Have you ever

• misunderstood a customer request?
• ended up delivering a lot more functionality
  than you originally estimated?
• missed a deadline because the customer changed
  the specifications at the last minute?
• found a software defect caused by an incomplete
  change?
• forgotten to notify someone when a change was
  made?
