Why our brain is not built for software engineering. Knowledge work’ refers to tasks that take place mostly in our minds, like predicting scope, setting up plannings, considering consequences of changes to complex systems, working out test cases and estimating complexity. This will affect all estimates and predictions.

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 ? 10 Deadly Sins of Software Estimation , Steve McConnell , Construx, 2002. Steve McConnell.

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.

Then conjecture that NOT estimating will fix that symptom. Then conjecturing (here) that Not Estimating will somehow fix the problem of when you are DSTOP. The supposed evidence in the presentation, that estimating "does not work" starts with the Chaos Report. Principle #3 - Believe the Data, Not The Estimates .
