That is precisely the point. Leave them alone to do their job but with an eye on the progress/results and if they seem to be straying, nudge them back onto the path. Do not micromanage; any exceptions have to be dealt with on a case-by-case basis.
Delegate responsibility, Clarify deliverables, Request regular progress reports but at the same time give them the Freedom and Autonomy to do their job their own way.
