Never attribute to malevolence what is explicable by incompetence. - Robert J Halon When we hear all the bad things that go wrong with projects. The misuse and abuse of data, people, tools, and processes, I get a smile when... Continue reading

There's a never-ending opportunity to learn how to estimate in the presence of uncertainty. Here's some resources for informing that learning process. When you hear that estimates are a waste (we'd rather be coding), estimates are fiction, we're bad at... Continue reading

The presentation "Quantifying the Impact of Agile Practices," Larry MacCherone at the RallyOn 2013 Conference, presents some results on estimating impacts. The chart below shows 4 estimating types, including No Estimates, the sample sizes for each type and the components... Continue reading

The essence of mathematics is to not make simple things complicated, but to make complicated things simple - Stan Gudder This notion that estimating is hard, estimates are a waste because they are always wrong, willfully ignores the basic mathematics... Continue reading

“Would you tell me, please, which way I ought to go from here?” “That depends a good deal on where you want to get to,” said the Cat. “I don’t much care where–” said Alice. “Then it doesn’t matter which... Continue reading

While this quote appears inverted in our self-centered world, the expert has eliminated the nonsensical, naive, amateur, simple minded options and narrowed the choices based principles, practices, and processes of her profession. It is trivially easy to assert I'm exploring... Continue reading

The SAFe Reference Guide is out. The website has most everything you need, but it is hard to use and when printed in simplified mode doesn't contain the embedded pictures. In our local Agile Meetup at Rally, Charles Bradley went... Continue reading

Thanks to Sean Craig's Live Sketch Note for capturing concepts directly from Woody Zuill's talk. This is a good starting point for answering the mail on the notion that decisions can be made in the presence of uncertainty without estimating... Continue reading

Thought interferes with the probability of events, and in the long run therefore, with entropy - David L. Waston (1930) All project work is probabilistic, driven by underlying uncertainties, both reducible and irreducible. Willing an outcome in the presence of... Continue reading

It is probably dangerous to use this theory of information in fields for which it was not designed, but I think the danger will not keep people from using it - J. C. R. Lickider (1950) Related articles Architecture -Center... Continue reading

The mantra of Agile is Trust the team. In some domains, that is an admirable goal. In other domains it's a naïve path to disaster. I work in the latter domain, on mission critical, sometimes national asset programs, but always... Continue reading

The perfect symmetry of the whole apparatus - the wire in the middle, the two phones at the ends and the two gossips at the ends of the telephones - may be very fascinating to a mere mathematician - James... Continue reading

Much of the discussion around project management processes, especially around agile, and most especially around the misconceptions of Estimating as espoused by the #NoEstimates advocates, starts with the misuse of reductive reasons based on single factor analysis. Here's how it... Continue reading
