In the face of increasing globalization and significant changes in the last year, each organization must have a clearly defined strategy for developing and building process effectiveness. The article aims to identify factors influencing the selection of processes subjected to lean management, implemented in Shared Services Centers (SSC) in the Wielkopolska region. To achieve this goal, selected definitions of this concept were presented with a focus on creating a culture of continuous improvement. Based on a review of Polish and international literature, the principles of selecting the processes subjected to this methodology were discussed. Based on expert interviews, preliminary considerations were made on the barriers to selecting processes subjected to lean management in the Wielkopolska region. As presented in the article, it may be helpful, in the context of process selection, to use the achievements in the field of process management and risk management, which are most often not associated with this concept. The article presents the direction for further research: to assess the effectiveness of lean management in terms of processes that have been transformed as a result of process redesign.
