Design, doctrine, and ammunition handling at Jutland

Were the British battlecruiser losses at Jutland caused by design failure or doctrinal failure?

Both role and doctrine mattered, but unsafe ammunition handling was decisive in explaining why some ships exploded while Tiger endured comparable hits.

Invincible was not designed to exchange fire with battleships, while Queen Mary's loss cannot be reduced to a single design flaw. The comparison with Tiger highlights ammunition handling: Tiger survived heavy hits while her captain resisted practices intended to increase rate of fire at the expense of safety. Dogger Bank had not exposed the full danger of the faster-firing procedures, which made them easier to preserve into Jutland. Role misuse, command culture, and cordite handling all mattered; armor alone does not explain the losses.
