This study investigates the implementation of Lean principles to Value Stream Mapping (VSM). The study also explores the benefits and challenges of applying VSM as a mapping model for preliminary work in the context of digitalization within assembly lines. Through a qualitative approach, including literature review and interviews, this research examines the integration of Lean principles with VSM as a framework to uncover and address inefficiencies at a large company assembly line. The study was done at a large enterprise (LE) located in Sweden.

The findings highlight the potential benefits of the VSM such as being customizable. However, the study also identifies challenges to the VSM as it is missing important parts, such as systems that need to be covered in a digitalization process. This study found it to be a challenge when using VSM as a mapping tool in a complex assembly process and because of that could not identify any potential opportunities or deficiencies regarding the digitalization.

The study also comes with suggestions for further research to explore contextual factors, develop implementation frameworks and investigate the long-term effects and sustainability of this integrated approach.
