Since there is a universally acceptable standard benchmark, a deviation from the ideal type reveals the unintended fault lines and the extent to which the system can no longer function as a bureaucratic administration, as expected.
A variation in the ideal structure of a bureaucracy, anywhere, is an aberration; and it generates or produces contaminated contents and a distorted organisation.
In a bureaucracy, the Mafia paradigm that often emerges in a political system suggests a variation or an adulterated variant of bureaucracy, though a powerful one. Usually, this paradigmatic shift from the ideal type is motivated by the leadership structure of the executive arm of government and the subtle intervention of the political class. Once the inbuilt systemic check of a bureaucracy fails, the corrupt version takes roots and gains prominence.
