Cycle time variation

From Wikipedia, the free encyclopedia

Cycle time variation is a metric and philosophy for continuous improvement with the aim of driving down the deviations in the time it takes to produce successive units on a production line.[1] It supports organizations' application of lean manufacturing or lean production by eliminating wasteful expenditure of resources. It is distinguished from some of the more common applications by its different focus of creating a structure for progressively reducing the sources of internal variation that leads to workarounds and disruption causing these wastes to accumulate in the first place. Although it is often used as an indicator of lean progress, its use promotes a structured approach to reducing disruption that impacts efficiency, quality, and value.[2]
