80% seems far too optimistic. From what I know of projects and development I would think upwards of 90% of all software projects are never shipped. Maybe 95%. Even higher would not surprise me. Maybe this is considered pre-crash or pre-burn by them. Maybe "80% of projects that get publicly acknowledged and are expected to be successful" crash and burn. It must be so much higher.
