What is Takt Time? How to Measure Takt Time? Application of Takt Time in Apparel Industry.
Definition of Takt Time
Takt
time is nothing but the allowable time to produce the product at the rate of
customer demand. Many people considered it as cycle time. But it is wrong. Takt
is not cycle time. It is allowable given time from the buyer side to produce
products.
So, anyone has to remember that-
1. Takt Time is not cycle time.
2. It cannon be measured by stopwatch like
time study
3. Takt Time value can change by increasing
production in given shift time.
How to Measure Takt Time?
To measure Takt Time two thing is required. They are-
1. In hand time
2. Demand of customer
In hand time is the lead time of delivery and demand of customer is
how much quantity is required in the given lead time. The formula to determine
the Takt Time is –
Takt Time
= In hand Time/ Demand of Customer
Question: A sewing line runs total of 10 hours. Within this time customer demand is 700
pieces. What is the Takt Time?
Solution:
In hand Time = Shift Duration
= 10 X 60 Minutes (to convert hour to the minute, 60 has been
multiplied)
= 600 Minutes
Demand
of Customer = 700 pieces
So, Takt time = 600 / 700
= 0.86 minute
Answer: Here Takt Time is 0.86 minute. So, need to produce
1 pieces of garments within 0.86 minute.
Application of Takt Time in Apparel Industry
In the above example the Takt Time is 0.86 minute. If per pieces
garment can be produced within that time no problem will come during final
shipment of the garments. But if the product making time is greater than 0.86
minute then total pieces cannot be shipped on time. So, in this situation extra
care have to take. Such as, need to
increase productivity within the given shift time or need to do overtime for
more production.
From the value of Takt Time we get such message and can take
decision before affecting on final shipment.
