Abstract
Advancements in the efficient use of inputs, such as land and labor, have been a key driver of per capita income growth throughout history. One method for identifying potential efficiency improvements is lean manufacturing or lean production, a set of tools to assist in the identification and elimination of waste. Lean classifies waste into seven categories: overproduction, transportation, rework/defects, over-processing, motion, inventory, and waiting. Utilizing economic data, one can track the inventory and transportation time along with the flow time (i.e., the amount of time a unit spends in process), which reveals some of the categories of waste. This report identifies and reviews data on manufacturing inventory and flow time along with data on inter-industry interactions. It then develops a method for tracking the flow time of US manufactured products. This method is illustrated for automotive and aircraft manufacturing.Citation
