An Interoperable Fare Management system for public transport has been a struggle for the actors in industry of public transport. A lot of effort has been put into creating a smart card solution that enables the travellers to use the same card for paying and holding the ticket regardless geographical position in Sweden. That project has failed, mostly due to a lack of taking non-technical actors and aspects into consideration during the project process. This thesis highlights the major actors and their responsibilities. The ARKTRANS framework is used as analytical tool to identify different roles. Throughout the thesis a sociotechnical perspective is used. The developed method in this thesis is suitable for mapping of actors and responsibilities in a network surrounding a complex technical system.
