M4E #22: How to measure Takt Time and Cycle Time?
Unlike other words used in the lean world that have their roots in japanese, takt comes from German taktzeit, a measurement used in music. You can translate it as beat or pulse, matching the rhythm provided by a metronome. However, Takt time is usually confused with Cycle time. The next video from LeanActivity explains the differences between them.
Time for Insights
Neither Takt time, nor Cycle time should be confused with another measurement: Lead time. It refers to the time that passes between the moment an order is placed by the customer and the instant the manufactured good is delivered.
In order to meet customer demand, as told in the video, the Cycle time must always be lower than the Takt time. Be careful when checking this, as this condition must be true for every machine or station involved in the production process. Thus, if only one of the machines has a Cycle time higher than the Takt time you won’t meet customer demand.
Why you should calculate and use Takt time? Short answer: Because it’s an indicator that can be used for continuous improvement. Takt time can be used as a basis to standardize processes and cycle times, maintain continuous production flows, minimize worker overtime or reduce errors and increase product quality.
