....that's not an order of magnitude each time
- janto 5y agoa calendar "order of magnitude". I can't think of a better term.
- powersnail 5y agoPerhaps “up a unit of measurement”?
- janto 5y agosounds about right
- bluenose69 5y agoThis is what I was taught: double the estimate, and increase to the next unit. It was mostly as a joke, though. The wise scheme, as has been pointed out, is to adjust predictions during a project. If the task that was initially planned to take a day is routinely taking 2 days (or 2 hours), adjust future plans accordingly. Higher-level managers are sometimes unhappy with this scheme, while middle-level ones value the accuracy of such predictor-corrector schemes. This gets us into a related topic of the depth of management structures, and I think the military scheme (of each person directing a roughly fixed number of persons, so the number of levels is proportional to the log of workforce size) might be worth considering.
- mdp2021 5y agoI would say it is a "superset timeframe".
- umanwizard 5y ago“Order of magnitude” is a colloquial, imprecise term that doesn’t actually mean “exactly ten” (otherwise, people would just say “ten”).
- okamiueru 5y agoIn an engineering context, I would interpret it to be "roughly ten times", because that is what it means. And the same argument,that if they meant something else, would just say "three", or what have you. In this case h-d is 8x, d-w is 5x, w-m is 4x and m-y is 12x. This is after all just unimportant pedantic, but if clear and simple communication is the goal, it probably makes more sense to describe it as the next calendar unit up.
- janto 5y agoFor interest sake, it looks like non-decimal reference values have been used https://en.m.wikipedia.org/wiki/Order_of_magnitude https://en.m.wikipedia.org/wiki/Order_of_magnitude
- flavius29663 5y agoThat is beyond the point, since the OP changed the magnitude with every size. If it was 8x at each iteration, we would've had less pedantic comments here
- janto 5y agoHaving quotation marks around "order of magnitude" sure didn't stop pedantic comments. I'm not sure what can.
- evanb 5y ago> I would interpret it to be "roughly ten times", because that is what it means Only if you work base-10!
- Stratoscope 5y agoIf you're looking for precision when we're estimating, you may be in for a rough time.
