What is meant by takt time?
Takt is the German word for the baton that an orchestra conductor uses to regulate the tempo of the music. Takt time may be thought of as a measurable beat time, rate time or heartbeat. In Lean, takt time is the rate at which a finished product needs to be completed in order to meet customer demand.How do you calculate takt time?
The classic calculation for takt time is:- Available Minutes for Production / Required Units of Production = Takt Time.
- 8 hours x 60 minutes = 480 total minutes.
- 480 – 45 = 435.
- 435 available minutes / 50 required units of production = 8.7 minutes (or 522 seconds)
- 435 minutes x 5 days = 2175 total available minutes.
