The Metric Law of 90s

Thanks to Bruce F. Webster, who reminded me of this hoary old saying:
The first 90 percent of a development project takes 90 percent of the schedule.

The remaining 10 percent of the project takes the other 90 percent of the schedule.

Note (15 April 2010) - discovered this is also known as the Ninety-ninety Rule
