Obviously there were blueprints and solid estimates of the materials and labor required to build the thing. This was no Gaudí cathedral. But there was nothing telling someone when things would be at which stage of construction, just the knowledge that some parts needed to get done in the summer and the whole thing needed to be ready for occupancy on May 1.

I think the story of the submarine/Polaris missile was more interesting. They produced the plan and basically ignored it, and the PERT planning exercise has subsequently been cargo-culted for years.
