The Cone of Uncertainty

I came across a great set of responses to an IEEE Software Article by Ted Little that seemed to question the cone of uncertainty. Among the respondents were Phillipe Kruchten and Steve McConnell. This prompted me on a search for resources about the cone of uncertainty. Here is what I came up with:

The Cone of Uncertainty, letters to the editor in response to Little's article.

Schedule Estimation and uncertainty surrounding the cone of uncertainty, Little's article in the May/June 2006 issue of IEEE Software.

The Cone of Uncertainty described at the Coding Horrors blog

Reducing the cone of uncertainty, an article from the August Newsletter of Pivotal Insights

How much will it cost? Part I - The cone of uncertainty, an article from Vantage Technology Group

The Purpose of Planning, chapter 1 of Mike Cohn's book on Agile Estimating and Planning

Estimation Variance and Governance, by Murray Cantor, from the March 2006 issue of The Rational Edge

Does anyone know of others? I'm particularly interested in anythingavailable online by Barry Boehm and also from Steve McConnell.

You probably already know that, but it's also in the recent steve McConnel's book: Software Estimation. Well as it's already originated by the PMI, it should be able to track it from the source, but I honestly don't know how...
