Death March Redux - Critical Chain Influence -- Edward Yourdon is revising his book, Death March. I'm intrigued and encouraged by the description of Chapter 4...
Critical-Chain Estimating Techniques for Death-March Projects. Why it's so important: along with negotiations, effective estimating is one of the key make-or-break activities at the very beginning of a death-march project. In the rare cases where they're allowed to create their own estimate, as the starting point in the negotiations, project managers need more sophisticated and modern -- and they need to be wary of the secretive attempts of individual project team members to build "buffers" into their own individual task estimates. This chapter explains and discusses the critical-chain estimating developed by Eliyahu Goldratt over the past several years.
I only hope that Yourdon has been distracted by Goldratt's notoriety as originator of the basic CCPM approach and is referring not to Eli's arbitrary "cut in half" approach to estimating, but rather to the resource involving solicitation of 2-point range estimates for both durations and iterations that has been developed by actual CCPM practitioners.
