JH thinks there could be interesting overlap. JH and DB had a chat during the meeting. To follow up at Ambleside.
SS to add this to Ambleside agenda. (perhaps will be discussed in more informal settings).

Daniela gave a brief background to this. All the information is in a ticket that she is going to send to AS.
AS to do some fact checking and perhaps speak with Tom Dack.
Need to try and agree in moving in the same direction.
Pick up on this when AD is back at the next meeting.
4) Industry Strategy Mapping
Email from STFC that Dave circulated to the group.
