Between Defining and Disseminating Policy Solutions

Using an empirical study of the implementation of a tramline in Paris, the article assesses the influence of discursive practices in decision-making. Furthermore, it highlights three dimensions of a discourse in ‘action’ which plays a key role : 1/ as a definitional and analytical practice to produce meaning and shape a ‘coherent’ statement ; 2/ as a practice of persuasion to propagate this statement and structure a discursive coalition ; 3/ as a conflicting power practice to redefine the topography of positions. The policy-making process, understood as the analysis of games of language, actors, and positions, must be considered as a major political activity during which a government tries to put order in society.
