The disorder contained can only cause the complexity in the organization, disorder outside organization has the influence to organization complexity, but it cannot cause the organization the complexity, only if it is absorbed and in the organization, can the disorder constitute the complexity; all nature of the complexity is produced because of the disorder in the organization, if there is no the disorder, the organization has no nature such as fortuitousness, randomness, multiplicity and non-linearity, and it is impossible to appear the perturbation, the fluctuation, emerges with phenomenon such as branch, and cannot change suddenly and evolve.
