  <mainDescription>&lt;p>&#xD;
    The &lt;a class=&quot;elementLink&quot; href=&quot;./../../../core.mdev.common.extend_umf/guidances/concepts/umf_C03950A8.html&quot;&#xD;
    guid=&quot;_nrrn4GqHEdun45RPFGeYnA&quot;>Unified Method Framework (UMF)&lt;/a>&amp;nbsp;defines some constraints with regards to the&#xD;
    definition and use of &lt;a class=&quot;elementLink&quot;&#xD;
    href=&quot;./../../../core.default.uma_concept.base/guidances/termdefinitions/role_37A0C602.html&quot;&#xD;
    guid=&quot;_yUefQNnmEdmO6L4XMImrsA&quot;>role&lt;/a>s and &lt;a class=&quot;elementLink&quot;&#xD;
    href=&quot;./../../../core.default.uma_concept.base/guidances/termdefinitions/role_set_396DC9DB.html&quot;&#xD;
    guid=&quot;_Fs8HAMaIEduMlb2cQZNTYw&quot;>role set&lt;/a>s.&amp;nbsp;&#xD;
&lt;/p>&#xD;
&lt;p>&#xD;
    The UMF implements a delayed role assignment&amp;nbsp;approach, which means that the assignment of roles to method content&#xD;
    elements is NOT done as part of the definition of the method content elements.&amp;nbsp; In addition, in the UMF, role&#xD;
    definitions are intended to be shared.&amp;nbsp; Thus, in the UMF, the roles and role sets&amp;nbsp;are defined separately from&#xD;
    the method content elements they can be assigned to (e.g., work products and tasks), as well as from the assignments&#xD;
    themselves.&amp;nbsp; For information, see &lt;a class=&quot;elementLinkWithType&quot;&#xD;

    guid=&quot;_PPjo4PF3EdyPreM_8XDeJA&quot;>Guideline: Delayed Assignment in the UMF&lt;/a>.&#xD;
&lt;/p>&#xD;
&lt;p>&#xD;
    Roles and role sets may be shared across practices or may be practice-specific and this decision affects what plug-ins&#xD;
    their definitions and assignments are placed.&#xD;
&lt;/p>&#xD;
&lt;p>&#xD;
    Shared roles and role sets:&#xD;
&lt;/p>&#xD;
&lt;ul>&#xD;
    &lt;li>&#xD;
        Shared roles and role sets are &lt;strong>&lt;em>defined&lt;/em>&lt;/strong> in a Role Definition Base plug-in.&amp;nbsp;&#xD;
    &lt;/li>&#xD;
    &lt;li>&#xD;
        Shared roles are assigned to shared role sets in a Role Definition Base plug-in.&amp;nbsp;&#xD;
    &lt;/li>&#xD;
    &lt;li>&#xD;
        Shared roles are &lt;strong>&lt;em>assigned&lt;/em>&lt;/strong> to &lt;a class=&quot;elementLink&quot;&#xD;
        href=&quot;./../../../core.default.uma_concept.base/guidances/termdefinitions/task_6C1FF051.html&quot;&#xD;
        guid=&quot;_x459ktnmEdmO6L4XMImrsA&quot;>task&lt;/a>s and &lt;a class=&quot;elementLink&quot;&#xD;
        href=&quot;./../../../core.default.uma_concept.base/guidances/termdefinitions/work_product_826E4C22.html&quot;&#xD;
        guid=&quot;_H4JXwB_SEdq6CKKKq4D7YA&quot;>work product&lt;/a>s in the Assign plug-in associated with the Base plug-in where the&#xD;
        element to be assigned to the role (work product or task) is defined.&amp;nbsp;&#xD;
    &lt;/li>&#xD;
&lt;/ul>&#xD;
&lt;p>&#xD;
    Practice-specific roles and role sets:&#xD;
&lt;/p>&#xD;
&lt;ul>&#xD;
    &lt;li>&#xD;
        Practice-specific roles and role sets are defined in the Practice Assign plug-in.&#xD;
    &lt;/li>&#xD;
    &lt;li>&#xD;
        Practice-specific roles are assigned to practice-specific role sets in the Practice Assign plug-in.&amp;nbsp;&#xD;
    &lt;/li>&#xD;
    &lt;li>&#xD;
        Practice-specific roles are &lt;strong>&lt;em>assigned&lt;/em>&lt;/strong> to &lt;a class=&quot;elementLink&quot;&#xD;
        href=&quot;./../../../core.default.uma_concept.base/guidances/termdefinitions/task_6C1FF051.html&quot;&#xD;
        guid=&quot;_x459ktnmEdmO6L4XMImrsA&quot;>task&lt;/a>s and &lt;a class=&quot;elementLink&quot;&#xD;
        href=&quot;./../../../core.default.uma_concept.base/guidances/termdefinitions/work_product_826E4C22.html&quot;&#xD;
        guid=&quot;_H4JXwB_SEdq6CKKKq4D7YA&quot;>work product&lt;/a>s in the Practice Assign plug-in.&amp;nbsp;&#xD;
    &lt;/li>&#xD;
&lt;/ul>&#xD;
&lt;p>&#xD;
    The benefits to the UMF approach to roles are:&#xD;
&lt;/p>&#xD;
&lt;ul>&#xD;
    &lt;li>&#xD;
        Roles and role sets can be shared across practices (shared Role Definition plug-ins)&#xD;
    &lt;/li>&#xD;
    &lt;li>&#xD;
        Alternate role assignments can be defined (provide alternate Assign plug-ins)&#xD;
    &lt;/li>&#xD;
&lt;/ul>&#xD;
&lt;p>&#xD;
    Note: If you are developing a method where the role assignments can NEVER change, then late role assignment is overkill&#xD;
    and the role assignments can be done directly in Base plug-ins.&#xD;
&lt;/p>&#xD;
