« Takt time » is a time reference for producing a part or a finished product as per client’s requirement.
In this way, if each product comes out following an equal time interval to the takt time, the flow is synchronized with the client’s request. It is the best way to understand customer rate of demand.
Takt word originated before industrial revolution and indicated in term of “beat”, “beat triggered” or “rhythm”, Takt time was Initially used by German industries later it was adopted by Toyota as part of TPS (Toyota production system). Using rhythm to maintain flow of production.
Takt Time Details:
Takt time formula is:
Takt time = Available working time in a period / Customer demand in that period
Period can be Shift, day, month etc.
Take an example:
A Ball manufacturing company operates 100 minutes per day. Its customer demand is 25 balls per day. Calculate its takt time:
100/25 = 4 minutes
So, the Ball manufacturing company have the takt time of 4 minutes, meaning it needs to produce a single ball in every 4 minutes.
Takt Time Benefits:
- Key element for JIT (Just in time) -See this item in glossary
- Improves customer satisfaction
- Smooth production planning & reduced interruptions in operations
- Gives the rhythm at which system should operate
- No over production
- In process stock reduced
- System synchronization with client’s demand
- Enable pull scheduling or pull system
- Meeting deadline without rush
- Bottlenecks can be easily identified
- Improves productivity rate at a much higher rate
Difference between TAKT Time, Cycle Time and Lead time:
Lead time: Time needed to meet a customer’s request or time needed from receiving of an order till its fulfillment to the client.
Cycle time: Cycle time is the time needed to complete and operation.
Takt time: utmost limit of time to meet customer demand.
Why Takt time:
Organizations adopting lean manufacturing and just in time, Takt time is an important key element for practicing these methodologies.
Takt time is easy to measure, understand customer rate of demand and monitor. It is an important factor for synchronizing rate of production at each process step.
