This article discusses the importance of environments for managers’ successful introduction of a new management technique. Two empirical examples illustrate the interrelatedness of external and internal environments and its consequences for the propensity of organizations to accept and implement managerial propositions. It is suggested that an intrusive external environment, which clearly relates to generally accepted facts, facilitates managerial action and makes organizations change prone. Mangers, who seek to forestall future environmental problems, in contrast, seem likely to meet with a hostile and conservative internal environment. In both instances managers depend on the social construction of the external environment of their organizations.
