As an alternative, I suggest:

-the service manager and team have the authority to make decisions and only escalate when they need to

Really difficult to get rid of 'empowered' in principle 3, though, and I think if we did so, we'd be introducing extra words to try to explain it, when really, 'empowered' is the best way of doing so in that instance. I don't want to make a more complicated bullet just for the sake of avoiding a 'banned' word. 

This is an example of where I think it's sensible to flex the style guide a little - we've done it before on various services and parts of GOV.UK and I think we ought to just leave principle 3 as it is.
