I just came back from a lunch; a coworker brought up an interesting project analogy:
"I was told that this was a simple project that needed to be done, and should not take any longer than a few days. Unfortunately, it was a bigger task than envisioned so more resources were put into it, which stretched everything out, but at this point, we were committed. Now, someone is leaving. It's like the VietnamWar."
So, to begin the classification (actually, I laughed for a bit. I would have laughed harder had this not been so sad...)
