Takt Time - What is and why use it
Introduction
Takt time derived from the German word Taktzeit, which loosely translates to “rhythmic time” or “keeping a beat”, similar to the ticking of a metronome or the movement of a conductor’s baton. Takt time first was used as a production management tool in the German aircraft industry in the 1930s. It was the interval at which aircraft were moved ahead to the next production station. The concept was widely utilized within Toyota in the 1950s and was in widespread use throughout the Toyota supply base by the late 1960s.
Takt Time Definition
Takt time is the pace of production that aligns production with customer demand, calculated as:
Takt Time = Time Available / Customer Demand in the period
It should be noted that the values must be expressed in the same units of measurement, usually in seconds.
It is the heart beat of a lean organization. It is not a goal to be surpassed, but rather a target for which to aim:
Takt time and Balanced Line
The visual presentation of Takt time is shown on the Line Balance chart.
Line Balancing is a production strategy that involves setting an intended rate of production for required components to be fabricated within a particular time frame. In addition, effective line balancing requires assuring that every line segment's production quota can be met within the time frame using the available production capacity.
Balance the workload of the operators get the following situation:
The requirements are as follows:
