What is Software Evolution?

The software evolution process includes fundamental activities of change analysis, release planning, system implementation, and releasing a system to customers. 

1. The cost and impact of these changes are accessed to see how much the system is affected by the change and how much it might cost to implement the change.
2. If the proposed changes are accepted, a new release of the software system is planned.
3. During release planning, all the proposed changes (fault repair, adaptation, and new functionality) are considered. 
4. A design is then made on which changes to implement in the next version of the system.
5. The process of change implementation is an iteration of the development process where the revisions to the system are designed, implemented, and tested. 

Software Evolution is a term that refers to the process of developing software initially, and then timely updating it for various reasons, i.e., to add new features or to remove obsolete functionalities, etc. This article focuses on discussing Software Evolution in detail.
