在这一行动成功的核心是其周密的规划和学说，引导它是启发和个性化的一个人：Dwight D. Eisenhower。虽然这是一个联合的盟军努力，从计划到执行的各个阶段，这是艾森豪威尔的愿景，最终推动了运动。作为盟军最高指挥官，艾森豪威尔是最终负责霸王行动的所有阶段，包括执行相关决策，物流和空中力量。在其执行，艾森豪威尔设想除了胜利。他体现了他的军队必须相信胜利不仅是可能的精神，而且这是他们唯一的选择。他告诉他的官员，“这项行动没有计划与任何替代品。这一行动被计划为胜利，这就是它的方式。我们要去那里，我们把我们的一切投入到它，我们将使它成功。“（5）没有计划B，也没有任何计划失败。艾森豪威尔对他的部队强调说，计划到位是没有条件的，不依赖于环境。计划到位是所有给他们，他们最好不要找借口。鉴于此前宣称的观点学说是由领导和他们在同一个原则下，采用霸王行动通过艾森豪威尔是一个决心，周密的计划和一个整体的说法流传下来的领导，任何短期的胜利是不可接受的。
At the heart of the success of this operation was its careful planning and the doctrine established to guide it was inspired and personalized in one man: Dwight D. Eisenhower. While it was a combined Allied effort in all phases of the operation from planning to execution, it was Eisenhower’s vision that ultimately drove the campaign. As Supreme Allied Commander, Eisenhower was ultimately responsible for all phases of Operation OVERLORD, including decisions related to execution, logistics and airpower. In its execution, Eisenhower envisioned nothing but total victory. He embodied the very spirit that was necessary for his troops to believe that victory was not only possible, but that it was the only option available to them. He told his officers that “This operation is not being planned with any alternatives. This operation is planned as a victory, and that’s the way it’s going to be. We’re going down there, and we’re throwing everything we have into it, and we’re going to make it a success.” There was to be no Plan B and there weren’t any plans for failure. Eisenhower emphatically asserted to his troops that the plans in place were not conditional and were not dependent on circumstances. The plans in place were all that were afforded to them and that they best not look for excuses. Given the previously asserted notion that doctrine is guided by leadership and that they are one in the same, the doctrine employed for Operation OVERLORD through Eisenhower was one of determination, careful planning and an overall assertion handed down by leadership that anything short of victory was unacceptable.
