"At Herman Miller, they average 1,200 'plan-do-check acts'--that is, little proposed changes to the assembly process--ever year. ... A decade ago, an Aeron took more than 600 seconds in total to build. Today, itâ€™s about 340. Meanwhile, safety metrics have improved by a factor of 6. Quality metrics have improved by a factor of 10. A single Aeron takes one fifth of the labor to make that it once did. The actual factory itself is 10 times smaller. Today, Herman Miller is doing far more with the same labor force that was once producing a sum total of five different office chairs. Today, they produce 17, using roughly the same number of people. And all the while, lead times have shrunk from two months to as little as 10 days." "
