Institutional Theory views institutions as comprising of regulatory, normative, and cultural-cognitive elements that provide stability and meaning to social life. It understands that institutions must interact with surrounding social systems. There are two dimensions of institutional change - isomorphism, where an institution changes to resemble others facing similar conditions; and decoupling, where formal practices separate from actual operations. Isomorphism can occur through coercive, mimetic, or normative pressures on institutions to conform to social expectations.
