1. RAD Model :
RAD model refers to Rapid Application Development and it is type of Incremental Model. The components or functions are developed in parallel and it can handle small project as well as medium project. In this model any changes can be made in any stages. It has high productivity due to less number of people.
2. Incremental Model :
Incremental Model is a model of software development where the product is, analyzed, designed, implemented and tested incrementally until the product is finished. Multiple development cycles take place and these cycles are divided into more smaller modules. Generally a working software in incremental model is produced during first module Each subsequent release of the module adds function to the previous release. In incremental model, process continues till the complete system is achieved.
Difference between RAD Model and Incremental Model :
|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.|
