Why is software evolution important?

Software evolution

The term software evolution was coined by Lehman and Belady in 1976. It refers to software systems and how they are maintained and enhanced in their entire life cycle, as the main goal in software engineering is to upgrade, migrate, and evolve currently existing software systems.

Evolution is an essential part of the software development life cycle. In software evolution, we have to modify the software depending upon the customer’s changing needs, market requirements, software defects being reported, or changes to other systems.

Importance

  • A large amount of resources are spent in an organization’s software.
  • Defects are found in existing software, which require fixing.
  • New features need to be added to the existing software to keep it up-to-date.
  • It is important to be continually improving the performance and reliability of software.
  • Security of the software must be upgraded in order to stay relevant and safe.
