If everything went to plan today (without me) then you should have learned about the three different types of maintenance that can occur after a program has been released.
These are:
Perfective – adding new features to improve the software (e.g. Sims updates!)
Corrective – fixing problems in the software that should have been taken care of during development!
Adaptive – altering the software to work on new computer systems or in new environments
All of these occur after the software has been released.
