On May 25, 1961, President John F. Kennedy announced there would be a man on the moon by the end of the decade. That goal was achieved on July 20, 1969. The complexity of that task must have been huge and yet one giant leap happened on time; in fact six months earlier than thought.
Fifty years on, the memory might lead you to believe that one giant leap happened. It didn't. There were thousands, millions, of little leaps that all culminated in the big one.
After all, Apollo 8 got within 60 miles of the moon surface, so the bulk of Apollo 11 was really only a copy of what had gone before; the "new stuff" was only in the last few steps. A very memorable bit, though.
However, that wasn't Apollo 8's original mission. Instead of going to, and orbiting, the moon, they should have stayed in earth orbit, and tested docking with a lunar module.
Unfortunately, the lunar module wasn't ready in time (lots of unexpected faults cropped up), and NASA had to juggle around the various Apollo missions in order to keep to the end-1969 deadline. Apollo 8's mission was a newly-invented one to test a command module without a lunar module, and to test launch of a fully lunar-capable mission by Saturn V. Apollo 9 ended up testing the LM in earth orbit.
Meanwhile, NASA didn't have faith in the Saturn V for the launch of Apollo 8 - which would be its first use in manned flight (Apollo 7 used a different Saturn model for Earth orbit only). Problems shown up in unmanned Apollo 6, severe oscillation and engine shutdowns, were still being figured out and fixed in the couple of months before launch, and were being tested only 3 days beforehand.
NASA agreed to the changes to Apollo 8, but chose not to tell the public at first. At least not until Apollo 7 was complete. I guess keeping the public up-to-date with the latest project shuffles wasn't foremost in their minds. Keeping the end-deadline, within budget, was firmly in that position.
In those regards, Apollo make for a great example of adaptation to cope with individual problems, just like we see in the FTTC programme. When problems are encountered at any one location, the manpower is redirected into something else while the problem gets sorted out at leisure. The glorious end goal, though, doesn't seem to get delayed.
In fact, the commercial deployment hits its targets 2 years ahead of the original schedule. I see hints that the BDUK one may be early too; work will still be going on, but the 90% coverage target looks likely to be hit.
It seems that the Apollo programme provides a perfect example of how the FTTC programme needs to behave.
