The probability that a failed unit will be repaired within a given amount of time. The term is also used to denote the discipline of studying and improving the maintainability of products, primarily by reducing the amount of time required to diagnose and repair failures.
The probability that a given maintenance action for an item under given usage conditions can be performed within a stated time interval when the maintenance is performed under stated conditions using stated procedures and resources. Maintainability has two categories: serviceability (the ease of conducting scheduled inspections and servicing) and repairability (the ease of restoring service after a failure).
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 ease with which the system/software can be modified to correct faults, modified to meet new requirement s, modified to make future maintenance easier, or adapted to a changed environment.
The ability of a component or an IT service, under stated conditions of use, to be retained in, or restored to, a state in which it can perform its required functions. Maintainability also describes maintenance being performed under stated conditions and using prescribed procedures and resources.
The ease with which software can be changed and updated.
characteristic of design and installation which inherently provides for an item to be retained in, or restored to a specified condition within a given period of time, when the maintenance is performed in accordance with prescribe procedure s and resources. [D00967] USDoD QMPP The ability of an item to be retained in or restored to specific conditions when maintenance is performed by personnel having specific skill levels, using prescribe procedure s and resources, at each prescribe d level of maintenance and repair.

The ability of an item to be retained in or restored to a specified condition when maintenance is performed by personnel having specified skill levels, using prescribed procedures and resources.
The ease with which a software system (or system component) can be modified to correct faults, improve performance, or other attributes, or adapt to a changed environment.
The capability of an item to be retained in or restored to specified conditions when maintenance is performed by personnel having specified skill levels, using prescribed procedures and resources, at each prescribed level of maintenance and repair. MTFL, MCMTOMF and MR are frequently calculated in maintainability evaluations.
The ease to maintain equipment.
