The planned uncertainty not only needs to decrease over time passing, but this reduction diminishes any impacts of risk on the decision-making processes. Seems there is still some confusion (intentional or accidental) about the Cone of Uncertainty and its purpose and its use in software development. 37-48, 2007.

This quote demonstrates a lack of understanding of making decisions in the presence of uncertainty and the processes and events that create uncertainty. There is naturally occurring variability from uncontrolled processes. The risk is created when we have not accounted for this natural variances in our management plan for the project.

Root Cause is the fundamental initiating cause on a causal chain leading to a failure of a process which results in a recurrence of the problem. Root Cause Analysis is a systematic documented approach to arrive at the true Root Cause of the process problem. Gano, Atlas Books, 2007. What Are Problem Causes of Software Projects?

The uncertainty is always there, it doesn't go away with specific actions in specific domains, or with the use of any tools, processes, or practices. The paradigm of using past performance to update the estimates and risks to the project fits into a paradigm of the Cone of Uncertainty. We need a formal risk management process.

In a recent exchange in social media, it was clear the notion of risk and the sources of risk, the consequences or risks and managing in the presence of risk was in very unclear, when it was conjectured , we can simply slice the work into small bits and REDUCE risk. . This is good, but it doesn't reduce risk.

So start here to build your academic foundation, that can be put to work to build a foundation of validated experience of making estimates in the presence of uncertainty and protect yourself from fallacious claims that estimates are a waste, not needed, and produce bad resulting in the decision making process for those paying you to produce value.
