Abstract A continuous, if at times faltering, path of policy and practice in the procurement of British military aircraft is traced through the years up to and during the Second World War. The focus over the latter part of this period is on the development of procedures for the planning of production programmes within the relevant Government departments, and the growing coordination of that with the corresponding evolution of processes in the manufacturing industry. Though repeatedly threatened by constraints at home and world events, this collaboration produced a robust system of production that at its peak in 1944 employed nearly two million people and delivered more than 2,500 aircraft a month to the Services. Woven into this account are some details of planning methods used in the Ministry of Aircraft Production, from a bequest of papers of J V Connolly, made recently to the National Aerospace Library, Farnborough. https://www.aerosociety.com/media/1...r-and-reference-to-james-connolly_2018-09.pdf
I would recommend looking at the career of Wilfred Freeman, an influential RAF officer and the book cited on Wiki is great: Wilfrid Freeman - Wikipedia
