The germans lacked for nothing in either their raw industrial power nor the advanced nature of their designs at the outbreak of war. What wrecked their ability to win was their mismanagement of the resources they commanded. Sticking to designs well past their prime for too long. inadequate forward planning in the lead up to war. overuse of the air force, and a multiplicity of fronts brought about by what was essentially an opportunist war strategy. A poor command structure and virtually no co-operation with allies. Later shortages of resources, fuel, transport (rail capacity), manpower shortages, fragmentation of production programmes all destroyed any chance the germans may have had for even a negotiated surrender.
