    Description&#xD;
&lt;/h3>&#xD;
&lt;p>&#xD;
    The practice of collective ownership states that any member of the team can change any piece of code in the system at&#xD;
    any time.&#xD;
&lt;/p>&#xD;
&lt;p>&#xD;
    Having a good suite of tests and being able to integrate continuously is critical to ensuring that this practice works&#xD;
    well. Without the tests, it would be impossible to know that a critical piece of the system was modified improperly&#xD;
    because of inappropriate understanding. Integrating frequently and testing ensures that such problems are caught and&#xD;
    fixed quickly. Used with pair programming, collective code ownership is an effective way to spread the knowledge of the&#xD;
    system across the entire team.&#xD;
&lt;/p>&#xD;
&lt;h3>&#xD;
    Benefits&#xD;
&lt;/h3>&#xD;
&lt;ul>&#xD;
    &lt;li>&#xD;
        &lt;b>Shared knowledge of the code&lt;/b>: allows programmers to become familiar with more of the code and benefit from&#xD;
        the experience of others.&#xD;
    &lt;/li>&#xD;
    &lt;li>&#xD;
        &lt;b>Simpler code&lt;/b>: causes complex code to be found and refactored more quickly as many pairs of eyes read the&#xD;
        same code.&#xD;
    &lt;/li>&#xD;
    &lt;li>&#xD;
        &lt;b>Get things done quickly&lt;/b>: removes hurdles so changes can be made by those that need them when they need them.&#xD;
    &lt;/li>&#xD;
&lt;/ul></mainDescription>
