As read in Derek Featherstone’s latest blog entry entitled “I hired Jeff Smith”, dd 2007.02.19:
“80% ready is the new metric I use to decide if it is time to do something. That is based on the following premise:
If you wait until you’re 100% ready, you’ll never do anything.
You will never be 100% ready, but once you’re 80% ready, you’re committed and the rest is details.”
