Requirements Consistency Overview

Checks consistency of requirements.

Identify requirement links with missing documents

Ensure that requirements link to existing documents.

Description

You used the Requirements Management Interface (RMI) to associate a design requirements document with a part of your model design and the interface cannot find the specified document.

Results and Recommended Actions

Condition	Recommended Action
The requirements document associated with a part of your model design is not accessible at the specified location.	Open the Requirements dialog box and correct the pathname of the requirements document or move the document to the specified location.

Identify requirement links that specify invalid locations within documents

Ensure that requirements link to valid locations (e.g., bookmarks, line numbers, anchors) within documents.

Description

You used the Requirements Management Interface (RMI) to associate a location in a design requirements document (a bookmark, line number, or anchor) with a part of your model design and the interface cannot find the specified location in the specified document.

Results and Recommended Actions

Condition	Recommended Action
The location in the requirements document associated with a part of your model design is not accessible.	Open the Requirements dialog box and correct the location reference within the requirements document.

Identify selection-based links having descriptions that do not match their requirements document text

Ensure that descriptions of selection-based links use the same text found in their requirements documents.

Description

You used selection-based linking of the Requirements Management Interface (RMI) to label requirements in the model's Requirements menu with text that appears in the corresponding requirements document. This check helps you manage traceability by identifying requirement descriptions in the menu that are not synchronized with text in the documents.

Results and Recommended Actions

Condition	Recommended Action
Selection-based links have descriptions that differ from their corresponding selections in the requirements documents.	If the difference reflects a change in the requirements document, click the link in the Model Advisor results to replace the current description in the selection-based link with the text from the requirements document (the external description). Alternatively, you can right click the object in the model window, select Edit/Add Links from the Requirements menu, and use the Requirements dialog box that appears to synchronize the text.

Condition

Recommended Action

Selection-based links have descriptions that differ from their corresponding selections in the requirements documents.

If the difference reflects a change in the requirements document, click the link in the Model Advisor results to replace the current description in the selection-based link with the text from the requirements document (the external description). Alternatively, you can right click the object in the model window, select Edit/Add Links from the Requirements menu, and use the Requirements dialog box that appears to synchronize the text.

Identify requirement links with inconsistent path types and preferences

Check that requirement paths are of the type selected in the preferences.

Description

You are using the Requirements Management Interface (RMI) and the paths specifying the location of your requirements documents differ from the file reference type set as your preference.

Results and Recommended Actions

Condition	Recommended Action
The paths indicating the location of requirements documents use a file reference type that differs from the preferences specified in the Selection-based linking dialog.	Change the preferred document file reference type or the specified paths by doing one of the following: Click Fix to change the current path to the valid path. Update the preference in the Selection-based linking dialog. In the model window, select Tools > Requirements > Link settings and change the value for theDocument file reference option.

Condition

Recommended Action

The paths indicating the location of requirements documents use a file reference type that differs from the preferences specified in the Selection-based linking dialog.

Change the preferred document file reference type or the specified paths by doing one of the following:

Click Fix to change the current path to the valid path.
Update the preference in the Selection-based linking dialog. In the model window, select Tools > Requirements > Link settings and change the value for theDocument file reference option.
