Sammanfattning: The usage of value stream mapping has to a high degree been limited to entrepreneurs in the construction phase, but it might still be possible for the client to use the tool in the planning phase. If so, this opens up for a new efficiency tool to be used by clients, which could enable economical advantages. This study is thus directed towards the investigation of value stream mapping applications by the client, through a case study at the Swedish Transport Administration. The purpose of the study is to limit waste and increase efficiency in the process activity for quality control of time, costs, and content, from descriptions of new investments until they are approved. The study also intends to investigate the possibilities of applying the Lean tool value stream mapping within the planning phase in the role as client. The study is conducted based on a qualitative strategy. Which follows that gathered data is analyzed thoroughly through the stream mapping analysis. The research approach which is applied is based upon a deductive method, which follows out of that theory concerning value stream mapping and Lean makes up the base of the study. Empirical data for the study was gathered by interviews and documents. Interviews were conducted with both a representative from the section for planning and one from the investments section from all ten of the chosen projects. This was done to get two perspectives on how the process had been conducted.  Value stream mapping were conducted by the means of five stages. The first stage concerned the definition of the process. While the second stage was based around the conductions of a current situation mapping, to conduct this, a statistical analysis was required to get the necessary values. The third stage is made up by a future situation mapping, whereby previous mapping was analyzed through a qualitative strategy, whereby waste and Lean from theory were applied. At this stage, some suggestions for improvements that could be directly implemented were produced. The fourth stage was based upon an ideal situation mapping, which was based upon the expectations that the Swedish Transport Administration have for the process for quality control of time, costs, and content. In this stage improvements that are too complicated for immediate implementation were produced. The fifth stage were based upon creating an action plan for implementation of the suggestions for improvement.  The produced suggestions in the study are the following. ·       Strengthened communication. ·       A priority list. ·       Increased transparency. ·       Increased knowledge within the process for quality control of time, costs, and content. ·       Increased flexibility. The study also clearly indicates that value stream mapping can be applied by clients within the planning phase in repetitive processes with product families.
