One of the key points to the FIST value concept is the idea of restraint. We believe restraint is absolutely essential for any project leader who values completing an effort quickly with the maximum amount of goodness. Lucky for us, this recent article in WIRED magazine highlights just how important restraint really is.
On a related note, it's fantastic to see a major publication acknowledging the value of failure (WIRED's Jan issue is all about failure). We often talk about the importance of failure and how the FIST values increase your chance of an optimal failure - were much is learned and little lost. I highly recommend the issue.
