Latest update: The team have met to review existing documentation.

The SDO needs updating as follows:

1. Slides 2 and 3: Paul to review and update
2. Slide 4: Paul to replace with something less confusing to those not involved in its creation. NB: Slides 3 and 4 should collectively explain why we are presenting, what problem we are solving and high-level how we are going about it.
3. Slide 5: @COX, Bob (NHS DIGITAL) to arrange for it to be replaced with a draft technical high-level design. If scribe support is required, please speak to Paul. It’s noted that any first draft will be incomplete as there are known gaps as the final architectural solution is still evolving as we resolve problems.
4. New Slide (6): New process diagram required to explain how Mauro interacts with the satellite components developed for the Data Dictionary instance. @COX, Bob (NHS DIGITAL) to speak to David B to get his support then David, @CHILCOTT, Cath (NHS DIGITAL)/@FAULDING, Angela (NHS DIGITAL) to develop the new slide

KADs

5. We do not currently believe that any KADs are required, but will review when we have a first draft of the documentation above.

David Burden is assigned to work on the diag. of DD publication. Bob C.is working on this with Paul C.

[PaulChapmanPM]

Thanks for updating this. By the way I checked with Bob whether he wanted allocating to the ticket and he said he’d manage his team’s activities via their board, so no need to allocate him (in case you were wondering)

My actions from 26 Jan: Slides 2 and 3: Paul to review and update Slide 4: Paul to replace with something less confusing to those not involved in its creation.
