Based on knowledge-based theory of organizational capabilities and dynamic capabilities theory, this paper tries to establish the linkages between tacit knowledge resources, its integration into firm level capabilities, product innovation and firm performance. In this way, the paper analyses the relationships between some of the most relevant variables to the organizations in order to remain competitive. The conceptual model is tested using a sample of organizations in the industrial sector, using SEM and hierarchical regression analysis. Results show a positive relationship between tacit knowledge and firm performance, tacit knowledge and product innovation, and product innovation and firm performance. A partial mediating effect of product innovation on the tacit knowledge firm performance relationship is established. Also, technical capabilities have a moderator effect on tacit knowledge firm performance relationship. At the end of the paper managerial implications are commented, as well directions for future studies.

The resource-based view (RBV) posits that the sustainability of a firm's success depends upon the creation, development, and implementation of a given organization's unique resources and capabilities. Based on this theoretical framework, this article analyzes the relationship between organizational capabilities, business strategy, and profitability in the Portuguese textile industry. The strong relationship between these variables suggests that the organizational capabilities and the choice of business strategy may be the key to increase the profitability in this study context. So, the ability of the Portuguese textile organizations to change their business strategy based on their organizational capabilities affects profitability in a number of ways. Concretely, the results of this study highlight the importance of the choice of the business strategy as a partial mediator between the organizational capabilities and the profitability, a point that is crucial to understanding the success of a given organization and how resources and capabilities contribute to the process. The article concludes with a number of managerial implications and directions for future research.
