Nice makeover. Other more minor issues I had with the original: I wish the causes were labeled in situ instead of off to the side, and I noticed the connections from causes to phases maintain their order except for the mechanical/en route connection, presumably to make that line nice and vertical. That seems super minor, but it basically means the information content was sacrificed for the appearance. It's no longer possible to compare the incoming line widths to their overall ranking, which is otherwise represented by the order of the lines.
