The primary purpose of software estimation is not to predict a project’s outcome; it is to determine whether a project’s targets are realistic enough to allow the project to be controlled to meet them ? The difficulty of accurate size estimation is compounded especially at the time of inception when very little information is available.

The paper on the Cone of Uncertainty is used by many in the No Estimates community as an example of why estimates are of little use. In this paper, there is data that does not follow the Cone of Uncertainty, in that the uncertainty of the estimates does not reduce as the project proceeds. 37–48, 2007. . Wallshein, Ph.D.

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.

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.

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. .
