What is the disadvantage of iterative waterfall model?
The 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.
Iterative waterfall model is a software process model also called the incremental process model. http://en.wikipedia.org/wiki/Iterative_and_incremental_development Read More
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. Read More
Classical waterfall model involves sequential steps of software development life cycle.The complete product is retrieved at the end.However, in Iterative waterfall model, the customer receives modules of the project before the completion of the complete project. The final product is received at the end only. Read More

What are the advantages and the disadvantages of a waterfall model Also how do you overcome the disadvantage of a waterfall model?
An Advantage is that it is reasonably good for new projects and it is a good model to teach The Main Disadvantage of the waterfall model is that it does not allow for very much Iteration. for example you are in the testing stage and you realize that something has not been designed correctly. In theory if following the model as closely as possible and trying to make it iterative this would lead you back… Read More

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.

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… Read More
In 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… Read More
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… Read More
In iterative model we get an end product at the end of each iteration. Iterative model is not so efficient and time consuming. Read More
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… Read More

The incremental build model is a method of software development where the model is designed, implemented and tested incrementally (a little more is added each time) until the product is finished. It involves both development and maintenance. The product is defined as finished when it satisfies all of its requirements. This model combines the elements of the waterfall model with the iterative philosophy of prototyping. Read More

What is the basic difference between iterative enhancement model and evolutionary development model?
The Iterative Enhancement Model is an approach to building software in which the overall lifecycle is compose of several iterations in sequence. The Evolutionary Enhancement Model is designed to be allowed to evolve in response to the customers' feedback. Read More

Waterfall model uses sequential design process, in which each phase is tested in level by level like a waterflow from top to bottom. In waterfall model once we come out of the phase, there is no possibility to change something according to the new requirement, once the phase is done then it is just done. Waterfall model is applicable for small projects. Read More

A waterfall model is a process that was used to develop and manufacture a product before computers became so commonplace. Because it was too cost prohibitive to make changes after the fact, a company used a waterfall model to develop their product. The stages of a waterfall modes are: Conceive, Design, Implement, Test, Deliver. Read More
Iterative model is used when tight market deadlines make completion of a comprehensive software product impossible, but a limited version must be introduced in order to meet competitive or business pressure; a set of core product or system requirements are well understood, but the details of product or system extensions have yet to be defined. In these and above situations, a process model is required that has been explicitly designed to accommodate a product that… Read More
What is the main Criterion for deciding whether or not to use waterfall model in a software development project?
The critieria is based on what other techniques you might employ. The waterfall method in SDLC (software development life cycle) has been largely discounted in favor of more effective methods, such as the iterative approach. One of the main problems with the waterfall design is that it does not easily allow for negative feedback at several stages of the project (for example, water flows downhill, not uphill, so feedback into the cycle can be very… Read More
