A program's user needs change with time. They are always changing in reaction to new regulations, new ideas, new goods, and new computing facilities, among other things. Correcting coding and design problems, updating documentation and test data, and enhancing user support are just a few of the actions that go under program maintenance. In other terms, maintenance may be thought of as enhancement, as it involves adding, altering, or building code to meet changes in the standards.

Modifications to a program system after its first release are referred to as program maintenance or software maintenance. It's the process of upgrading, changing, or correcting the system's applications. It is a crucial program development activity that consumes a substantial amount of a computer data processing company's resources.
