This chapter discusses joined-up government and its effect on the civil service. The focus is on the different silo mentalities which are used to connote not being joined-up. In this chapter particular attention is given to the indiscriminate attack on silo and the implication that ‘everyone is guilty’ which leads to the avoidance of careful diagnosis of problems. Discussed herein are the different types of silo mentalities that exit on the basis of some of the academic literature. The chapter also discusses the different consequences that might arise from the silos including the consequences brought about by the silos into the typology of patterns of non-joined-up government. The chapter ends with a discussion on the implications of this typology to the civil service reform including the possible positive aspects of these implications.
