Tricky. Here are some ideas: 1 involve them in defining that common mission you mention 2 sounds like you are at least temporarily pretty involved in the backend work. Take some time with the frontend people to understand their world, concerns, things you can do to make their lives easier 3 if the work is that separate, I would not insist on frequent joint planning/ stand ups. But make sure that this doesn’t backfire “we are already unimportant, now they don’t even want us at the stand up”
