After the team maps the steps of the current state value stream during value stream mapping, the next two steps are to measure the performance at each step and calculate the activity ratio. Measuring the performance at each step involves collecting data on cycle time, lead time, process time, wait time, defect rate, and other relevant metrics. This helps to identify the sources of waste, delays, and inefficiencies in the value stream. Calculating the activity ratio involves dividing the total process time by the total lead time and multiplying by 100. This gives the percentage of time that is spent on value-adding activities versus non-value-adding activities. The activity ratio helps to quantify the flow and identify opportunities for improvement
