    (VF)Les principes de validité externe et de validité interne de l’étude de cas sont souvent présentés comme deux dimensions indépendantes. Cet article ambitionne de dépasser ces approches dichotomiques pour étudier les rapprochements possibles entre validité interne et validité externe. Il s’appuie sur une analyse approfondie de ces concepts et des tactiques visant à les renforcer, au cours des différentes phases qui ponctuent le processus de recherche. Nous émettons l’hypothèse selon laquelle, si les principes de validité interne et externe se différencient aisément, la convergence de leurs tactiques conduit à leur renforcement mutuel.(VA)The principles of external validity and internal validity of case study research are often considered as two independent dimensions. This article aims at overcoming this opposition in order to study the possible links between internal and external validity. The paper is based on the analysis of these concepts and of the specific tactics to enforce them. We study these tactics during the various phases which punctuate the process of research. We make the assumption that the principles of internal and external validity are fundamentally different, but the convergence of their tactics leads to their mutual reinforcement.
