The following is a partial listing of the SAS data set used to create the Ishikawa diagram shown in FigureĀ 8.15:
data ishplane; length _text1_ _text2_ _text3_ $ 40 _side_ $ 1; input _level_ _text1_ & _text2_ & _text3_ & _relpos_ _side_; datalines; 0 Quality Air Travel Service -1.00 . 1 Pre-Flight Service . . 0.26 T 2 Competitive fares . 0.68 R 2 Convenient departure times . 0.18 R 2 Quick ticketing . 0.43 R 2 Frequent flier courtesies . 0.81 L 1 In-Flight Service . . 0.61 B 2 Prompt departures . 0.21 R 2 Comfortable seating . 0.35 L ;
Note the structure of this data set:
The trunk (always the first observation) has a _LEVEL_ value of zero.
All subsequent observations for which _LEVEL_ is equal to one are branches that emerge from the trunk.
Observations 4 and 5 are both leaves that emerge from the preceding stem (observation 3).
Likewise, leaves 7 and 8 emerge from the preceding stem (observation 6).
You can use this data set as a way of extracting text and notepad information from the diagram.
