јннотаци€:  The Law of Requisite Variety is a mathematical theorem relating the number of control states of a system to the
number of variations in control that is necessary for effective response. The Law of Requisite Variety does not
consider the components of a system and how they must act together to respond effectively. Here we consider the
additional requirement of scale of response and the effect of coordinated versus uncoordinated response as a key
attribute of complex systems. The components of a system perform a task, with a number of such components
needed to act in concert to perform subtasks. We apply the resulting generalizationЧa Multiscale Law of
Requisite VarietyЧto understanding effective function of complex biological and social systems. This allows us
to formalize an understanding of the limitations of hierarchical control structures and the inadequacy of central
control and planning in the solution of many complex social problems and the functioning of complex social
organizations, e.g., the military, healthcare, and education systems.
