TAKT DEFINITIONS

Definitions

Below are some definitions for Takt terminology:

 

• Taktzeit: German for baton, beat, or rhythm
   

• Takt (in Construction Takt Planning):  The individual cell representing the intersection of time and space.  This can be empty or include a Takt wagon with process information.  It is the basic unit of a Takt plan.
   

• Takt Plan: The strategic and logistical visual plan that shows the Takt trains in relationship to each other per the specified Takt time with columns of time and rows of Takt zones (geographical location) or general sequences.
   

• Takt Control: A tactical system of holding the dates, stabilizing procurement, limiting work in process, and finishing as you go.  It is the process of using the execution plan within the Takt plan that is constantly evolving and making short-cycled adjustments of the Takt plan to increase flow and improve the execution of the work. Typically, Takt planning takes 20% of the time in development, and the remaining 80% is spent in Takt control.
   

• Takt Phase: The grouping of Takt trains by zones that compile to make up similar types of scope, e.g., structural, rough-in, and exteriors. Takt time and throughput time are specific to Takt phases.
   

• Takt Zone: A production area that is determined by its repeatability and ability to fit into a rhythm with other areas to balance the overall production schedule. This is a batch of geographical area that is either increased or decreased to achieve flow.
   

• Takt Train (sequence): A series of wagons in a Takt zone. This is also sometimes called a Takt sequence.
   

• Takt wagons (train cars): One or more work packages or scope(s) of work packaged into a single cell in a Takt train usually shown on Excel, or a Takt when in an application like Takt.ing.
   

• Work Packages: Features of work or scopes within a Takt wagon. If found within the same Takt wagon, they should not constrain or hinder each other in any way. every package belongs to one trade.
   

• Work Steps: The tasks (value adding activities) in the installation process within the work package. For example, if your work package was OH Electrical, then the steps might be conduit runs, light boxes, fire alarm, cable tray, low voltage, etc.
   

• Takt Time: 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.  It is the syncopation or rate of beats such as one might find on a metronome. To expound, Takt time is the duration of the time scale into which the Takt wagons are fit.  If the Takt time is five days, the wagons fit into multiples of that duration.  If a wagon includes the work package of overhead mechanical and that overall duration is fifteen days, and the Takt time is five days, there will be three Takt wagons that say, “Overhead Mechanical” in three-time scales.
