When it is mentioned project management is a control system many in the agile world whince. But in fact project is a control system, a closed loop control system. Here's how it works. We have a goal, a target, some... Continue reading

Obvious not every decision we make is based on mathematics, but when we're spending money, especially other people's money, we'd better have so good reason to do so. Some reason other than gut feel for any sigifican value at risk.... Continue reading

The presentation Dealing with Estimation, Uncertainty, Risk, and Commitment: An Outside-In Look at Agility and Risk Management has become a popular message for those suggesting we can make decisions about software development in the absence of estimates. The core issue... Continue reading

Visiting the Montana State Museum of the Rockies this weekend and came across this sign in an exhibit. Now writing software for money is not this kind of science, but it is closely related to engineering and the enablement of... Continue reading

It's become an issue in all domains. Science, Nature, SAciAm all have articles about our inability to think analytically. From Global Warming, the Autism, the GMO's, the fracking, and of course our inability to understand the simple statistical and probabilistic processes that drive project performance. Thanks for the comment

In the agile world there is a common notion that incremental delivery is a desired approach. Many taught rapid release, even multiple releases a day. The question is two fold. Can the customer accept the release into use and the... Continue reading

Warning this is an Opinion Piece. In a conversation this week the quote Insanity is doing everything the same way and expecting a different outcome. Or some variant of that. Attributed to Einstein. As if attributing it to Einstein makes... Continue reading

When there are charts showing an Ideal line or a chart of samples of past performance - say software delivered - in the absence of a baseline for what the performance of the work effort or duration should have been,... Continue reading

I stole this idea of this blog from Stephen Wilson's post of a similar name. And like all good borrows I've added, subtracted, and made some changes, because everything is a remix. I don't know Stephen, but his post is... Continue reading

Project Management is a control system, subject to the theory and practice of control systems. The Project Management Control System provides for the management of systems and processes - cost estimating, work scope structuring and authorization, scheduling, performance measurement, reporting,...

Gentlemen, we have run out of money; now we have to think - Winston Churchill The role of estimating in project and product development is many fold... For product, the cost of development must recouped over the life cycle of... Continue reading

There is a popular notion that agile is bottoms up and tradititional is top down. Neither is actually effective in deliverying value to the customer based on the needd capabilties, time phased to match the business or mission need. The... Continue reading

Why is it hard to think beyond our short term vision? Rapid delivery of incremental value is common sense, no one would object to that - within the ability of the business to absorb this value of course. This is... Continue reading

Igor, Thanks for the response. You're likely right. It's basic business process to estimate things about the future. Sales volume, price of your materials, number of units needed on hand, difficulty of the upcoming work, simple productivity of how fast you can produce outcomes from your effort. More complex might be number of defects in future deliverables, so you can staff the help desk, performance of the release software. But in all cases, estimating cost, schedule, and performance - everything not cost and schedule - is part of the business process of writing software for money.

Since all variables on all projects are random - cost, schedule, and delivered capabilities, in the economics of projects, the chance of being wrong and the Cost of being wrong is the expected opportunity cost. When we write software for... Continue reading

In the estimating discussion there is a popular notion that we can't possibly estimate something we haven't done before. So we have to explore - using the customers money by the way - to discover what we don't know. The... Continue reading

Software development is microeconomics. Microeconomics is about making decisions - choices - based on knowing something about cost, schedule, and techncial impacts from that decision. In the microeconomics paradigm, this information is part of the normal business process. This is... Continue reading

The agile notion of delivering early, delivering often is a wonderful platitude, but ignores the underlying business rhythm for accepting the software features into producitive use by the dynamics of any business or market channel. Here's some examples of business... Continue reading

A common problem in our development of the Program Management Office is getting so caught up in putting out fires. This is Covey's “addiction of the urgent.” In this process we lose the big-picture perspective. This note is about the... Continue reading
