Definition of "performant"

A ballet visibly stresses the performant function even though, traditionally, it also claims to communicate some meaning. In sports, the performant function dominates more openly; but, in a symbiotic relation, it derives much of its vitality from a grafted referential function that operates through cultural signs. [...] As a rule, however, the performant function, when it is supported by truly impressive circus performances, tends to monopolize the audience's attention.
