This thesis attempts to support the healthcare information systems producer, ABC, in its aim to expand beyond the borders of its saturated home market. With the success of such an internationalisation plan, ABC could overcome the challenge of its national growth cap and reach out to international development opportunities. In the recent past, however, the company has based international operations on opportunistic decision making rather than a solid internationalisation framework. Considering the complexity of internationalisation, this work aims to (i) develop a systematic and quantified scoring method to evaluate the potential and attractiveness of new markets, (ii) apply this method to ABC’s preselected countries and (iii) evaluate the elected best solution. Applying the scoring model identified the Netherlands as the high potential target country. However, the final in-depth evaluation has to conclude a necessity for further preparation of ABC before expansion.
