Canning published "The Maintenance 'Iceberg '", in which he contended that software maintenance was an extension of software development with an additional input: the existing system. [1]
LTS applies the tenets of reliability engineering to the software development process and software release life cycle.Long-term support extends the period of software maintenance; it also alters the type and frequency of software updates to reduce the risk, expense, and disruption of software deployment, while promoting the dependability of the software.
Maintenance and support: After the software is deployed, ongoing maintenance and support become crucial to address any issues, enhance performance, and incorporate future enhancements. Regular updates, bug fixes, and security patches are released to keep the software up-to-date and secure.
