Answer #1

Software Maintenance is the process of modifying a software product after it has been delivered to the customer. The main purpose of software maintenance is to modify and update software application after delivery to correct faults and to improve performance.

Need for Maintenance –
Software Maintenance must be performed in order to:

  • Correct faults.
  • Improve the design.
  • Implement enhancements.
  • Interface with other systems.
  • Accommodate programs so that different hardware, software, system features, and telecommunications facilities can be used.
  • Migrate legacy software.
  • Retire software.

Perfective maintenance: Modification of a software product after delivery to improve performance or maintainability. Preventive maintenance: Modification of a software product after delivery to detect and correct latent faults in the software product before they become effective faults.
