The ISHIKAWA Procedure
Managing Complexity
A major advantage of the ISHIKAWA environment is that you can quickly organize a highly complex diagram. However, not everyone may be interested in seeing all the details—at least initially.
To increase the level of detail by one level, do the following:
-
Move the cursor to a background area of the window, and use the right mouse button to activate the background popup menu.
-
Select . On some hosts, you can press the > key instead of using the popup menu (as long as you are not editing text).
Each time you select from the background popup menu, the detail increases by one level.
To reverse the process and decrease the level of detail, select from the popup menu, or press the < key.
Example
You are making an online presentation about factors that influence the quality of air travel service. The following diagram presents too many details to be a good starting point for your audience:
Figure 8.45: Highly Detailed Ishikawa Diagram
A better way to begin is by displaying only the trunk and branches.
Figure 8.46: Branch-Level Diagram
Then, at the next stage of your presentation, dynamically foliate the branches with stems, as follows:
Figure 8.47: Increasing the Level of Detail
The amount of detail is increased by one level.
