I don’t know if I agree with the author’s methodology (insertions + deletions seems like a weird choice for the numerator), but moreover, a big “work vs. final output” ratio doesn’t explain why estimation is so notoriously difficult.
- andrey_utkin 8y agoPerhaps my explanation isn't perfect, but... Maybe in part because it is unthinkable for any "grown-up", "responsible", "engaged" estimator in charge of the project to put in 10x churn into the estimation of resources they request from their management? If you claim you would do that, imagine yourself justifying it to your manager, and then to senior management to which your manager drags you afterwards.
- baddox 8y agoWell, if tasks are taking 10x what you estimated to your manager, your manager is probably already a bit upset.
