Takt Time Calculation

A company of engines works 5 days a week with 3 shifts a day. Every shift is of 480
minutes. The break for lunch is 30 minutes. In that period of 13 weeks the customer's
request is 4768 engines.
Calculate the Takt Time in the period.

, Takt time - multiple items problem 1
A company of engines works every day with 2 shifts a day. Every shift is of 8 h .
3 products are manufactured, with different demands.

Adapt the Takt Time calculation to allow producing all these products together in package runs
(= combined runs of all products together).


1) Calculate available labour time
• Time per shift 8h
• 2 shifts
• available labour time: 8 x 2 = 16 h
available labour time: 480’ x 2 = 960

2) Customer Demand : 20 days per month
Demand / month Demand / day
A 12000 600
B 4000 200
C 4000 200
Total 20000 1000


3) Calculate cycle time per product as if it received all available labour time

Item day production cycle time (in min)
A 600 1.6
B 200 4.8
C 200 4.8

4) Determine Least Common Multiple
LCM 4.8



5 ) Determine content of 1 package or sequence
