One of the commonly encountered uses of the term in technical fields is the phrase "Managing programmers is like herding cats" or "Managing engineers is like herding cats".

It refers to the individualism common in the stereotypical examples of programmers and domesticated cats. A similar phrase, allegedly of Irish origins, is "Minding mice at a crossroads".
