[CMC] Interpretation of charter text and CSSA WG Charter

Wed Aug 1 11:31:29 EDT 2012

Dear Mike,

I have a comment. It is related to your phrase in the attached message:

The WG is authorized to begin work on the document *only after* after a project is also developed and submitted for a CMC poll (including resource estimates and agency agreements). 

Where I felt some apparent contradiction -between- the saying ... 

"to begin work on the document *only after*"

and the saying ...

"after a project is also developed"

In other words, there is an apparent contradiction between saying that a
work on a document is being proposed and that the corresponding project
has already been developed. 

But, my interpretation is wrong because you may have meant that a project 
may have already been developed -although- a work on a corresponding 
CCSDS document has not yet been written. If so, please, just confirm me.

Changing to another aspect of the whole issue. A suggestion is being made.,
as follows, for your and CMC possible consideration.

The Charter could only, although very firmly and to the best of precision 
in its assertions, (very) clearly declare a list-of-topics (or other name) 
which are proposed to be (firmly) covered by the WG. 

The mentioned (firm) list-of-topics (or like) would, tentatively, reflect a
firm intention to have, each of them, as directly correspondents to future
CCSDS books, which would be expected to be produced and delivered as 
CCSDS  products, by the WG. 

However, it would be implicitly acceptable under the terms of the Charter
that each of items of the list-of-topics may or may not become a
book of the type: Blue, Magenta, Green, or else. 

On the other hand, the WG Program-of-Work and associated scheduling, 
since its very first version, would (as usual) express or declare in clear 
terms what are the deliverables (products) which are under consideration 
as work items and, additionally, also since the beginning, what is the 
planned or intended nature for each of the programmed deliverable, i.e., a 
BB, MB, GB, or else. 

In principle, it would be acceptable that at some point in time, the WG may, 
after a plausible justification, decide in a definitive fashion to change 
the nature (BB, MB, GB or else) of one or other of the scheduled work item 
deliverables.

Thank you for the opportunity.

With my best regards,
Eduardo
INPE/CCSDS

Subject: [CMC] Interpretation of charter text and CSSA WG Charter

Dear CMC members:   

There has been some concern with the text of this proposed charter, expressed by Martin Pilgram in his provisions, and also from me when I first read this charter.  The charter lists in the text that the CSSA WG will develop certain books, and this change adds a new book, a "concept" Green Book.  However, there is no project added to the Framework for this, and no resources indicated.   

http://cwe.ccsds.org/fm/Lists/Charters/DispForm.aspx?ID=49

I propose this interpretation.   

When there is text in a charter saying what books will be developed, this is a "scope" statement only.  It says that the scope of work of the working group is allowed to be broad enough to include the creation of these types of books, or these book titles.  But that only is intended to bound the scope of the working group, not to authorize work to begin on the books.   

The WG is authorized to begin work on the document *only after* after a project is also developed and submitted for a CMC poll (including resource estimates and agency agreements).  

Therefore, the text of this charter is OK to be approved if the other aspects are OK to the CMC members.  The WG chair is naturally wanting the CMC to confirm that this overall scope is OK before he puts effort into developing the project plan for the document.  If the CMC approves this scope, then he will develop the project plan (schedule, resources) and then submit it to the CMC for approval.   

I considered other possibilities.  We could forbid the mention of books in the charter, only in the project.  But that makes it more difficult to understand the intended scope of the WG.  Or, we could absolutely require that no charter scope is approved unless the accompanying projects are approved at the same time.  But that may cause unnecessary work for the WGs in the case that we disagree with the scope.  So I think the interpretation above is best.  

Unless we hear some objections from the CMC members, we will explain this interpretation to the WG chairs via the CESG-all mail list.  

Also, we still do not have enough votes on this document (below) to pass the charter.  If you have not yet voted, please vote soon.
