My rule of thumb is: ((Time Estimated as worst case * 2) * 130%) = close to true most times. I would say it's a normal distribution with a smallish variance.

worst case I can do that in a week ==> (1 Week * 2)*130% = 14days + 4.2days = 18.2 days give or take. Usually pretty accurate.
- ams6110 16y agoHow long as this been your rule? Do you not find that you unconsciously improve your worst case estimates and your buffer for unknowns becomes excessive?
- weaksauce 16y agoIt's been a while. no I find that as a programmer we tend to be overly optimistic on things and do not take into consideration the other things that need to be done. For example, the cost of meetings, underestimating the scope of the problem, and the little snags that eat up time. An example of a little snag is trying to get some library or program that you need to continue installed and configured correctly. This takes more time that you expect it to.
