Q1. How do you calculate takt time
Ans. 
Takt time is calculated by dividing the available production time by the customer demand.
• Calculate the total available production time in a specified period (e.g. 1 day)

• Determine the customer demand for the same period

• Divide the total available production time by the customer demand to get the takt time

• Takt Time = Total Production Time / Customer Demand
