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.

Some feel that the cone does not provide any value for the work they do and does not match the reducing uncertainty in their estimates. First, the Cone of Uncertainty is a Principle used to define the needed reduction in the variances of estimates on Programs. Remember Risk Management is How Adults Manage Projects - Tim Lister.

Let's start with a clear and concise description of the problem of successfully managing projects in the presence of uncertainty: Accurate software cost and schedule estimations are essential for non-trivial software projects. As a software project progresses, more information about the project is known.

The Cone is a project management framework describing the uncertainty aspects of estimates (cost and schedule) and other project attributes (cost, schedule, and technical performance parameters). The BLUE bars are the probabilistic ranges of the current estimate date.

Of late, Cone of Uncertainty has become the mantra of No Estimates advocates claiming that data is needed BEFORE the Cone is of any use. This fallacy comes from a collection of data that did not follow the needed and planned reduction of uncertainty for the cost estimates of a set of software development projects. .
