Formal rules are often adapted to subjective interests—social structures within an
enterprise and the personal goals, desires, sympathies and behaviors of the individual workers—so that the practical everyday life of an organization becomes
informal. Practical experience shows no organization is ever completely rule-bound: instead, all real organizations represent some mix of formal and informal. Consequently, when attempting to legislate for an organization and to create a formal structure, it is necessary to recognize informal organization in order to create workable structures. However, informal organization can fail, or, if already set in order, can work against mismanagement. Formal organizations are typically understood to be systems of coordinated and controlled activities that arise when work is embedded in complex networks of technical relations and boundary-spanning exchanges. But in modern societies, formal organizational structures arise in highly institutional contexts. Organizations are driven to incorporate the practices and procedures defined by prevailing rationalized concepts of organizational work and institutionalized in society. Organizations that do so increase their legitimacy and their survival prospects, independent of the immediate efficacy of the acquired practices and procedures. There can develop a tension between on the one hand, the institutionalized products, services, techniques, policies, and programs that function as myths (and may be ceremonially adopted), and efficiency criteria on the other hand. To maintain ceremonial conformity, organizations that reflect institutional rules tend to buffer their formal structures from the uncertainties of the technical activities by developing a
loose coupling between their formal structures and actual work activities. - (John Meyer and Brian Rowan, 1976) == Identification numbers and public registers ==
