The ease with which the information system can be adapted to new demands from the user, to changing external environments, or in order to correct defects.
The probability that a failed system can be made operable in a specified interval or downtime.
(1) a developer-oriented quality requirement specifying the degree to which minor defects can be corrected correctability and minor enhancements can be made extensibility between major releases to an application or component while it is in use by its users.(2) a quality factor measuring the degree to which minor defects can be corrected and minor enhancements can be made between major releases to an application or component while it is in use by its users.
