Dreyer could challenge the shell system more directly than a committee

Frederic Dreyer appears to have taken more of a lead in the post-Jutland shell work than the investigating committee. A committee could gather information, but admitting the ammunition problem also implicated the wider naval system that had accepted inadequate trials. Dreyer's confidence made him more willing to conclude that the system was wrong and that he could help fix it. Technical inquiry could drive change when one person had both the authority and responsibility to deliver a remedy on time.
