Why German warships inherited the complexity of German tanks

Were German naval vessels as overcomplicated as German tanks in the Second World War?

Yes; layers of committees and individually plausible features produced ships that were slow to build and difficult to keep working.

Complexity generally increased as a project grew and more committees acquired influence. Each proposed feature might be defensible alone, yet the combined design became difficult to build and prone to breakdown. The result was not one obviously foolish choice but an overloaded system whose production and operation suffered from too many good ideas.
