  Software Evolution
  - The process of developing a software product using software engineering principles and methods is referred to as software evolution.
  
  - It includes the initial development of software and its maintenance and updates, till desired software product is developed, which satisfies the expected requirements.
  
  - The evolution process starts from the requirement gathering phase.
  
  - After this the developers create a prototype of the intended software and show it to the users to get their feedback at the early stage of software product development.
  
  - The users suggest changes, on which several consecutive updates and maintenance keep on changing too.
  
  - This process changes to the original software, till the desired software is accomplished.
  
  - Even after the user has desired software in hand, the advancing technology and the changing requirements force the software product to change accordingly.
  
  - Re-creating software from scratch and to go one-on-one with requirement is not feasible.
  
  - The only feasible and economical solution is to update the existing software so that it matches the latest requirements.
