The Uppsala model explaining internationalization of the firms only looks at process from single angle of experiential knowledge which makes the model too simple for study of the internationalization process. In the course of the paper the Uppsala model is enhanced to look at pre internationalization of process and finally the export readiness is developed. Several internationalization models aimed at study of export readiness place emphasis on learning, resource allocation and decision-making as three main components of the export readiness. The experiential knowledge has been added to the model. The models are innovation and experiential model are models describing the internationalization process as series of incremental decisions and commitments. The theories explaining staged process of internationalization see the process as interplay between knowledge acquisition and market commitment.
