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 else can I help you with?
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 advantage of using prototyping model instead of using waterfall model?
There are many advantages of using prototype model over waterfall model . Some of the advantages are: 1) Excellent for gathering and refining requirements. 2) Useful for assessing and reducing risks.
What is the difference between waterfall model iterative waterfall model prototyping model and spiral model?
There are 2 main methods of software modeling · Predictive(e.g.waterfall) - Good when requirements are well understood and have low technical risk. · Adaptive(e.g.spiral) - Good when requirements and needs are uncertain. High technical risk In a failure - In a predictive LC it will be expensive because we get to know the failure after finishing everything but in adaptive LC only an iteration is wasted. There several phases in the waterfall model a. Planning b. Requirements c. Specification (b and c together we call analysis) d. Design e. Implementation f. Maintenance This is called a Functional Decomposition and also a top down approach (Where we see from above and identify the big picture first and then go in to higher details) In the waterfall model, before going to the next phase we have to freeze the previous step (no turning back). This is good when we have a good understanding about the project at the beginning. But iterative models gives us more flexibility through giving chance to revisit early phases. Spiral model is a adaptive model. This is an adaptive SDLC that cycles over and over again through development activities until project is complete. Here we go through some major steps, 1. Plan 2. Analyze and Design 3. Construct prototype 4. Test and integrate These steps iterate till completion of the project. This is also can be viewed as a divide and conquer approach. In first few iterations complex or risky parts of the system are handled.
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 costly).
Waterfall model advantages and disadvantages?
Advantage of waterfall model : It is simple and easy to use. Dis Advantage of waterfall model : no user feedbacks are taken.
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 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.
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 Compare the two methodologies Waterfall and System Prototyping models?
The Waterfall model is a linear and sequential approach to software development, where each phase must be completed before moving on to the next, making it easy to manage but inflexible to changes. In contrast, the System Prototyping model emphasizes iterative development, where prototypes are created and refined based on user feedback, allowing for greater adaptability and user involvement throughout the process. While Waterfall is suited for projects with well-defined requirements, System Prototyping is ideal for environments where requirements are expected to evolve. Ultimately, the choice between the two depends on the project's complexity and the likelihood of requirement changes.
What is Iterative waterfall method?
The Iterative Waterfall method is a software development approach that combines elements of the traditional Waterfall model with iterative cycles. In this method, the project is divided into distinct phases, like in the classic Waterfall, but each phase can be revisited for refinement based on feedback or changes in requirements. This allows for greater flexibility and adaptability, enabling teams to enhance the product incrementally while still following a structured progression through the project stages. It balances the need for a clear timeline with the ability to respond to evolving project needs.
Waterfall or spiral model of railway reservation system?
spiral model is iterative model hence its easy to implement it .
List few of the System Development methodologies?
agile methodology, spiral, iterative, waterfall, model-driven development architecture
Explain what linear programming is and what the various models are?
the sequential flow of processes usually linear and its has two types which are: Waterfall and Prototyping Model
Waterfall model is suitable for which system with justification?
SDLC + Software Prototyping commonly used to develop organisational information systems
What is incremental model explain in detail?
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.
