Nokia is one of the most successful producers of mobile phone handsets in the world. It has the largest market share,sells the most phones and it has used this market share and its cost leadership to maintain the industry’s highest profit margins.
Nokia is a large global organisation. It employs more than 50,000 people in more than 100 countries, although 40% are employed in its country of origin, Finland.
About two thirds of the Nokia Group’s turnover is from mobile phone handsets, the remaining one third coming from its other business areas. The largest of these other areas is concerned with the infrastructure or networks, which connects mobile phones to one another and to other networks. Nokia also has a significant multimedia business group.
Nokia’s mission is ‘connecting people’. The company faces rapid changes in technology and customer needs in all its businesses areas, such as 3G, smartphones and the move to IP in networks. It faces strong competition in all of these areas and maintaining a leading market position is not easy. This explains why more than one third of Nokia’s employees work in Research and Development [R&D].
