Decision-making in institutional/professional settings has remained an established theme for social science and communication researchers. In contemporary western societies, the conditions of decision making are rapidly changing with the foregrounding of division of professional labour and distributed expertise against the backdrop of a client-centred ideology that legitimises shared decision-making. Increasingly, in health and social care settings, key decisions concerning clients are arrived at in team meetings, which have consequences both for the decisional processes and outcomes. This edited volume for the first time brings together a number of empirically grounded studies focusing on how team talk is functional to decision-making (in terms of problem formulation, generation of options, assessment of solutions etc.), with tensions, at the interactional level, between institutional and professional ways of categorising people, events and evidence.
