Takt Time

Sono a sottoporvi una breve ma corretta spiegazione di cosa sia il Takt Time; per gli appassionati di Lean Organization un argomento che si tratta continuamente ma a cui pochi sanno dare una corretta spiegazione.
Ma voi, come definire la richiesta dei vostri Clienti/Mercato??
Per adesso vediamo con quale ritmo dobbiamo rispondere
Takt time can be defined as the maximum time allowed to produce a product in order to meet demand. Here’s the lowdown on how you can apply it.
It is derived from the German word taktzeit which translates to clock cycle. The pace of production flow would then be set based on this takt time. Product flow is expected to fall within a pace that is less than or equal to the takt time. In a lean manufacturing environment, the pace time is set equal to the takt time. A similar but alternative definition can be found here
How is Takt Time established?
What is Takt Time?
The customers buying rate establishes Takt Time. It’s the rate at which the customer buys your product. It is calculated as the net available production time (the amount of time available for work to be done. This excludes break times and any expected stoppage time) divided by customer demand. It provides the heartbeat of a lean production system.
Improving Takt Time
Takt time isn’t “improved.” Cycle time is improved. Takt time is the amount of time “allowed” to complete a work sequence. Cycle time is what is “required” to complete a work sequence. We can reduce the Cycle Time and the content of the work involved in that Cycle, such as reducing or eliminating waste and non-value added steps, thereby influencing the Takt Time, or overall beat of the line. Specifically, we can do the following:
Reduce Variation
Reduce Idle Time
Reduce set-up time
Reduce or eliminate waste
Better manage constraints
