Welcome to Lesson 8, Calculate Performance Metrics. You now have a completed Current State Value Stream Map, including process delays and a completed data box. Congratulations, but there is one more step that you need to complete before you get to the exciting phase of identifying opportunities for improvement and creating the Future State Value Stream map. If you are to have an idea of the potential improvement in this value stream, and be able to justify the effort and expense that will be needed to improve it, you need to have some data. You will use the current state value stream map to set the baseline measurements, and once you have created the future state you’ll have some numbers to compare to. Follow along as we calculate performance metrics on the current state value stream map.
