The film I, Daniel Blake, directed by Ken Loach, describes the administrative struggles of an elderly carpenter who suffered from a heart attack. After taking a work capability assessment he is deemed fit for work, even though his doctor does not allow him to return to work. He gets lost in the bureaucracy, because he is a computer illiterate and most of the forms have to be filled in online and are processed digitally. His case managers, bound by their preprogrammed decision systems, are unwilling and unable to empathize with him and to do justice to his personal circumstances.The story of Daniel Blake is a rather dramatic illustration of a general trend. The use of information technology (IT) has caused the discretionary freedom within large-scale public executive organizations to shift from professional case managers to programmers and data analysts. This is particularly true of the 'decision factories', those large-scale bureaucracies that routinely make decisions on social benefits, licences, tax returns, fines, subsidies and, to an increasing extent, permits. The same shift also seems to occur in law enforcement organizations that apply data science to optimize their resources and intervention strategies. Whereas previously, these organizations employed massive amounts of 'street-level bureaucrats', today these organizations are more properly understood as 'systemlevel bureaucracies' (Bovens and Zouridis 2002). In these 'system-level bureaucracies', the basic principle of 'unit production', which involved human judgement for each individual case, has been replaced by 'continuous process production' (Woodward 1958(Woodward /1975. Decision making by automated decision systems based on algorithms has pushed aside human judgements based on rules of thumb. In colloquial terms: it is the computer that says ´yes´ or ´no´.This chapter describes how information technology, such as automated decision systems and big data analysis, has transformed large executive organizations into system level bureaucracies. In these system level bureaucracies, the discretionary powers of the street-level professionals have been disciplined by digital systems, and the locus of administrative discretion has shifted to those responsible for programming the decision-making process and translating the legislation into software.Our analysis is limited to large 'production agencies' (Wilson 1989), such as the internal revenue services, departments for work and pensions, and social security agencies. We make no claims about more traditional street-level bureaucracies, such as the police, social work, schools, or courts -although some of the trends we describe can be observed there too. Intelligent and predictive policing are already transforming police organizations and shifting policing from street-level bureaucrats to systems designers and data analysts (e.g. Guilfoyle 2013). Even although police professionals still do street-level work, computer algorithms decide on where police capacity is send to and how policemen work. Data science a...
