Management research considers knowledge as one of the first sources of competitiveness of the company. This observation is at the origin of development in recent years, the Knowledge-Based View (Grant, 1996), resulting from the resource-based perspective approach. This research examines the importance of internal sources of knowledge and its relationship with organizational innovation and organizational performance. We did this research on a sample of 200 Tunisian companies operating in different sectors. Our study was built mainly on the basis of quantitative method. The data collection method is the questionnaire as part of a hypothetical-deductive approach and the mode of administration is self-administered survey and e-mail survey. The empirical verification of the assumptions of this research has led us to confirm the relationship between internal and external sources of knowledge with organizational innovation and organizational performance and to infirm the relationship between organizational innovation and organizational performance.

The focus of the current study is analyze the impact of the use of ICT on the performance of Tunisian companies. These companies must be always fully aware of the importance of a practical valorization of ICTs that bring about socio-economic development. Thus, using ICTs on Tunisian companies’ performance has unquestionably remained a vital need. In fact, this study is carried out on a sample of 150 Tunisian companies operating in different business sectors. We chose the quantitative method. So, to test our conceptual model, we applied the exploratory factor analysis and then the structural equation methods. The empirical testing of hypotheses of this research led to partially confirm the influence of ICTs on the performance of Tunisian companies. In this regard, the companies surveyed are almost aware of the importance of the value of ICT, which implies an insufficient use of ICTs and an incomplete maturity of this field.

De nos jours, les entreprises considèrent la formation des salariés comme la pierre angulaire de leurs politiques et de leurs stratégies de gestion, pouvant maintenir les employés à un niveau de connaissances, d’intelligence et de compétences assez conséquentes. Sur la base de ce constat, nous avons cherché à mesurer l’impact de la formation des salariés sur la performance organisationnelle, à travers une recherche effectué sur un échantillon de 270 entreprises tunisiennes. Pour réaliser ce travail, les méthodes d’équations structurelles ont été utilisées pour tester notre modèle conceptuel, non sans avoir envisagé des analyses factorielles exploratoires suivies d’analyses factorielles confirmatoires.
