The entire world is becoming increasingly globalised and internationalised due to different factors, mainly increased communication between countries and organisations. This increased internationalisation of companies has contributed to that companies now much easier can take advantage of opportunities all over the world than they could do in the past. We have in this thesis investigated both the prerequisites for expanding the business of a small Swedish high-technology firm selling ambulance information systems to foreign countries, and also which country is most suitable to start the internationalisation in for such a company. Our findings show that the main objectives for internationalisation are saturated domestic markets and to achieve faster economic growth. Furthermore we have found that it is very important to make a thorough marketing plan and analyse the markets carefully for the internationalisation to become successfully. Finally, the most suitable county to internationalise to for a small Swedish high- technology firm selling ambulance information systems and suggestions for further research are provided.
