Explanation:

Formal organizations are designed to achieve certain goals through the collective work of the individuals who are its members. They rely on a division of labor and hierarchy of power and authority to ensure that the work is done in a unified and efficient manner. Within a formal organization, each job or position has a clearly defined set of responsibilities, roles, duties, and authorities to whom it reports.
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)
