Did Bismarck Say 'A Bad Plan Well Executed Beats a Good Plan Poorly Executed'?

Otto von Bismarck was one of the most quotable figures in political history, and his genuine quotes are sharp, witty, and distinctly 19th-century in flavor ('Politics is the art of the possible'). This particular quote about plans and execution, however, reads like a modern management consulting slide. Bismarck's actual approach to strategy was far more sophisticated -- he was famous for maintaining multiple options and adapting to circumstances, not for championing 'bad plans.' Similar execution-over-strategy quotes have been attributed to George Patton, Napoleon, and various business leaders. The sentiment itself predates all of them -- variations appear in military writing going back centuries. Its attribution to Bismarck likely reflects the internet-era tendency to attach generic wisdom to famous historical figures to give it more authority.
