look like. </li><li class="yiv8771500886MsoListParagraph" style="margin-left:0in;">We will need to work with the SANA to see what is possible.</li></ul>

It also aligns with the definitions.</li><li class="yiv8771500886MsoListParagraph" style="margin-left:0in;">An example Mission Operations System (MOS) “swimlane” process flow was reviewed. This example starts with the reception of downlink telemetry, ends with uplinked commands, and uses
traditional commanding. Other approaches are possible.</li><li class="yiv8771500886MsoListParagraph" style="margin-left:0in;">Some adjustments to the diagram were made, on the fly<i>,

</li><li class="yiv8771500886MsoListParagraph" style="margin-left:0in;">Systems (in swimlanes) may be further decomposed into lower level systems elements.</li><li class="yiv8771500886MsoListParagraph" style="margin-left:0in;">Different sets of swimlanes may appear in different diagrams (higher, or lower, levels of details as well as different scope, like MOS/ground only or end-to-end.</li></ul>
</li><li class="yiv8771500886MsoListParagraph" style="margin-left:0in;">In the process of reviewing and updating the diagram we had to clarify some definitions of terms. The following is the current subset for this purpose:
