Yet whenever I've seen this attempted in practice it's failed miserably. It sounded good when I first heard it, but now I treat it as cargo cult nonsense. Maybe it works but
nobody does it right?
A point is a different size for everyone, but a day is a universal (ok technically global) unit.
We deal in time all the time, we know how long an hour is, a day, a week. We can remember "I did something like this before, it took me 2 weeks", not "it took me 13 points".
No manager can predictably translate story points into days, which they need in order to pitch to customers and manage their budgets.
The first thing I ask when I have to estimate in SP is "how many hours is 1SP?" and after a few minutes of the usual back-and-forth, whoever has to actually use these damn estimates always says something like "I treat 1SP as half a day". Bingo, now I can give you a number you can use.
