The competition in international markets has led to a situation where industrial maintenance services are increasingly outsourced. Many regional clusters have fragmented into global value chains, in which geographically scattered companies specialize in particular activities. At the same time, the competition has changed from being between companies to being between networks (or chains). As a result, more attention has to be paid to sharing the value between all the network members and keeping the whole network competitive. Most of the existing management tools are not directly suitable for networks, because they have been designed for individual companies. There is a need for practical tools to manage maintenance service networks to increase the value of the cooperation of the network members.
