Meaning:You use this proverb to say that if too many people do the same thing (job, project,, etc.), it will not be done well.
Sometimes people just say, "Too many cooks. "
Another proverb "There is safety in numbers" expresses the opposite idea.
If someone says, "Too many cooks spoil the broth," he/she means that your work will be more efficient if you use fewer people.
Example:
The director never asks more than 10 people to work with him in his projects, and he wants the best 10. He always says, "Too many cooks spoil the broth."
