Definition: Takt Time

Takt time is the rate at which a producer will produce goods to meet the customer demand. The word originates from the German word for the baton that an orchestra conductor uses to synchronise the rate of orchestra.

It is an input to the production system from the downstream end, i.e. the rate at which the consumers will buy the product after its production is the starting/governing parameter. The whole production system has to be designed and operated in synchronisation with this demand rate.


Let the demand converted to daily basis (D) for a particular model of a car be 100 units/day. Let the daily time available (Td) for production be 8 hours, i.e.

Then, by definition, takt time for the car assembly, Tt =  Td/D = 28800/100 - 288 seconds

Now the allowed time at each stage of the production process will be 288 seconds.

(a) The engine sub-assembly at a particular station shall be completed within 288 seconds.

(b) Since the car will have 2 doors on each side, a front door fitting should be done within 288/2 = 144 seconds.

(c) A door will have glass and trim fitting requiring equal times. Each should thus be don within 144/2=72 seconds

Thus takt time controls rhythm of the whole system so that the production never lags below the system demand.
