Takt time is the average time between the start of production of one unit and the start of production of the next, when said starts are established to coincide with the rate of customer demand. For example, if we consider that a customer needs 10 units per week of a certain product, a 40-hour work week and that the flow of work will be constant through the production line, the average time between the start of production of each unit should be 4 hours (in fact it should be less than that because certain interruptions such as machine downtime and scheduled employee breaks must be taken into account). In this way, the production performance of 10 units per week that the client needs would be achieved.
It is common to mistakenly consider that Takt time refers to the time it takes to produce the product. In fact, Takt Time simply reflects the production cycle needed to match demand. In the previous example, it does not matter if the time to create the product is 4 minutes or 4 years, the Takt time should be 4 hours. If a process or a production line is unable to produce at the rate established by the Takt time, it will be necessary to rectify the speed of demand, the resources to be applied or redesign the production process.
Etymology
Takt Time is a term adapted from the Japanese word takutotaimu (), which in turn is adapted from the German Taktzeit, whose meaning is "time interval." The word was introduced by German engineers in the 1930s.[1].
Definition
Considering that a product is manufactured at the rate of one unit for each established amount of time; that this production is carried out in a constant cycle; and that this cycle develops during the available work time on a production line, the Takt time is the amount of time that must elapse between the completion of two consecutive units in order to satisfy the established demand.
Takt Time can be determined with the formula:
in which:.
T=Takt Time, or work time between two consecutive units.
Ta = net time available for work, or work time per period.
D= demand (from the customer), or units required per period.
The net time available is the amount of time established for the work to be done. This excludes rest breaks and any prearranged stops such as scheduled maintenance, instruction breaks, etc.

Takt Time can be determined with the formula:
In reality, operators and machinery cannot maintain 100% efficiency as there will inevitably be unscheduled breaks. Therefore, certain margins must be considered due to these pauses and the production line must take them into account when being configured. Consequently, the production cycle must be slightly faster to be able to absorb these hypothetical unscheduled pauses.
On the other hand, the Takt time must be adjusted according to the requirements within the company. For example, if a company department supplies parts to several production lines, it is common to use similar Takt Times on all lines to align with the previous station's workflow. Customer demand can be satisfied by adjusting daily work time, reducing production cycles on machines,...
Implementation
Takt time is a theoretical estimate to be applied in a production environment. It is used in industry (casting, drilling, or preparing a job for another task), control tasks (component testing or machinery adjustment), or in administration (standard responses to queries or call center operations). However, its most common use is in production lines or assembly lines in which the product is moved along the different stations that make up each line or assembly line, in each of which a series of predefined tasks are performed.
Once a Takt System has been implemented this brings a number of benefits:
