Risk assessment tool output example. Critical hole parameter values (hole perimeter, area and width in millimetres) are entered in the areas inside the green boxes. Other values are calculated by the spreadsheet from the algorithms described in the text. Net diagram at the upper right is an aid showing locations of each area colour-coded to the data entry and algorithm results display area. Below the net diagram, total entry risk is repeated from the bottom line of the display area. Pie chart at lower right diagrammatically apportions entry risk according to each Functional Area. Values entered in this example correspond to scenario described in the text
