We call this Slacker Index—the time required to get a part divided by the time required to get from the the supply chain.
As one example, inertial welding a turbine shaft takes ~minutes. Standard supply base quoted us 88 weeks—Slacker Index well over 100,000.
This creates costs and delays. For example, an engine component that takes ~3 days across a handful of processes, takes 9 months to obtain—because the part spends more time on trucks than on machines, winding its way back and forth between baby factories.
