Start with the problem
John is most valuable when the answer is not obvious, the cost of failure is real, and someone must understand the whole system before changing one part.
A machine, component, or physical system that is failing, unavailable, unsafe, or no longer supported.
A recurring bottleneck, costly workaround, or process failure that has resisted ordinary fixes.
A production, material-handling, water, biomass, or infrastructure problem requiring practical field experience.
A complex land, fuel, recovery, or community challenge that must be understood as one connected system.
