Framgångsfaktorer för stora infrastrukturprojekt

Sammanfattning: The success of large infrastructure projects is of importance for the development of society. This type of project has furthermore an inherent complexity and is hence difficult to implement successfully. This thesis investigates and analyses success in large infrastructure projects together with characteristics for successful infrastructure projects. The aim of the study is to understand what constitutes a successful infrastructure project, identify success factors for infrastructure projects and to study how companies should work with these factors to create successful projects. To fulfil the purpose of the thesis, a comparative case study of two similar infrastructure projects in a consulting company is conducted. The empirical base for the thesis is data from qualitative interviews together with the critical incident technique. The results show that expectations are a crucial part of what success means in these projects and met expectations from all stakeholders is what constitutes a successful project. This thesis identifies five success factors which are: leadership and management, planning, resources and resource allocation, feedback and reflection and also cooperation and dialogue.  Furthermore, the result shows that the best way to work with these factors is by using an iterative approach. Finally, this study indicates that iterative practices in large infrastructure projects is beneficial and future research should examine how the implementation of these practices can and should be done in practice.
