Value Stream Mapping (VSM) is a tool for depicting the flow of material in a manufacturing process. This study demonstrates that value stream mapping can also be applied to the movement and processing of information in Infra structure projects. Currently it takes about 40 days to cast a single slab. The value stream map shows that 7 days of this time consists of non-value added activity such as backlogs and waiting. Using Lean tools both value-added and non-value added activities on the value stream map can be identified. The future state map shows how the process might be improved after changes are made to the process. The challenge lies in organizing the information in the VSM to remove or reduce the non-value added steps. There are some distinct differences between the office processes and manufacturing processes. Unlike production systems, information flows can be loosely structured and use informal scheduling, making it difficult to identify and map their values streams. However, companies can apply value stream mapping tool to office processes in the same way they use it in manufacturing.
