The term takt time is derived from the German word Taktzeit which means beat or pulse. The rate at which you need to produce or manufacture a product to meet the customer requirement is called takt time.
It is an essential tool for efficient flow of goods through the process.
Takt Time = Total available production time / Average Customer demand
Consider the active time only for calculation excluding the breaks, shift changeovers & scheduled maintenance. Production time available & customer demand has to be taken into frames for accurate results. Let us consider the following example.
Let us imagine a company manufacturing printing machine. The company operates 6 days a week at 9 hours per shift including 30 mins lunch break & two 15 mins breaks. The company receives 12 printing machines per week as an average order.
By using the above mentioned formula the total available production time is 8 hours per day which is 480 minutes per day & 2880 minutes per week.
Now the takt time is 2880/12 = 240 minutes to produce one printing machine.
With the given data one can plan the capacity against the customer demand.
There is always a confusion of takt time to lead time & cycle time.
Takt time: The maximum time required to meet the customer demand.
Cycle time: Starts when the actual work begins on the unit and ends when it is ready for delivery.
Lead time: Measures the time elapsed between order and delivery.
For better performance all the above three metrics has to be taken into consideration. Takt time helps to reduce the unevenness of the workflow by optimizing the team’s capacity and also controls overproduction.
Benefits of Takt time
- Helps in establishing a continuous workflow.
- The team’s capacity is optimised to meet the customer demand
- Reduces unevenness & overproduction
