RAD模型和瀑布模型的区别

瀑布模型：
瀑布模型也称为经典或传统模型。有时它被称为线性顺序生命周期模型，因为该模型中涉及的所有阶段都以线性方式一一完成。在这个模型中，我们在完成所有编码阶段后得到软件。这种模式主要用于小型项目。瀑布模型中只有一个循环。

雷达型号：
RAD 模型代表快速应用程序开发，它是增量模型的类型。它不能处理大型项目，但可以处理小型项目和中型项目。在 RAD 模型中，任何更改都可以在任何阶段进行，但在瀑布模型中是不可能发生的。

RAD模型和瀑布模型的区别：

S.No	Waterfall Model	RAD Model
1.	Waterfall model known as Classical/Traditional Model.	RAD stands for Rapid Application Development.
2.	There is high amount risk in waterfall model.	There is low amount risk in RAD model.
3.	In waterfall model large team size is required.	In RAD model small team size is required.
4.	Waterfall model can’t handle large project.	RAD model also can’t handle large project but usually it is preferred between large and small project.
5.	Any changes can be made in waterfall model only at the beginning.	Any changes can be made in RAD model anytime.
6.	The product of Waterfall model is delivered after the completion of all stages.	The product of RAD model is delivered as soon as possible.
7.	There is long waiting time for running software in waterfall model.	There is less waiting time for running software in RAD model, as its first version is released as soon as possible.
8.	Waterfall model is not compatible with the change in client requirements.	RAD model may work with the change in client requirements.
