Extensibility and flexibility
Extensibility and flexibility are additional characteristics related to maintainability. The level of extensibility reflects how easy it is to extend or enhance the software system. Software systems that are designed to be extensible take future growth into consideration by anticipating the need to add new functionality.
Flexibility is similar but mostly focuses on how easy it is to change a capability so that it can be used in a way that wasn't originally designed. Both extensibility and flexibility are characteristics that dictate the level of ease with which someone can perform perfective maintenance.
