Beatty, staff work, and signalling at Jutland

Did Beatty mainly need a better chief of staff to correct the shortcomings seen at Jutland?

Not simply. He had a substantial staff, but doctrine, signalling responsibilities, and his failure to provide Jellicoe the needed course-and-position information were central problems.

A stronger chief of staff alone would not have solved Beatty's problems. The Fifth Battle Squadron was expected to communicate with Beatty, while Beatty's staff should have passed decisive course and position information to Jellicoe. Cruisers broke protocol because their officers understood the operational danger, whereas Evan-Thomas had been selected partly because he reliably followed orders. Beatty had a flag captain, senior officers, and junior staff as well as Seymour. His weakness was failing to frame information consistently around his superior commander's needs.
