Thanks for the read. Came to this from our news issues as well. Fair and Balanced assumes both sides have credible positions on a shared topic. This is not the case for #NoEstimates. There is no principle by which decision can be made in the presence of uncertanty without estimating the outcomes. Same for Climate, Immigration, Voter Fraud, MacroEcon and a raft of other contentious topics. We seem to have lost our critical thinking skills lately. But political debate needs to be "fact based" just like those other topics, and we've lost that ability as well. Here in the US we have many "fact checking" sites, many run by newspaper, but other independent, so there is hope if the populous will read them. BTW your book is in a bibliography for our Agile+EVM guide published by National Defense Industry Association and in another bibliography for "Measureable News" a journal of sorts for the College of Performance Management (www.mycpm./org) which and colleague and I edit.

We hear fair and balanced is a desirable approach to problems. Turns out this is a false balance when the issue under discussion doesn't address an underlying principle. One side can be wrong It is seductive to state we're exploring... Continue reading

The ability to generate reliable cost and schedule estimates is a critical success factor necessary to support business projects. Without this ability, business value is at risk of experiencing cost overruns, missed deadlines, and performance shortfalls—all recurring problems that projects... Continue reading

So you mixed the axis. You seem to be using NE words. I know of no business in my 38 years of development and management of develope that doesn't consider Cost a critical success factor. YMMV.

So the units of measure of the vertical axis are not cost? So the estimates weren't used to establish the budget for the project? So the project wasn't managed to the budget? What are your units of measure for "great?" I counted "words" not pages.

OK, I'll change it to "your projects went over budget." when you say ... While controls and planning are useful, an overly strict focus can result in attempts to solve the wrong goal. Shipping on time, to specifications, and within budget might be meaningless if a competitor is shipping software that has a greater value to the market. In that case, the competitor will win nearly every time, and the prize for “good” project management might be losing market share. Seems you spent 90% of the paper showing 2X overages, Figure 2. I'd consider that a significant impact on ROI for those "desirable features." I guess Landmark considers that success. Why not have all three plus market success? Does shipping late and over budget have any impact on the market acceptance or your balance sheet. You're right I work in a domain where meeting market needs, having a superior product, AND showing up on time and on budget is the basis of success. YMMV
