If it’s due on November 20, then it’s due on November 20. The date won’t move up and the date won’t move back. What’s variable is the scope of the problem—the work itself. But only on the downside. You can’t fix a deadline and then add more work to it. That’s not fair. Our projects can only get smaller over time, not larger. As we progress, we separate the must-haves from the nice-to-haves and toss out the nonessentials.
