The aim of this paper is to explore the relationship between the adoption of Information Technologies (IT) and the adoption of New Organizational Practices (NOP) in the context of an emerging country (Tunisia). Based on face-to-face questionnaire, to a random sample of 175 Tunisian manufactures, and using an ordered logit model, our empirical results show a significant link between IT adoption and NOP. We show that the complementarity is strengthened when the technology evolves. Adoption and usage of latest technologies are pushed by the prior adoption of NOP.
