There's another rash of Twitter posters supporting the conjecture that decisions can be made about how to spend other people's money without estimating the impact and outcome of that decision. This is a core premise of #NoEstimates from the Original... Continue reading

The book is an easy text to write critique against. Nealry every paragraph so far has some nonsense ideas, naive concept or personal anecdote that could on;y be applicable to a small group pf coders spending their own money to develop a personal products. For $9 it's good entertainment on what not to do on most anything having to do when spending other people's money. I think I'll syndicate it out in chapters

Every paragraph has some cockamammy idea that is over the reservation in any normal business. Chapter 1 opens with (Carmen’s been asked to work a new project) “Is it twice as big as the Telemark project?” She asked, but her boss didn’t reply. “Five times bigger?” Still no comment. “Ten times bigger?” “Actually, it is a public sector project, so I guess you could say that it’s several orders of magnitude bigger than your Telemark project….” He finally admitted. Several orders of magnitude means 100 to 1,000 times bigger. And Order of Magnitude is 10x, where X is the order of the magnitude. This seems common for #NoEstimates advocates to confuse what this means. Vasco has suggested that not estimating can improve project performance by orders of magnitude - 10’s to 100’s to 1,00’s of times bigger. All of this by the way with no testable evidence, other than anecdotes (unverified anecdotes). “Oh…” Carmen was speechless. This could potentially be the largest software project in the country, and she was being lined up to manage that project. So the boss is giving a project to a manager that is several (I’ll assume 2 or 3 is several) orders of magnitude larger ‒ and a project that is the largest in the country ‒ and it’s a public sector project ‒ spending a sovereign’s money ‒ to a PM that has no experience with this size? This would be unfathomable in any non-trivial domain, where a sovereign issues contracts for software intensive systems, with strict contract performance items in the Statement of work. The example is not only notional, it is not credible. It’s an indication that Vasco has little understanding of how working for a sovereign actually takes place. “And we’ll need to present a bid by the end of next week!” Her boss looked excited. “So get your team on it. We need to close this deal now Carmen; it could change our company’s future! We need to submit our proposal as soon as possible!” Prepare a proposal for the largest project in the country in a week ‒ Preposterous!! I work proposals for Federal Agencies (sovereigns) for software intensive system of systems. Either Vasco has zero experience in this domain, or his readers are clueless about how large complex software system are procured by public sector firms ‒ most likely both. If this is an indicator of how naïve the book content is, this review is going to be short and sweet.

Uncertainty is all around us. In the project world, uncertanty comes in two forms: Aleatory Uncertainty - the naturally occurring variances due to the underlying statistical processes of the project. These can be schedule variances, cost variances, and technical variances... Continue reading
