maintainability
Ease of upkeep
Maintainability is how easily something can be kept in working order.
In software engineering, maintainability measures how readily code can be updated, debugged, or modified: The team prioritized maintainability over clever optimizations.
In manufacturing, it refers to how efficiently equipment can be serviced.
High maintainability reduces long-term costs and extends useful life.
