The goal of prototyping based development is to counter the first two limitations of the waterfall model discussed earlier. The basic idea here is that instead of freezing the requirements before a design or coding can proceed, a throwaway prototype is built to understand the requirements. This prototype is developed based on the currently known requirements. Development of the prototype obviously undergoes design, coding and testing. But each of these phases is not done very formally or thoroughly. By using this prototype, the client can get an "actual feel" of the system, since the interactions with prototype can enable the client to better understand the requirements of the desired system.
Prototyping is an attractive idea for complicated and large systems for which there is no manual process or existing system to help determining the requirements. In such situations letting the client "plan" with the prototype provides invaluable and intangible inputs which helps in determining the requirements for the system. It is also an effective method to demonstrate the feasibility of a certain approach. This might be needed for novel systems where it is not clear that constraints can be met or that algorithms can be developed to implement the requirements. The process model of the prototyping approach is shown in the figure below.
what are the phases of the sdlc
The moon has different phases that it passes through, just like we have different phases in our lifetimes.
Moon Phases , or Lunar Phases.
Phases* 8 Phases

One advantage of prototyping is the fact that you can make changes to the model before building the actual model. One disadvantage of prototyping is that it can take too long.
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.
It is One Of the Prototyping model.
Prototyping model is one of the software development life cycle model. In this we prepare a prototype before the actual product.
In prototyping the main principle is that the project is built quickly to demonstrate the customer who can give more inputs and feedbacks . Prototype model is excellent for gathering and refining requirements.
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.
Rapid prototyping is a process where a working model or prototype is developed for the purpose of testing the various product features like design, ideas, features, functionality, performance, and output. This process of development of the working model is quite quick. I had taken help of rapid prototyping service of Iannone3D, which is a New Jersey-based Rapid Prototyping and 3D Printing Service Bureau. Thanks.
The phases in the waterfall model are in Iswr and overlapped is true.
What are the 4 phases the DAGMAR model
The spiral model is used by reputable companies such as IBM, Microsoft, Patni Computers and Tata Consultancy where large projects are involved.
the sequential flow of processes usually linear and its has two types which are: Waterfall and Prototyping Model
