In fact, the more valuable predictive factor was whether or not the combat vehicle had been in a specific area before . It turns out that vehicle commanders, when maneuvering in an uncertain area (i.e. landmarks, routes, and conditions in that area they had never encountered before), tend to keep their engines running for a variety of reasons. That burns fuel.

Seems to me that before a philosophical problem is solved, it becomes a problem in some other field of study. Atomism used to be a philosophical theory. Now that we know how to objectively confirm it, it (or rather, something similar but more accurate) is a scientific theory. Don’t reinvent the world. In almost all cases, someone has already invented the measurement tool you need, and you just need to find it. Here are Hubbard’s tips on secondary research: Identified metrics procedures: Procedures are put in place to measure some variables (e.g. about project progress or external factors) continually.Hubbard then zooms out to a big-picture view of measurement, and recommends the “instinctive Bayesian approach”:

Because initial measurements often tell you quite a lot, and also change the value of continued measurement, Hubbard often aims for spending 10% of the EVPI on a measurement, and sometimes as little as 2% (especially for very large projects). It seems that philosophy (at least, the parts of philosophy that are actively trying to progress) is about trying to take concepts that we have intuitive notions of, and figure out what if anything those concepts actually refer to, until we succeed at this well enough that to study then in more precise ways than, well, philosophy. Just recently the task before me was to implement an object selection feature in an app I'm working on. And in the end I'm going to have to make difficult calls, like how desirable it is for us to have weird chunks of code that look strange by consume noticeably fewer resources. Instead of being overwhelmed by the apparent uncertainty in such a problem, start to ask what things about it you do know.”Hubbard calls this a “mathless” estimation technique because it doesn’t require us to take square roots or calculate standard deviation or anything like that. Moreover, this mathless technique extends beyond the Rule of Five: If we sample 8 items, there is a 99.2% chance that the median of the population falls within the largest and smallest values. If we take the 2nd largest and smallest values (out of 8 total values), we get something close to a 90% CI for the median. Hubbard generalizes the tool with this handy reference table:

How to Measure Anything Quotes by Douglas W. Hubbard - Goodreads How to Measure Anything Quotes by Douglas W. Hubbard - Goodreads

Nothing is impossible to measure. We’ve measured concepts that people thought were immeasurable, like customer/employee satisfaction, brand value and customer experience, reputation risk from a data breach, the chances and impact of a famine, and even how a director or actor impacts the box office performance of a movie. If you think something is immeasurable, it’s because you’re thinking about it the wrong way. If your goal is gauging the effectiveness of this or that approach (agile vs. waterfall? mandated code formatting style or no? single or pair programming? what compensation structure? etc.), then it's slightly less trivial, but you can use some "fuzzy" metrics: for instance, classify "desired things" into categories (feature, bug fix, compatibility fix, etc.), and measure those per unit time.Continues to boldly assert that any perception of “immeasurability” is based on certain popular misconceptions about measurement and measurement methods That might work in an academic setting, but doesn't work in a real-life business setting where you're not going to tie up two programmers (or two teams, more likely) reimplementing the same stuff just to satisfy your curiosity.

In a business case, the economic value of measuring a variable is usually inversely proportional to how much measurement attention it usually gets. However, I was initially a bit confused by the section on EVPI. I think it is important, but it could be a lot clearer. When you’re uncertain about a decision, this means there’s a chance you’ll make a non-optimal choice. The cost of a “wrong” decision is the difference between the wrong choice and the choice you would have made with perfect information. But it’s too costly to acquire perfect information, so instead we’d like to know which decision-relevant variables are the most valuable to measure more precisely, so we can decide which measurements to make. Measurement: A quantitatively expressed reduction of uncertainty based on one or more observations.”And of course programming is diverse enough to encompass a wide variety of needs and skillsets. Say, programmer A is great at writing small self-contained useful libraries, programmer B has the ability to refactor a mess of spaghetti code into something that's clear and coherent, programmer C writes weird chunks of code that look strange but consume noticeably less resources, programmer D is a wizard at databases, programmer E is clueless about databases but really groks Windows GUI APIs, etc. etc. How are you going to compare their productivity? The second form of the question is useful because the answer is often more straightforward and it leads to the answer to the other question. It also forces us to think about the likelihood of different observations given a particular hypothesis and what that means for interpreting an observation.
