Use different rooms (with relavent people in each room), or make your bot smarter (we do both). You could easily make it so a given user could 'subscribe' to a project by sending a message to the bot. i.e. '@companybot subcribe xyz-service'. Then have the bot keep track of those and automatically at-message the interested people upon failures etc. IMO opinion, different rooms are still better, because it brings everyone together when there's an issue also, but it depends how large an organization you have.
