RAD模型和增量模型的区别

1. RAD 型号：
RAD 模型是指快速应用程序开发，它是增量模型的类型。组件或功能是并行开发的，它可以处理小型项目和中型项目。在此模型中，可以在任何阶段进行任何更改。由于人数较少，因此生产率高。

2.增量模型：
增量模型是一种软件开发模型，在该模型中，产品以增量方式进行分析、设计、实施和测试，直到产品完成。发生多个开发周期，这些周期被划分为更小的模块。通常，增量模型中的工作软件是在第一个模块期间生成的。该模块的每个后续版本都会在先前版本的基础上增加函数。在增量模型中，过程一直持续到实现完整的系统。

RAD模型和增量模型的区别：

S.No.	RAD Model	Incremental Model
1.	Rad model is a software development model where by the components or functions are developed in parallel as if they were mini projects.	Incremental Model is a software development model where the product is, analyzed, designed, implemented and tested incrementally until the product is finished.
2.	Rad model requirements and early stage planning is not necessary.	In incremental model requirements and early stage planning is necessary.
3.	RAD model is used between large and small project.	Incremental model can’t handle large project.
4.	There is low amount risk in RAD model.	There is also low amount risk in incremental model.
5.	In RAD model small team size is required.	In incremental model large team is not required.
6.	Flexibility to change in rad model is Easy.	Flexibility to change in incremental model is Easy.
7.	In rad model overlapping of phases is possible.	In incremental model overlapping of phases is possible.
8.	Testing is done in rad model after completion of coding.	Testing is done in incremental model after every iteration of phase.
9.	Returning to previous stage/phase in rad model is possible.	Returning to previous stage/phase in incremental model is possible.
10.	Cost of rad model is also Low.	Cost of incremental model is also Low.
