[Css-csts] [CESG] Resolution CSS-R-2018-11-001

Thu Nov 29 15:37:51 UTC 2018

Dear Erik,
My reply was based on the last sentence of your resolution stating:
“…REQUESTS that the CCSDS Secretariat initiate polling for project 
creation”

The wording for that part of the resolution should have been , e.g. : 
“and REQUESTS that the CCSDS Secretariat initiate polling for project 
creation approval by CMC” 
 given that the Draft Project had been created in CWE (like you did). The 
relevant link should have been provided together with the resolution.

Concerning the Concept Paper, I am fully aware that it was addressed at 
the CESG meeting in Berlin, notably the issue with the “should” (not 
“shall”) in the Org and Procs books.
However, I consider that the changes to the CSTS Framework cannot be 
regarded as routine review, therefore I still recommend that a Concept 
Paper gets produced.

The fact that the CMC has been briefed on this upcoming new project is, in 
my view,  not suitable to help them in the approval decision. In fact, 
that kind of info is provided for many (granted, not all) new projects 
during a CMC meeting, and I assume  it would not be easy for CMC members 
to go back to the presentation(s) from previous meeting(s). The Concept 
Paper, instead, will be available to the CMC at the time of the Poll, 
providing all Project’s information. Also, the Concept Paper establishes 
the “boundary” of the changes, such that, after the project has been 
initiated, one cannot inject other changes that had not been agreed 
up-front (not happening normally, but sometimes it does). 
That said, I think that a Concept Paper – in the way it is envisaged in 
the Org & Porc - can  be produced in one hour of work by the author of the 
book, and it may consist of just one/two pages of text (see contents of 
Concept Paper at 6.1.3.2.1 of Org & Proc) .  Consequently, the effort 
required for producing that paper is not competing with the resources 
required for other activities.
Last (but not least) the kind of discussion we are having confirms what 
was addressed at the Berlin meeting, that is,  there may be changes 
required to the Org & Proc in order to come to a formulation of Concept 
Paper’ s requirements that will be shared by all CESG members. 
Kind regards
Margherita

Dear Margherita,

The draft project already exists (it was created on October 23rd) and can 
be found here:  
http://cwe.ccsds.org/fm/Lists/Projects/DispFormDraft.aspx?ID=667&Source=http://cwe.ccsds.org/fm/Lists/Projects/AllOpenChartersWithDraftProjects.aspx

The new project requires no resources as the work is already done.   Per 
the description in the draft project: “Updates needed to the CSTS 
Specification Framework (SFW) for supporting Forward Frame CSTS. This is a 
pink sheet/pink book update project. Per 2018 Spring Meetings and as noted 
during CESG report to CMC, prototyping for frame work updates will be 
covered by FF-CSTS prototyping.” The milestones are for the usual CCSDS 
review and publication cycles.

The Org and Procs books does not require a concept paper.   Here is what 
it says (“should”, not “shall”)

“…6.1.3.3.5 Concept papers defining new projects should be submitted to 
the AD as part of the project approval process and should be included with 
the materials provided during CMC polling…”

The CMC has been briefed on this as reported at the Spring 2018 meetings 
and also at the Fall 2018 meetings.  (Please see discussion about 
utilizing the FF-CSTS prototype to support prototyping the modifications 
need in the CSTS SFW – especially in the Spring 2018 presentation to CMC). 

Granted, this is technically a new project, but not conceptually.  I did 
not and do not think that updates to support FF-CSTS merit a concept paper 
as this is not defining any new concept, but rather technical adjustments 
to allow support for the behavior required for FF-CSTS. Therefore, 
assuming I have some discretion as an AD, my choice is not require this 
additional effort.  If you wish, I shall ask the working group chair to 
prepare a concept paper to submit to me so that I may review it per the 
Org and Procs as indicated above.   Please be advised that in the end it 
is CMC that approves projects, not CESG – as such I do not want to presume 
that CMC really want to read a concept paper.  I think a more productive 
course of action will be to ensure that currently in progress CSTS concept 
book has whatever minor sentence or two is needed.     Please advise if 
you still wish to have a concept paper.

Best regards,
-Erik

Dear Erik, 
you should  first create your draft project in the CWE Framework. The 
Project shall, between others, identify the resources required for the 
project -  in your case, the resources have already done the editing work. 
The dates for the various milestones shall be put very close to each other 
 for the part of the work that has already been done. Once completed the 
editing work, the Book will be submitted to Agency Review  (I assume this 
will be the Blue Book 2.). The relevant dates shall also be entered in the 
draft project. 
Also, you should determine if the new project requires resources for 
prototyping - depending on the kind of changes, it may be required to do 
delta-prototyping 

Once the draft project has been created, it will  be submitted to poll for 
CMC approval ( not CESG). 

Notice that every new project shall be be complemented by a "Concept 
Paper", as prescribed in  the Org & Proc book, 
(https://public.ccsds.org/Pubs/A02x1y4c2.pdf) 
This shall be a concise piece of  text, to outline the nature of the 
changes. Also, it shall  explain if, depending on the envisaged changes, 
prototyping is - or is not - required. 

In your resolution for CMC approval, please  provide : 
- the link to the draft project 
- the Concept Paper,  to make it available to the CMC to support their 
decision. 

Kind regards,
Margherita

 CCSDS Secretariat, CESG Chairs,

Attached and also listed below please find the resolution for the creation 
of a formal project for update of the CSTS Specification Framework.  Note 
that this is essentially a formality as the work to complete the updates 
for the CSTS Framework has already been completed.

Best regards,
-Erik

CSS-R-2018-11-001, Resolution concerning project creation for update of 
Cross Support Transfer Service – Specification Framework 

The CSS Area,

CONSIDERING that the CROSS SUPPORT TRANSFER SERVICE – SPECIFICATION 
FRAMEWORK, CCSDS 921.1-B-1, (“the recommendation”) is a published 
recommended standard of CCSDS;

and RECOGNIZING that the recommendation is the basis for Cross Support 
Transfer Services and therefore must be revised as new required service 
capabilities are identified;

and RECOGNIZING that the CSTS WG has completed revisions for the 
recommendation to support new service capabilities identified for the 
Forward Frame Cross Support Transfer Service;

and NOTING that, per the formal procedures of CCSDS that a project for 
updating the recommendation is needed; 

RESOLVES to create the formal project for update of the recommendation; 

and REQUESTS that the CCSDS Secretariat initiate polling for project 
creation.

[End Resolution]
