A key aspect in Lean Manufacturing is Waste. In 1937 Taiichi Ohno working in "Toyota Automatic Loom Works" factory stated that the productivity of an American worker was nine times higher than a Japanese worker. In 1945 Ohno found himself thinking about that gap in productivity. He found there was too much waste in Toyota’s processes. His assumption being if the waste could be eliminated then productivity will increase. And this is the moment of the onset of the Toyota Production System.
Subsequently, 7 wastes were identified that are central to the TPS and well identified in the production environments. over-production, waiting, transportation, over-processing, inventory, motion, and defective products. In other than production environments identifying the wastes is a more delicate task. As in 2020, we started to do more work from home and the 4th Industrial Revolution continued to evolve with more and more workers engaged in digital work. Office and IT work are 2 key areas where we look to create more value.
