"The critical path organization of the Apollo Project disclosed some two million tasks that had to be successfully accomplished before the human astronauts were to be returned safely to Spaceship Earth. NASA's Apollo management then put a scientifically and technically competent control group to work to identify all the approximately two million tasks, a million of which required technological performances the design, production, and successful operation of which had never before been undertaken by humans."
Critical Path, R. Buckminster Fuller
