The Analysis of Situations by Scenarios - The Example of Quality Campalgns in Organisations. Scenarios are brief discourses submitted to a survey population. This method constitutes a useful manner for obtaining statements and discourse from the respondents. It helps reveal norms and rules of action about which individuals talk little and for which it is difficult to obtain information. The method can complement and enrich data obtained by more classic methods such as interviews. Through the comments and arguments of these respondents or actors, the method obtains access to the different logics of action revealed by the responses and the judgements provided in the framework of the proposed situations. The method can also reveal the capabilities mobilized by respondents in relation to the different problems encountered during work and also access the different forms of expertise used by cach member of an organization in daily activity.
