The CoU paradigm defines the needed reduction in uncertainty is some performance metric. This can be the confidence in the estimate for any variable. It can be the needed performance of a measure - Effectiveness, Performance, Key Performance Parameter, or a Technical Performance Measures.

I've seen estimates abused by bad managers, so let's NOT estimate and that will fix the behavior of Bad Managers." While the human behaviors are real and observable, conjecturing that decisions can be made in the presence of uncertainty without estimating the outcome of those decisions, there is no principle to support that conjecture.

There are cost people, scheduling people, risk people, EVM people, engineers, testers, and others on any program. Technical performance is likewise difficult to integrate with either cost or schedule because its units of measure vary with the subject matter.

All making things smaller dos is show that you're late, over budget, and what you're building (Technical Performance Measures) doesn't work faster. But when some statement is made about risk, estimating, performance modeling, or the like - always ask for references. This is good, but it doesn't reduce risk.
