"Crozier's breakthrough book, The Bureaucratic Phenomenon (1963 in French, 1964 in English), is a still wonderful account of how an organisation as a system generates the overlapping vicious circles that then block the system. The voices of his interviewees in two public service organisations, one a clerical agency, the other a state industrial monopoly, explaining their attitudes and their behaviour, are as fresh as if they had been uttered yesterday. This book heralded a consistent theme in Crozier's work that organisational reform is not possible unless its proponents take into account the way that people will interpret it, react to it and subvert it. As Crozier put it in the title of a 1979 book: "You can't change a society by decree.""
