ما معنى Hard limit, soft limit, limit utilisation, limit breach؟

A hard limit is a limit that must not be exceeded: an excess must be cured at once, by reducing the exposure, or escalated for an approved increase. A soft limit is a lower threshold whose crossing triggers a warning and a review, not a mandatory action. Limit utilisation is the exposure as a share of the limit. A limit breach is an exposure above a hard limit, recorded with its size, duration and resolution.
