Usually, they all work together. A road leads to a mine, for example, but the whole program should have some predetermined steps, which could be established through the history of how one goes through all these projects to get to the end. They all follow different paths, and they reach obstacles, and each time they reach an obstacle they step back and take another run at it—maybe in the same direction or another direction—but overall they probably all go through the same procedures, but with different paths and dealing with different people. Each time there's a new group of people there, of course, it's a whole new program again.
