French Abstract: Cet article decrit une methode d'Action Learning pour enseigner l'intelligence situationnelle. Elle vise a aider les managers a trouver des reponses appropriees aux situations complexes de management qu'ils rencontrent. Apres avoir revu les differentes ecoles de pensee concernant le leadership et les meilleurs pratiques de management, nous definissons l'intelligence situationnelle comme l'intelligence des situations, de soi et des autres, et la capacite a reconcilier autant que possible les interets des differents acteurs impliques dans la situation. Nous utilisons les contradictions sous jacentes au management de conquete et au management de finesse comme cadre de reference. La methode "Fidelio", evolution de l'approche "Solfi" utilisee a HEC depuis 1999, utilise les theories du leadership et met l'accent sur des concepts recents ou recemment renouveles comme l'intelligence emotionnelle, la theorie des roles, les contradictions et les paradoxes, l'incertitude et l'ambiguite dans le management, etc. Les ressources pedagogiques consistent en un questionnaire, des ateliers, des entretiens individuels, et des rapports post-ateliers. Elles contribuent au developpement personnel, a la decouverte des concepts du management et a l'animation des equipes. Les participants experimentent differentes facon de se representer leurs situations et par consequent font evoluer leurs comportements de leadership. Ils prennent conscience que le leadership est contextuel et qu'il est necessaire d'utiliser des references theoriques. Ils travaillent aussi leur capacite a manager les contradictions.English Abstract: This article describes an Action Learning resource teaching situational intelligence. It aims to help managers find appropriate responses to complex management situations that they encounter. After reviewing different schools of thought concerning leadership and best management practice, we define situational intelligence as the intelligence of situations, others and oneself, and the ability to reconcile as well as possible the interests of the different actors involved in a situation. We use the contradictions underlying conquest management and finesse management as a reference framework. The "FIDELIO" method, an extension of the "SOLFI" approach used at HEC since 1999, uses leadership theories and stresses recent or newly revived concepts such as emotional intelligence, role theory, contradictions and paradoxes, uncertainty and ambiguity in management, etc. The teaching resource consists of a questionnaire, workshops, individual interviews and post-workshop reports. It contributes to personal development, to the discovery of management concepts and the communication of skills to staff. Participants experiment with different ways to represent their situations and consequently their leadership behaviors evolve. They become aware that leadership is contextual and that it is necessary to used conceptual references. They also work on their own ability to manage contradictions.
