    This task&amp;nbsp;builds on&amp;nbsp;the work&amp;nbsp;performed during&amp;nbsp;&lt;a class=&quot;elementLinkWithType&quot; href=&quot;./../../openup/tasks/outline_the_architecture_FF123A81.html&quot; guid=&quot;_0f-1oMlgEdmt3adZL5Dmdw&quot;>Task: Outline the Architecture&lt;/a>.&amp;nbsp;The objective is to&amp;nbsp;make the architectural&#xD;
&#xD;
    decisions necessary to support the objectives for the current iteration of the project. The decisions&amp;nbsp;taken as&#xD;
&#xD;
    part of this task&amp;nbsp;are concrete and unambiguous. They are captured in the &lt;a class=&quot;elementLink&quot; href=&quot;./../../openup/workproducts/architecture_notebook_9BB92433.html&quot; guid=&quot;_0XAf0MlgEdmt3adZL5Dmdw&quot;>Architecture Notebook&lt;/a>&amp;nbsp;and communicated across the team.&#xD;

&lt;p>&#xD;
&#xD;
    This task is applied iteratively; iterations after the first will need to take account of the &lt;a class=&quot;elementLink&quot; href=&quot;./../../openup/workproducts/design_D677D182.html&quot; guid=&quot;_0WuL8slgEdmt3adZL5Dmdw&quot;>Design&lt;/a>&amp;nbsp;and &lt;a class=&quot;elementLink&quot; href=&quot;./../../openup/workproducts/build_95D7D8FD.html&quot; guid=&quot;_0YuXEMlgEdmt3adZL5Dmdw&quot;>Build&lt;/a>&amp;nbsp;products that have been developed so far.&#xD;

    required to prove the architecture.&amp;nbsp;During the early stages of the project it may be&amp;nbsp;acceptable for the&#xD;
    software to have a incomplete or prototypical feel, as it&amp;nbsp;will be&amp;nbsp;primarily concerned with baselining the&#xD;

    motivation and objectives related to the&amp;nbsp;decisions that have been made in shaping the architecture. This will make&#xD;

  <keyConsiderations>&lt;p>&#xD;
&#xD;
    The architect should perform this task&amp;nbsp;through collaboration with the whole&amp;nbsp;team to promote consensus and a&#xD;
&#xD;
    common understanding of the overall solution. The architect should be working to coordinate and guide the technical&#xD;
&#xD;
    activities of the team, rather than seeking to do all the work alone.&amp;nbsp;The architect should place emphasis&amp;nbsp;on&#xD;
&#xD;
    involving&amp;nbsp;the developer(s) throughout this task.&#xD;
