When conducting process related work within an organization, it is important to be aware of which factors that are most important to consider. This paper presents an empirical study that was performed in order to find the key success factors in process management. One factor, namely synchronization of processes, was considered as much more important within the studied organization than within the studied literature. This shows that more research might be needed in this area. The study further shows that it is important to relate process improvement work to the properties of the affected organization and that the key factors identified are highly interrelated.
