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.

Estimation is pretentious rationalism, where rationalism does not serve us well (extremistan)(sic) Take only risks you can survive. These estimates can not the ultimate truth since the underlying processes that create the uncertainties (aleatory and epistemic) are stochastic in nature - stationary or nonstationary. The Fallacy.

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.

Of course, all three of these are operating in the presence of uncertainty and therefore require estimates to be made. Estimates of the aleatory and epistemic uncertainties that create risk to the delivered Value need to be handled. All three pieces of information are needed.

The conjecture that we can make decisions in the presence of uncertainty without estimating the impacts of those decisions is without any principles that can be tested beyond personal anecdotes of I know people who spend other peoples money without providing estimates. This list starts with the earliest posts, beginning in 2009. .

There are two kinds of uncertainty on all projects, no matter the domain, including software development projects. The process of making a decision involves three elements: values, alternatives, and facts (Buede, 2009). [1]. The Notion of Enterprise Software Development. Quote of the Day.

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 beginning of a project, comparatively little is known about the product or work results, and so estimates are subject to large uncertainty.

And please take note that we have resources in here, we have estimated work, we have duration, we have some completed tasks. But what we have here is the estimated at completion, estimated costs work performed, baseline costs work performed, and some graphs that actually dive deeper in the indicators that we have as Earned Value managers.

I believe Agile software development is more than ready to use new forecasting techniques to express uncertainy to narrow their decision-making process. These new forecasting techniques are not based on estimations but historical data, thus saving time on the part of developers to focus on what they do best.

Estimating is a learned skill, used for any purpose from every-day life to management of projects. When I left for the airport this morning to catch my flight to a customer site I estimated, given the conditions, how much time I need to get to my favorite parking spot at DIA. So when you hear we can't estimate you'll know better.
