such that precision is essentially impossible.
Imagine estimating your velocity driving across country. Estimating
to even the nearest mile per hour over each short interval is simply
silly. Tracking our speed over small intervals won't work because of
traffic, weather, and other factors. Keeping track of our overall
speed across country is interesting, but precision would be entirely
wasted: one extra rest stop or a slow waitress at lunch will change
the number substantially.
We find that estimating stories in small proportional integers 1, 2,
3, and counting the points upon completion, is sufficient for most
For a sense of the level of precision that I think is appropriate
for most projects, you might enjoy this article:
Big Visible Charts
It's time to revisit the topic of Big Visible Charts. Display
important project information not in some formal way, not on the
web, not in PowerPoint, but in charts on the wall that no one can
miss. [Updated: Velocity Charts]
There's a difference between righteous anger and just being crabby.
