SDLC evolutionary model also known as incremental model. We will discuss today about why this model is known as incremental model and what is the importance of this model.
Certain facts that needs to be taken into consideration while discussing about it.
In this development model the requirement is broken down into different functional units which in turn is also considered as module.These modules can be incrementally built and delivered.
The very first point of build will be the core functionality.
New functionality is built, added to existing one and released as new version.Each successive version is capable of performing more functions in comparison to its previous versions.
As the model seems to be developed in the incremental way so it is termed as incremental model of the development.
Evolutionary model is suitable for Object oriented software development product. Its because in OOP requirement can be separated in different modules in terms of the objects.
