[SLS-CC] C&S - Progress meeting

Fri Feb 28 13:01:26 UTC 2025

Hi all,
With reference to the C&S progress meeting organization, it is confirmed Friday April 11, at the following time

17:00-19:00 Amsterdam
8:00-10:00 Los Angeles
11:00-13:00 DC

Invitation was sent some days ago. In case you did not receive it, you can find it in attachment.

For the organization, I propose again the simplified version of last time, that looked more suited for the telco, i.e..,

  *   Review of AIs list
  *   For each item, the actionee can either:
     *   Provide an input (as in normal meetings), or
     *   Debrief the status of the AI (even verbally is fine) for discussing possible open points, doing brainstorming, or simply give an educated guess by when the AI will be closed
  *   Inputs shall not be announced and provided in advance, unless you require the WG to take a look beforehand (e.g., detailed analysis, new topic, etc.)
  *   Just in case you believe your AI discussion should take more than 15 mins, please let me know a few days before meeting, for adapting the planning (in general, I expect that AI_24_17 and AI_24_18 on Prox-1 can take more, while others will be more status update)

For your convenience I attach latest list of AIs, that can also be retrieved from https://tinyurl.com/CSactionItemList

Regards,
Andrea

Subject: C&S - Progress meeting

Hi all,
I have seen this year CCSDS will be almost a "Summer" meeting , and it appears in time overlap with SFCG (10-18 June).
We had also an initial plan was to have a progress meeting in February,  but this is pending the ongoing AIs on Proxy-1.

Considering the situation, I would like to postpone the remote progress meeting on Friday April 11, at the following time

17:00-19:00 Amsterdam
8:00-10:00 Los Angeles
11:00-13:00 DC

With the following objectives:
-review Proxy-1 status of activities (of interest also for RFM/SLP)
- anticipate inputs that do not need to wait Spring meeting (useful also for those that may unable to attend it)

For those that the slot does not work, could you let me know?
(few absences are fine, but in case of large majority, I check for a new slot or set a doodle)
