Volume 15 Article informations The mediating role of the intellectual capital in the relationship between organizational agility practices and innovation performance study by the role of intellectual capital in Tunisian SMEs Samar Ben Slimene , , Imen Fessi , , Lassaad Lakhal c Abstract Organizational agility is inevitably one of the most successful concepts in the field of management research as its stakes are decisive for organizations. One of the most frequent arguments is that it represents a lever for performance, particularly which is derived from innovation. Here, the question of intellectual capital also emerges as a theme that touches on this relationship. This study aims to conceptualize this link by suggesting that the organizational agility practices impact intellectual capital, thus producing higher innovation performance. We have empirically tested this model on the basis of a survey carried out in 110 Tunisian companies, using structural equation modeling via the (PLS) approach. The results highlight a partial mediating effect of the intellectual capital on this relationship. The study also reveals that agile practices particularly focused on strategic orientation, cooperation and the development of human resources which have a positive impact on innovation performance. Furthermore, customer orientation practices do not lead to the development of intellectual capital, as those of cooperation. The implications drawn from these results point in the direction of better taking into account by companies of the foundations of these agile practices to achieve competitive gains by innovating.
