”A chain is no stronger than its weakest link.”
processes, organizations, etc, are vulnerable because the weakest person or part can always damage or break them; a successful group or team relies on each member doing well
موفقیت یک گروه وابسته به عملکرد خوب تمام اعضای آن است .
Example : George is completely out of shape. I don’t want him on our ball team; a chain is only as strong as its weakest link
