Too many cooks spoil the broth.
An excess of contributors degrades the outcome.
What They Mean
Work needs ownership. Every additional hand brings an additional opinion, and broth cannot survive committee.
Are They Right?
In kitchens and meetings alike, yes. Coordination costs rise faster than capacity, and eventually the pot contains nothing but suggestions.
What They Left Out
One cook can spoil the broth without any assistance whatsoever.
