Fascinating implication for projects with different amounts of risk, expressed as sigma:

So just as an example, if σ = 1.0, then we should give up at 320% of the original estimate. If we follow this policy, then we finish about 88% of all project.

But if σ = 1.4, then we should give up at 72% of the original estimate, and if we do that, we finish only 41% of all projects.

High risk projects should be abandoned at just two-thirds of their expected duration.
