There’s often a logistic curve for success probabilities, you know? The distances are measured in multiplicative odds, not additive percentage points. You can’t take a project like this and assume that by putting in some more hard work, you can increase the absolute chance of success by 10%. More like, the odds of this project’s failure versus success start out as 1,000,000:1, and if we’re very polite and navigate around Mr. Topaz’s sense that he is higher-status than us and manage to explain a few tips to him without ever sounding like we think we know something he doesn’t, we can quintuple his chances of success and send the odds to 200,000:1. Which is to say that in the world of percentage points, the odds go from 0.0% to 0.0%. That’s one way to look at the “law of continued failure”.
If you had the kind of project where the fundamentals implied, say, a 15% chance of success, you’d then be on the right part of the logistic curve, and in that case it could make a lot of sense to hunt for ways to bump that up to a 30% or 80% chance.
