Basically, Jeff's point is that the classic iron triangle view of Time vs. Resources vs. Functionality (Scope) is inadequate.

Sometimes all three dimensions of the triangle are locked. If you're given three people, four months, and a non-negotiable budget of $300k to build software, then that's what you do. But how is this possible? Something still has to give. There's an unstated fourth ingredient in the iron triangle: quality.

Once you add the fourth ingredient, the triangle metaphor breaks down. Sam Guckenheimer calls it a tetrahedon. But my co-worker Susan has an even better analogy: it's a stool.
