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. Then there is some analysis.

Seems there is still some confusion (intentional or accidental) about the Cone of Uncertainty and its purpose and its use in software development. 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. This letter states.

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.

The Cone of Uncertainty is a framing assumption used to model the needed reduction in some parameter of interest in domains ranging from software development to hurricane forecasting. 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.

And so this is where agile kind of fits in and isn’t just necessarily only for software development. And remember, agile is kind of born out of the need for technical project management or in many cases, software development. But it is clearly not limited to just software. Am I getting the velocity?

The major problem was/is not the idea or concept of ‘project’ in general, but the fact that in a context of software development it typically meant a fixed-price project in which the three elements of the infamous iron triangle of software development (budget+time+scope) were fixed through upfront analysis and design phases.
