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.

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.

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. 6] "Lecture Note for Introduction to Decision Theory," Itzhak Gilboa, March 6, 2013, [link].

For software development systems like Kanban, which is production line-centric, Litle's Law tells us. λ = average production rate of complete software components. λ = average production rate of complete software components. There are two fundamental assumptions for Little's Law to work in the software development domain".

Here's another trail being ridden by our son at Nationals in 2013. The notion of Control is missed used in software development projects. They have to be estimated in the start. A quick estimate is needed to decide what to do. Estimating on projects is part of the close loop control system. Good question.

The notion that agile development is a free-for-all development of what ever the customer wants to produce next, with the customer identifying the next important thing to develop works just fine for de minimus projects.

Estimation is part of project management. . The most important estimates for the project manager are related to time and cost. . Since it is easier to estimate small tasks, these estimates are often calculated and performed as point estimates, for example, a task will take 3 days. My proposal is don't estimate.

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?
