While this doesn't answer your question I would recommend "Lost Victories by Erich von Manstein" as he has a little bit to say on the differences between Hitlers thinking and that of the OKH and his belief that the lack of a unified strategy between the two groups that ultimately lead to failure.
On 6 September 1940, Colonel-General Franz Halder, Chief of Staff of the Army, directed the preparation of plans which were ready by late November, including war games indicating the limits of the forces and logistics needed to support such a massive operation. In early December, Halder discussed the plan with Hitler, who refused to decide whether the basic objective should be Moscow or Leningrad and the Ukraine. This lack of strategic direction haunted the operation, but Halder and OKH (Oberkommando des Heeres, the Army High Command) were confident that Russia could be defeated.
Barbarossa was planned as a ten-week campaign that would start on 15 May 1941, allowing for many months of favorable weather. But events elsewhere delayed implementation of the plan: the Afrika Korps was dispatched to North Africa (February 1941) and German troops were required in Greece and Crete to assist the weak Italians.
