    Traceability is about understanding how high-level requirements (objectives, goals, aims, aspirations, expectations,&#xD;
    needs) are transformed into low-level requirements, how they are implemented, and how they are verified.&#xD;
&lt;/p>&#xD;
&lt;p>&#xD;
    Using traceability can provide the following benefits &lt;a class=&quot;elementlinkwithusertext&quot;&#xD;

&lt;/p>&#xD;
&lt;ul>&#xD;
    &lt;li>&#xD;
        &lt;strong>Greater confidence in meeting objectives&lt;/strong>&#xD;
    &lt;/li>&#xD;
&lt;/ul>&#xD;
&lt;blockquote dir=&quot;ltr&quot; style=&quot;MARGIN-RIGHT: 0px&quot;>&#xD;
    &lt;p>&#xD;
        Establishing traceability engenders greater reflection on how objectives are satisfied.&amp;nbsp; Traceability permits&#xD;
        coverage analysis to ensure that everything you have done everything that you agreed to do and only what you agreed&#xD;
        to do.&#xD;
    &lt;/p>&#xD;
&lt;/blockquote>&#xD;
&lt;ul>&#xD;
    &lt;li>&#xD;
        &lt;strong>Ability to assess the impact of change&lt;/strong>&#xD;
    &lt;/li>&#xD;
&lt;/ul>&#xD;
&lt;blockquote dir=&quot;ltr&quot; style=&quot;MARGIN-RIGHT: 0px&quot;>&#xD;
    &lt;p>&#xD;
        Traceability permits various forms of impact analysis that can be used to assess the impact of a proposed change on&#xD;
        the cost, schedule, and technical aspects of the project.&#xD;
    &lt;/p>&#xD;
&lt;/blockquote>&#xD;
&lt;ul>&#xD;
    &lt;li>&#xD;
        &lt;strong>Improved accountability&lt;/strong>&#xD;
    &lt;/li>&#xD;
&lt;/ul>&#xD;
&lt;blockquote dir=&quot;ltr&quot; style=&quot;MARGIN-RIGHT: 0px&quot;>&#xD;
    &lt;p>&#xD;
        Traceability provides greater clarity about how work contributes to the whole.&#xD;
    &lt;/p>&#xD;
&lt;/blockquote>&#xD;
&lt;ul>&#xD;
    &lt;li>&#xD;
        &lt;strong>Ability to track progress&lt;/strong>&#xD;
    &lt;/li>&#xD;
&lt;/ul>&#xD;

    &lt;p>&#xD;
        It is notoriously difficult to measure progress when all that you are doing is creating and revising artifacts.&#xD;
        Traceability processes allow precise measures of progress, such as: Is there a design artifact for each&#xD;
        requirement? Is there a test case for each requirement?.&#xD;
    &lt;/p>&#xD;
&lt;/blockquote>&#xD;
&lt;ul>&#xD;
    &lt;li>&#xD;
        &lt;strong>Ability to balance cost against benefit&lt;/strong>&#xD;
    &lt;/li>&#xD;
&lt;/ul>&#xD;
&lt;blockquote dir=&quot;ltr&quot; style=&quot;MARGIN-RIGHT: 0px&quot;>&#xD;
    &lt;p>&#xD;
        Relating product components to the requirements allows you to compare benefits to costs.&#xD;
    &lt;/p>&#xD;
