Changing the Bureau of Ordnance's leadership culture

Should the prewar Bureau of Ordnance be replaced by a Royal Navy-style organization?

No; its structure was workable, but leadership captured by a self-confident faction needed replacement and testing had to welcome evidence of failure.

Alex considers the Bureau of Ordnance's structure usable and attributes the problem to a faction unwilling to hear criticism. The British Air Ministry provides a comparison for an organization becoming identified with one group's assumptions. A leader can maintain confidence while still checking reports that challenge an existing decision. Alternative ideas can then be adopted and resources moved toward them. The answer favors changing that institutional behavior over abolishing the bureau.
