Various smaller teams comprising of members of the local working group are focusing on different activities that are of interest to them. These activity teams work independently and share updates of their work during regular meetings of of the MBSE Local Working Group. This allows members to work on activities of their interest. It also allows easier coordination and more frequent and focused interaction, given that the group is smaller.
You can refer to the 2021 Goals page for various activities that are being pursued. You can also find sub-pages in the menu for details of some current and past activities.
