Misunderstanding Making Decisions in the Presence of Uncertainty

Herding Cats

What happens if you shift focus from "accurate estimation" to "reliably shipping by a date"? . If your project has no uncertainty, there is no need to estimate. All estimates have precision and accuracy. Deciding how much precision and accuracy is needed for a credible estimate is critical to the success of that decision.

Cone of Uncertainty Bibliography

Herding Cats

This can be the confidence in the estimate for any variable. But is can be ANY variance for the program, including confidence in the estimates of future performance - cost, schedule, or technical performance. This usually results in a project's actual costs far outrunning the optimistic estimates and creating a large overrun.
