Page 56. Ask the project teams to complete and compile a list of all assumptions that have been made in those initial projections then ask them which of these assumptions need to prove true in order for us to realistically expect that these numbers will materialize?. the assumptions on this list should be rank.

In the book
Keep an honest logbook, and design your endings. Since memory weights the peak and the end far above the middle, end things well on purpose — a hard day, a visit, a project — because the ending is what you will actually keep. And write your assumptions down before a decision, so you can check later which ones were true. Gain altitude when you're stuck. When the trees close in, rise above them; step outside your own skin and watch the trouble as a spectator would; and view the wound from the distance of a century, where almost all of it shrinks. — The Instruments (Awareness/Perception/Expectations)
