Merging Diagrams

You can combine multiple Ishikawa diagrams into a master diagram by using the merge operation. To merge a stored diagram into the current diagram, proceed as follows:

• Select File Merge.

• Specify the name of a SAS data set that contains a saved Ishikawa diagram.

Another way to combine diagrams is to open separate ISHIKAWA windows for each sub-diagram then copy them into the master diagram. To copy all or part of an Ishikawa diagram from one window to another, do the following:

• Move the cursor over the head of the arrow.

• Activate the popup menu using the right mouse button.

• Select Copy.

• Position the cursor slightly to one side of the new attachment point and click (just as though you are adding a new arrow).

Example

Suppose you want to create the following diagram by combining information from diagrams already created by each of the major service areas (Pre-Flight, In-Flight, and Post-Flight) and stored in different SAS data sets:

Figure 8.52 A Completed Master Diagram

First, use the ISHIKAWA environment to create the trunk for the new master diagram.

Figure 8.53 Starting a Master Diagram

Select File Merge from the command bar to open the File Requestor dialog.

Figure 8.54 Member Selector

Specify the name of the data set for Pre-flight services and press Open.

Now click on a point along the trunk where this sub-diagram is to attach.

To complete the diagram, repeat the process for the remaining branches.
