a camel is a horse designed by a committee

ことわざ

An expression critical of committees — which by analogy can extend to both group decision-making as well as abstract or unrelated managerialism — by emphasizing the weaknesses of incorporating too many conflicting and inexperienced opinions into a single project. The distinguishing features of a camel, including its humps, plate-shaped feet, habitual spitting, strange shape and poor temperament, are treated as the sort of deformities that typify a conflicted, or overly idealistic, design process.
