Because it is a unit-by-unit measure, takt time vs. cycle time provides much faster warning that something is taking longer than it should. Total work content time divided by Takt Time will give you the number of staff required to produce the number of products by customer demand. Work content (Wc) represents total operator cycle time or, if multiple operators, the sum of operator cycle times to perform a specific process(es) or sub-process(es). A management approach that examines the constraints that are holding an organization back. Cycle time equals the average time it takes to finish one unit.

And this is the main theorem in the Queuing Theory, which is also known as Little’s Law (It was described by John Little in 1961): The average number of work items in a stable system is equal to their average completion rate, multiplied by their average time in the system. To optimize workflow, resources, and work time, managers measure the durations of many different processes and average times per items. The difference between batch production and mass production.
