Takt time is a German phrase for the baton the conductor uses to set the tempo of an orchestra. In Lean and Six Sigma applications Takt time refers to the rate at which products, information and/or services need to be completed in, to keep up with customer demand. Much like the pulse of a heart rate, Takt time tells us whether we are beating at a healthy rate or we are falling behind.
Takt time is most commonly represented in either seconds, minutes or sometimes hours. For simplicity we will calculate our takt time in minutes. To determine what your average takt time is for your final process you need to divide the total daily amount of working time by the required quantity of products per day.
How to Calculate Takt Time?
If the available time per day is 7.5 hours and the customer would like to receive 350 parts per day, what would the calculated takt time be?
Let’s look at an example. Let’s say that we have 480 minutes of available time in a work day. 60 of those minutes are for lunch and break which leaves us with 420 minutes of available work time. Our next figure will be an assumed 20 working days per month. We will come back to this. Let’s say that in the current month we have 4 different products that total 45,000 pieces that need to be made. Our first step would be:
