As interesting as it is to guess why another waterfall government IT project failed, I'd rather know why we aren't using wheelbarrows with wheels closer to the center. As a guy who has mostly used wheelbarrows for moving concrete, having the wheel support the majority of the load instead of half (or whatever) sounds like a huge advantage.
The Wikipedia article on wheelbarrows suggests "However, the lower carrying surface made the European wheelbarrow clearly more useful for short-haul work." Does that reason really pan out? Can anyone think of any other reasons?
