Figure 7.2. The first version of the Preliminary Table List
Using the List of Subjects
Now, create a second version of the Preliminary Table List by merging the list of subjects
(created during the interviews with users and management) with the first version of the
Preliminary Table List (compiled by studying the Preliminary Field List). This new ver-
sion contains a more complete list of tables. Merging the two lists is a three-step process,
which involves resolving duplicate items, resolving items that represent the same subject,
and combining the remaining items together into one list.
Step 1: Resolve Duplicate Items
Start this step by reviewing and cross-checking each item on the list of subjects against
the items on the Preliminary Table List. Your objective here is to identify
duplicate items,
which are items on the list of subjects that already appear on the Preliminary Table List.
You must be very careful how you resolve the duplicate items that you find. Begin by de-
termining whether the items represent
different
subjects, despite the fact that they share the
same name. (Use your interview notes as necessary to help you make your decision.) If
they do represent different subjects, rename each item so that it accurately identifies the
subject it represents and then add both items to the Preliminary Table List; otherwise, de-
termine whether they truly represent the same subject. When you conclude that both items
do represent the same subject, cross out the item on the list of subjects and keep the one
that appears on the Preliminary Table List. Then resume the review until you've examined
