<ul style="margin-top:0in" type="disc">
<li class="MsoNormal" style="color:black;mso-list:l1 level1 lfo1">Review the two existing SC14 spreadsheets that represent its plan of work: a spreadsheet showing all of the projects, one line per document, showing the WG responsible, and a PDF file from Akiro-san
that sorts the documents according to what might be described as “categories”, as in “ICD”, “SE”, “Management”, “Design”, “Operations”, and “Debris/disposal”. Akiro-san’s categories tend to be topical: environment, launch, I&T, etc.<o:p></o:p></li><li class="MsoNormal" style="color:black;mso-list:l1 level1 lfo1">In the Project Spreadsheet Fred has added four new columns: “Element”, “Tier”, “Viewpoint”, and “Technical Area”, with the intent of providing the means to tag each of these standards as to what
role they play along these different dimensions:<o:p></o:p>
<ul style="margin-top:0in" type="disc">
<li class="MsoNormal" style="color:black;mso-list:l1 level2 lfo1">Element: space, ground, launch, or some combination thereof<o:p></o:p></li><li class="MsoNormal" style="color:black;mso-list:l1 level2 lfo1">Tier: Mission, Segment, System, Subsystem, Unit, Assembly, materials<o:p></o:p></li><li class="MsoNormal" style="color:black;mso-list:l1 level2 lfo1">Viewpoint: Physical, Operational, Enterprise, Functional, …<o:p></o:p></li><li class="MsoNormal" style="color:black;mso-list:l1 level2 lfo1">Technical Area (maybe really ISO 15288 “Stage”): Mgmt, Design, Engineering, I&T, V&V, Operations<o:p></o:p></li></ul>
</li><li class="MsoNormal" style="color:black;mso-list:l1 level1 lfo1">We reviewed some of the specific documents and how they appeared in each spreadsheet. The set of docs was: 22009 (model of Earth’s magnetic field, largely Physical VP in RASDS ++), 16457 (Earth’s
ionosphere, much the same as 22009), 17689 (ICD between ground elements and launch vehicle, largely Physical technical & operational), and 18146 (space debris mitigation design and operation guidelines, mostly Physical VP, but also with design and operational
elements).<o:p></o:p></li><li class="MsoNormal" style="color:black;mso-list:l1 level1 lfo1">It became clear (at least to us) that the four categories that Fred had proposed provided a finer grained characterization of these documents.
<o:p></o:p></li><li class="MsoNormal" style="color:black;mso-list:l1 level1 lfo1"><b><i>=> Action Item</i></b>: Fred has agreed to look at this in some detail and to review it with the nascent SC14 architecture team. Fred will report back during a future meeting.<o:p></o:p></li><li class="MsoNormal" style="color:black;mso-list:l1 level1 lfo1"><b><i>=> Action Item</i></b>: agree to incorporate in the early sections of the RASDS++ update a description of the concepts that power Fred’s additions to that spreadsheet. Definitions of
the terms “stage”, “tier”, Tech area” will be briefly introduced, because will reference them in the revised Enterprise VP, along with a recommendation for a project that uses RASDS++ to adopt, and carefully define, their own terms and meanings. Note that
different orgs may well use different terms.<o:p></o:p></li></ul>

project<o:p></o:p></li><li class="MsoListParagraph" style="color:black;mso-list:l2 level1 lfo6">Discussed the set of proposed definitions of operations terms. Christian pointed out that the European agencies may have a different set of terms.<o:p></o:p></li><li class="MsoListParagraph" style="color:black;mso-list:l2 level1 lfo6"><b><i>=> Action Item</i></b>: everyone is to review these terms, on pgs 8 & 9, and either concur, or provide some other self consistent set of definitions and relationships for these
Operations VP terms.<o:p></o:p></li><li class="MsoListParagraph" style="color:black;mso-list:l2 level1 lfo6">Reviewed the Functional VP and Operational / Actitivity VP diagrams on pgs 11-13. General agreement on what they represent and how they do it. There may, or may not, need to be some
distinction drawn re whether the terms should be different, I.e., M<u>an</u>euever Design (function) vs Maneuver Design Process<o:p></o:p></li><li class="MsoListParagraph" style="color:black;mso-list:l2 level1 lfo6">We reviewed the “singing and dancing” pairs of diagrams, pgs 14-18, where the functions from the functional view are numbered and matched with the activity view and animated step by step<o:p></o:p></li><li class="MsoListParagraph" style="color:black;mso-list:l2 level1 lfo6">Peter agreed that these “singing and dancing” pair diagrams, would be more effective that way, but declined to expend the resources to do that. It’s a task “left for the student”.<o:p></o:p></li></ul>

Peter asked if there were other major items that we needed to address in the current set of VP under discussion.
<o:p></o:p></li><li class="MsoNormal" style="color:black;mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l3 level1 lfo3">
General agreement that we have covered the Enterprise and Operational topics as far as coverage, and that the details of Engineering VP and Mission Assurance are to be left to the existing ISO 15288 and related agency engineering specs. There is no benefit
in trying to revisit these rather well understood topics. We will just point to these other docs.<o:p></o:p></li><li class="MsoNormal" style="color:black;mso-margin-top-alt:auto;mso-margin-bottom-alt:auto;mso-list:l3 level1 lfo3">
