RE: Report on Use of Orchestration/Choreography in NCOIC Members

[Ken Laskey <klaskey@mitre.org>]

Rex,

Thanks for the quick input.  Some questions come to mind:
1. How do the NCOIC folks interpret Figures 30 and 31?  Michael had some
particular concerns when applying this in his work.  Boris also had issues.
Can you get us any insight into how the NCOIC folks make use of this?
2. We didn't finish going through Michael's choreography mods but answer to
1 will help us determine what changes (either Michael's or otherwise) may be
useful and what needs to stay the same
3. My realization yesterday (maybe later than some of the group) that
Figures 30 and 31 may be useful in showing examples of compositions but I'm
not sure they really provide a useful illustration of the distinction we try
to make in the text.  If we need to keep Figures 30 and 31 pretty much as
they are, do we need additional models?

Ken

Hi Ken, Everyone,

I wanted to get word to you all immediately that we DO have multiple 
companies with internal implementations of the 
Orchestration-Choreography section in the NCOIC Services WorkGroup and 
the diagrams in particular, so I will be required to fight for retaining 
it with only the changes we discussed, and keep the diagrams with the 
minimal changes discussed. I don't have much concern that there will be 
pushback on our additional note that composition, especially in 
aggregations of multiple services will likely include orchestrations and 
choreographies in various combinations as needed.

I'm writing now because this feedback already convinces me to insist on 
keeping the diagrams. I have not yet asked the military audience, which 
I was most concerned about with the DoDAF Metamodel work. Our 
clarification of Activity as a collection of actions and joint actions 
is pretty certain to please that audience.

Sorry if this upsets any applecarts, but dropping the diagrams entirely 
would negatively impact the constituencies I work with most. We also 
need to specifically address the comment submitted by Dr. Allen Jones 
for Boeing.

Cheers,
Rex
