I would say that one of the more modern forces that drive bureaucratic reform is the need for government to assist its citizens during the current economic challenges. Initiatives such as the government bailout are attempts at reform from the "top down," where modern bureaucracy is seen as a source of help and assistance. Assessing the success of measures such as these is largely dependent on one's point of view. There are those who feel that the government cannot help with such situations and that its presence can only make a bad situation worse. On the other side of the debate are those who feel that these problems are large enough that only government could alleviate the burdens of those in such a predicament.
Bureaucracy and and bureaucratic reforms are common around the world. It appears the question refers to some specific organization and bureaucratic reforms that have taken place in over a given period. Without identification of these details, is not possible to discuss them. Therefor in may answer below, I have covered bureaucracy and bureaucratic reforms i general.
The term bureaucracy primarily referred to the system of management and administration proposed by the German Sociologist and economist Max Weber (1864-1920). This model of administration has greatly influenced the systems and procedures for management and administration of large organizations including the governments and other public organizations. Because of use of bureaucratic system of administration used, the government organizations as well as the systems and procedures followed by governments across the world are called "bureaucracy".
Though the basic system of bureaucracy had many good points, it also has many limitations, which tend to slow down and delay the work. Because of this the term bureaucracy is also associated with long cumbersome procedures, delays and inefficiencies.
Governments and other public organization around the world recognize the limitation of their bureaucracy and try to improve their system and procedures. Any such major efforts are termed as bureaucratic reforms. Starting from late 20th century many countries in the world have undertaken major bureaucratic reforms in the form of introducing computer based systems to improve speed and efficiency of government departments.
