This is one of the more interesting blogs I have read in a long time.   This is from a cofounder of a company called Monitor110 that eventually went under:

According to the post, the seven deadline sins are:

1. The lack of a single, “the buck stops here” leader until too late in the game
2. No separation between the technology organization and the product organization
3. Too much PR, too early
4. Too much money
5. Not close enough to the customer
6. Slow to adapt to market reality
7. Disagreement on strategy both within the Company and with the Board
