German machinery was capable but painfully individual

How bad was German warship machinery in the Second World War?

It could be effective, but poor standardization made every plant unusually individual, difficult to train for, and dependent on experienced crews.

The machinery is not dismissed as inherently bad; its problem was the balance between technical optimization and repeatable operation. Each ship, and sometimes each engine within a ship, developed its own settings and handling requirements. American crews examining Prinz Eugen found that class manuals were insufficient and had to recall German personnel who knew the installation's individual adjustments. The example shows why standardization and quality control can matter more to fleet readiness than extracting the last increment of performance from every plant.
