Replaceability
Replaceability is the property of a component, system, or process that allows it to be substituted by another compatible component or version to restore or maintain functionality when the original is unavailable, obsolete, or degraded. It is closely linked to maintainability and modular design, and it depends on standard interfaces, documentation, and the availability of suitable substitutes.
Key factors include compatibility, interchangeability, lead times, cost, performance, and supply-chain reliability. Modular design and standardized
In manufacturing and software, replaceability supports maintenance strategies, upgrades, and lifecycle management. Examples include spare tires
Replaceability is distinct from substitutability in that replaceability is a property of a system’s ability to
