Guess i got a blackout bingo on this one. Oof.

Do people not know how bingo cards work anymore?

So what's the actual error margin for estimating feature implementation time? It's going to be nearly the whole thing, right?

[–] [email protected] 3 points 2 months ago (1 children)

Wildly depends on the complexity of the feature. If it only takes 4 hours to implement, you might have good enough of an idea what needs to be done that you can estimate it with 1-hour-precision. That is, if you're only doing things that you've done in a similar form before.

If the feature takes two weeks to implement, there's so many steps involved in accomplishing that, that there's a high chance for one of the steps to explode in complexity. Then you might be working on it for six weeks.

But yeah, I also double any estimate that I'm feeling, because reality shows that that ends up being more accurate, since I likely won't have all complexity in mind, so in some sense my baseline assumed error is already 100%.

Hmm, so kinda O(n^1.5^) scaling? (Of the ratio between definitely required time and possibly required time, anyway, since a -110% error wouldn't make sense)

Really not sure an estimate for algorithmic complexity is the right way to specify this. 😅
But if your supposed input unit is days, then I guess, yeah, that kind of works out.
