Variety (cybernetics) of "possible" states of a system, or of an element of a system", "cf." Ludwig Boltzmann's Wahrscheinlichkeit. Beer restates the Law of Requisite Variety as "Variety absorbs variety".

Beer used this to allocate the management resources necessary to maintain process viability. Variety is one of nine requisites that are required by an ethical regulator. In general a description of the required inputs and outputs is established then encoded with the minimum variety necessary. The mapping of input bits to
