One suggestion I might have is that they hold round tables within their sessions or town halls within units. The leaders of those units can ask for specific feedback.
I think it could be part of a rating system of accountability. If there was feedback that came from that, one hopes it would be sincerely heard. It could be reflected to their superiors, and be reflected in some of the annual reporting and assessment tools that are used. If that's done, I think you'd hear real voices on the ground reflecting their clear views and being held accountable for delivery on that through the assessment process. That might be one way to help close the gap between policy and action.
