Which metric helps to identify the average time a product takes to move through different production stages?

Utilization metrics assess the extent to which production resources (such as machines and labor) are being used compared to their total capacity. While relevant for measuring efficiency, they do not provide information on the time taken for a product to move through the production stages.

Process velocity metrics refer to the speed at which a process operates, often expressed as the rate of output over time. However, this metric does not specifically measure the average time taken for a product to navigate through various production stages, making it less applicable in this context.

Efficiency metrics evaluate the ratio of output to input in production processes, focusing on how well resources are utilized. Although useful for assessing overall performance, they do not capture the average time a product takes to pass through production stages, which is the primary concern of the question.
