1.Each phase of an iteration is rigid with no overlaps
2.Costly system architecture or design issues may arise because not all requirements are gathered up front for the entire lifecycle

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 water fall model incremental model?
Water fall modelwaterfall model always attempt to start with full requirementsWaterfall model is linear process flow execution.Each five framework activities in sequentially flow beginning with communication and culminating with deployment.In this linear process you can't go back.Doesn't response to resources.Inefficient used of resources.The waterfall model some time called the classic life cycle as well as linear process model/sequential model.In waterfall model more time spend in documentingIncremental modelIncremental model is process of repetitions developed in smaller chunks.An iterative life cycle model doesn't attempt to start with full requirements.This process is repeated producing a new version of software for each cycle of the model.In this incremental process you can go back.we are build the product step by step. W e can track the defects at early stages.This avoid the down word flow of the defects.In iterative model less time spend on documenting.example: Agile,XP (Extreme programming),scrum.
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.
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
What is difference between agile model and iterative model?
nothing
Which process model suitable for development project?
Iterative
What is an iterative process model?
a model that goes back to an earlier step in the process
What software process model can be applicable for online bookshop?
You can use Iterative model.
Waterfall or spiral model of railway reservation system?
spiral model is iterative model hence its easy to implement it .
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.
Advantage and disadvantage of v shape model?
Advantage and disadvantage of "v shape model"?
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.
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
Where iterative model is used?
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 evolves over time. Iterative model provides the best help in such situation.
