This collection presents a critical dialogue on managerialist forms of government between philosophy, political thought, organisational and management theory. The volume brings together essays that are concerned with technologies of government that are articulated as different iterations of managerialism. The hallmark of managerialist discourse is value, considered as a quantifiable abstraction, where the intention is to always ‘add value’. The central question addressed here by a team of international expert authors from across a range of disciplines is this: in what ways has this abstraction of value impacted on the substantive work and ethical integrity of government and the public sector, and, more broadly, of the professions (including that of management itself)? Has it displaced this work, or simply recast it? The volume addresses audiences in social sciences, philosophy, management, business, and organisational studies.
