Value Stream Mapping is a lean tool used for reducing lead time, uncovering waste in production and supply process by identifying non-value-adding steps first and then removing them. A flow diagram of the process and material is drawn which reflects the current state of the operation. The non-value added actions are identified in each step. The waste of time and resources between the steps are also come to light. The process is then analyzed to reduce lead time and simplify the process by taking some necessary actions or applying some lean tools. By reducing waste the proportion of value adding time in the whole process increases and the process throughput production lead time decreases. After that a new, improved, well planned diagram is made. This is called future state map which makes the redesigned process more effective and more efficient.
