Possibility of plane unable to take off at the scheduled time but holding on the runway to make the next available slot.
The problem with cutting some things out is that, even though it might not be utilized 95% of the time, that 5% when you need it, you really need it.
Similar to the backup generator for your data center and justifying it along with the maintenance and tests that go along with it to your boss.
My worry with the direction that engineering is moving, lean, is that we are reducing our safeties below a good level. I see the philosophy moving to other areas, such as finance, creating a race to the bottoms where everyone is leveraged as much as possible. Then when a crisis hits, everyone is unable to survive and we have to turn to government bailouts.
Lean philosophy has recently been targeting healthcare, as a way to reduce cost and reduce adverse outcome while improving quality. While I do think this is important, looking at what is going on in the middle of a pandemic. Is a contributing factor of hospitals running out of masks and ventilators due to lean inventory management practices?
I read a lot a about food wast and how we over produce, it seems logical that there will be a push for lean practices there as well. I could see it being made as a strategy to reduce the amount of CO2 as well as farm land. But conversely, with climate change and the risk of crop failure, is that a good idea?
