Alasdair White refers to the "optimal performance zone", in which performance can be enhanced by some amount of stress. Beyond the optimum performance zone, lies the "danger zone" in which performance declines rapidly under the influence of greater anxiety.

performance management requires maximizing time in the optimal performance zone. The main target should be expanding the comfort zone and optimal performance zone. ==See also==
