model is also known as the linear sequential model. This model is very easy to implement, and output is generated after every stage. However, real projects usually don't follow the flow in the model.

∙ 11y ago- You always have a running version of the program, eg, if you run out of time, you can deliver the last iteration, which may not have all functionality, but it does something. This is usually worth more to your instructor than a program which doesn't compile or run.
- Errors are easier to findbecause they are most likely in that last little bit of code that you added.
- It's psychologically more satisfying to get positive feedback on your work, ie, a running program.
- Corrections early in development generally take less time than later in the development process.
- A disadvantage of iterative programming is that it tempts you to start coding before you have a clear idea of what you want to do. Think about the problem a little bit before you start. This design process becomes more important as programs become larger.

∙ 9y agoIn the case where it is a simple project with well defined requirements and with very little likelihood of them changing during the development, then the Waterfall model is good. Each step can be completed before moving on to the next with a very small chance that any stage would have to be gone back to. An iterative model is more likely to be used in more complex systems where there is a greater likelihood for the requirements to change.

What is the iterative waterfall?
Iterative waterfall model is a software process model also called the incremental process model. http://en.wikipedia.org/wiki/Iterative_and_incremental_development
Deference between classical waterfall model and iterative waterfall model?
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.
Waterfall or spiral model of railway reservation system?
spiral model is iterative model hence its easy to implement it .
What are the traditional lifecycle models for software development?
The primary one is called "Waterfall" because it all goes one way, never back.
What is the limitation and advantages of iterative model of sdlc?
In iterative model we get an end product at the end of each iteration. Iterative model is not so efficient and time consuming.

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.
List few of the System Development methodologies?
agile methodology, spiral, iterative, waterfall, model-driven development architecture

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 are the different types of SDLC?
1. Waterfall Model 2. Spiral Model 3. Iterative Model 4. Prototype Model 5. RAD Model 6. COCOMO Model 7. V-Model 8. Fish Model
Stages of information systems development?
The Waterfall Model: A classic SDLC model, with a linear and sequential method that has goals for each development phase. The waterfall model simplifies task scheduling, because there are no iterative or overlapping steps. One drawback of the waterfall model is that it does not allow for much revision. the waterfall model is made up of 7 steps: Analysis-> Design-> Implementation-> Testing-> Documentation-> Evaluation-> Maintenance remember it this way: A Dance In The Dark Every Monday!
