This saying should be well-known to most people. Many people also apply this to strategy-making. It's not always easy to take care of every part to make sure that no part is the weakest link.

People can also find the weakest link first in solving a problem. This will definitely make the whole thing easier too.

From google search:

1. 鏈條的堅固程度取決於它最薄弱的環節。
2. 一著不慎,滿盤皆輸.


Tim,

Can I translate it into this: 凡事/人必有弱點?


Thank you.

Elinor,

This saying does not imply inevitabililty. So there's still some difference.

Tim

Tim,

Thanks a lot.


Elinor

It gives an implied meaning close to another saying:
一粒老鼠屎壞了一鍋粥.

A little grain of rat crap spoils the whole pot of porridge. The rat crap is like the weakest link of the chain.
