What is adaptive maintenance ?

Adaptive maintenance refers to the process of modifying a software system to keep it relevant and useful in a changing business or technical environment. This type of maintenance is necessary when there are changes in external factors such as hardware, software, business rules, or regulations that the software interacts with or operates under.

The goal of adaptive maintenance is to ensure the software continues to function correctly and efficiently after the external changes. It can involve changes to the code, reconfiguration of systems, or updates to accommodate new operating systems, platforms, or technologies that were not originally anticipated when the software was developed.
