depinde de context

a nu atinge standardul necesar, a nu fi la înălțimea așteptărilor, a nu fi de ajuns, a nu fi suficient de bun sau de eficient

Nu am gasit o expresie echivalenta in română insa cred ca s-ar potrivi sugestia mea.

SEMANTIC ENIGMAS

What is the origin of the phrase "doesn't cut the mustard"?
WHEN MUSTARD was one of the main crops in East Anglia, it was cut by hand with scythes, in the same way as corn. The crop could grow up to six feet high and this was very arduous work, requiring extremely sharp tools. When blunt they "would not cut the mustard". All this and everything else you could ever want to know about mustard can be found at the Mustard Museum in Norwich.

THE MORRIS Dictionary of Word & Phrase Origins (Harper Collins - 1988), relates the phrase to an earlier expression - "the proper mustard", meaning "the genuine article". Around the turn of the century, "to cut the mustard" meant to be "of high quality", as when O. Henry said of a pretty girl that "she cut the mustard all right". It is probably mere salaciousness which had me hunting through various lexicographical tomes in search of a connection, however tenuous, with the list of words cited by Jonathon Green in Slang Through the Ages (NTC, 1997), a list which included mustard-and-cress, lawn, grass, lawn, stubble and, most enduringly, bush.

Sensul expresiei este acela de „a nu fi suficient de bun”. În română, folosim uneori expresii de genul „nu ține (trebuie altceva), nu merge, nu corespunde” etc., cu același sens.
Bineînțeles că și contextul poate dicta o anumită traducere, dar sensul de bază este acesta.

Dacă se referă la persoane, se poate spune „nu face față”:

„If she can't cut the mustard, we'll have to find someone else to do the job.”
„We need a better catcher; this one just doesn't cut the mustard.”
