Track Requirements Implementation Progress

View Implementation Status

Open the myAdd project.

openProject("myAdd");

Open the myAddReqs requirement set in the Requirements Editor.

slreq.open("myAddReqs");

Enable the implementation status. In the View section, select Show Requirements > Tabular View, then select Columns > Implementation Status. Ensure that Requirements Toolbox is analyzing functional requirements for implementation links by clicking Refresh.

The empty implementation status bar indicates that the requirements do not have implementation links. View detailed information about the implementation status by pointing to the implementation status bar for the requirement set. The tooltip indicates that the requirements are not implemented.

In Link Requirements to MATLAB Code, you created links between the requirements and the myAdd function that implements them, but the implementation status indicates that the requirements do not have implementation links. When you create links between requirements and MATLAB code, Requirements Toolbox sets the link type to Relate by default. The implementation status only checks for links with the type set to Implement.

Change Link Types

In the Requirements Editor, click Show Links. Select the first link in myAdd~m.slmx. In the right pane, under Properties, set Type to Implements.

Set the link type to Implements for the other links in the link set, then save the link set. View the updated implementation status by clicking Show Requirements.

The blue color of the implementation status bar indicates that the requirements are implemented. The tooltip for the implementation status indicates that four of the requirements in myAddReqs have implementation links.

Justify Exclusion of Test Requirements

Open the myAddTestSpecification requirement set in the Requirements Editor.

slreq.open("myAddTestSpecification");

The test requirements in myAddTestSpecification do not specify behavior for the functional design, and therefore do not need to be implemented. Justify their exclusion from the implementation status by linking each requirement to a justification. Right-click requirement 1.1 and select Justification > Link with new Justification for implementation.

Requirements Toolbox adds a justification hierarchy to the myAddTestSpecification requirement set. Repeat this step for requirements 1.2 and 2.1–2.4, then save the requirement set.

The light blue color of the implementatin status bar indicates that the requirements are jusitified for exclusion from the implementation status. The tooltip for the implementation status bar for the requirement set indicates that six of the eight requirements in the requirement set are justified for exclusion from the implementation status.

Change Requirement Types

For the implementation status, Requirements Toolbox checks implementation links for requirements that have the type set to Functional. In myAddTestSpecification, the requirements with summaries Validity checks and Functional tests act as containers for the test requirements. However, their types are set to Functional, so they are included in the implementation status. Change the requirement type for both requirements by selecting the requirement in the Requirements Editor, and, in the right pane, under Properties, setting Type to Container. Save the requirement set.

The Requirements Editor excludes the container requirements from the implementation status. The tooltip indicates that the six functional requirements in the requirement set are justified.
