In my opinion, in this case the team is not just a group of people who have the same goal as you and doing common work with you.
but it is a group of people who are your clone .
If you act ,they act certainly , if you have a doubt, they also.
So At every welcome message, explain by choosing your words what you want to achieve with SFI stating your organizational constraints: time, resources to implement by you or others.
All the best on the way of success
