It’s hard to believe but in 1979, the US Manufacturing workforce peaked at 19.5 million jobs. Since then US Manufacturing jobs have declined by about 40% to 11.7 million jobs with much of the job loss occurring in the last decade. About half the job loss is due to jobs displaced by Chinese manufacturing and much of the rest due to improved labor productivity. Yet with productivity up substantially, the US is still the world’s manufacturing leader producing 19% of the world’s goods compared to China’s 15.6%.
How do we deal with this in the Lean world? We want labor productivity yet this can often mean job losses as fewer people are required to maintain the same output.
Let’s go back to the basics of Lean and remember the principle of “Respect for Humanity”. This is very deep and can have multiple interpretations but in this case it means that improvements in labor productivity must never result in lay-offs or people being let go to “cash out the gains”. Instead Lean views the unused labor as unused capacity to produce more goods and produce more improvement. Rather than overproduce goods (one of the biggest causes of waste), people are used to drive out waste and solve problems resulting in stronger processes. This allows Manufacturing to work with Sales and Marketing to open new markets and launch new products, both of which drive up volume and use up the excess capacity that was generated.
Organizations that do this are on an upward spiral. The more improvement they get, the more people can be freed up to drive more improvement. At each loop, costs go down allowing volume to go up driving a need to use some people to produce the additional goods.
Sometimes this is short term pain for long term gain as it takes time to develop new markets and launch new products but isn’t that just another opportunity to apply Lean?
This all becomes possible if we view Lean as a growth strategy, rather than a cost reduction strategy and we stay true to the basic principles of Lean including “Respect for Humanity”.
