Why a fast battleship was feasible in 1914

Was a fast battleship still five to ten years away in 1914 because Britain lacked the infrastructure and doctrine?

The counterargument is that Britain already had the dockyards, oil support, and fast-capital-ship doctrine, while small-tube boilers offered a route toward 28 knots.

The Royal Navy already possessed the dockyards, oil-fuel support, and operational interest needed to pursue a fast battleship in 1914. Proposed uses for HMS Tiger exposed the tension between battlecruiser speed and armour protection, since the ship could not remain in some intended fights long enough. Combining Tiger's speed with Queen Elizabeth-class protection therefore appears technologically plausible. Yarrow small-tube boilers supply the proposed engineering route toward roughly 28 knots in a hull slightly longer than a Queen Elizabeth, although the completed design remains hypothetical.
