Takt is a German word for 'beat' or 'rhythm' and in Lean this is often referred to as the pace at which your business should operate.
The rate at which the customer uses a product, or the pace at which work must be completed in order to meet customer demand. Takt Time is measured by dividing the average available work time by the average rate of customer demand.
For example: If customers order 90 parts per day, and you have 900 available minutes between two shifts, your Takt Time is 10 minutes. A part must be completed every 10 minutes in order to meet Takt Time.
