Traceability Matrix view

The Traceability Matrix view displays the trace links in a matrix format. A traceability matrix is used to analyze trace link allocations between two selected structures, for example, a requirement specification and a functional model.

Interface elements

1. Source heading — Displays the name of the structure selected as the source in the Show Traceability Matrix dialog box.

2. Target heading — Displays the name of the structure selected as the target in the Show Traceability Matrix dialog box.

   Note: Source and target structures can be the same to show traceability within the same structure.

3. Total column — Displays the number of trace links for each source element.

4. Total row — Displays the number of trace links for each target element.

5. Leftmost cells in rows — Display the names of source elements.

   Tip: To open a requirement in the MS Word view, right-click the name and choose Open bodytext.

6. Column headings — Display the names of target elements.

   Tip: To open a requirement in the MS Word view, right-click the heading and choose Open bodytext.

7. Status flag cell — Displays one of the following:

   • A solid red fill if one or more source or target elements are not allocated to the other structure.
   • A solid green fill if each source and target element has at least one trace link to the other structure.

8. Body cells — Display the number of trace links between a pair of source and target elements.

Scrolling and locked cells

Note: To keep specific cells visible while you scroll through the Traceability Matrix view, certain rows and columns are locked by default.

For horizontal scrolling, the following cells remain in their current positions:

• Cells in the Total column (the status flag and the number of trace links for individual source elements)
• The leftmost cells in rows (the names of source elements)

For vertical scrolling, the following items remain in their current positions:

• Cells in the Total row (the status flag and the number of trace links for individual target elements)
• Column headings (the names of target elements)

Tip: You can unlock cells by selecting the row or column and pressing Shift+U. To relock the cells, select the row or column and press Shift+F.
