I think an appropriate starting point might be to define what the specific circumstances are where government believes that it is inhibited from delivering efficient services because of what are often referred to as silos between departments that prevent information sharing. What are the practical problems? What do citizens actually want other than more efficient government generally? What kinds of services cannot be delivered efficiently in a timely way because of legal and bureaucratic impediments? I think that would be a start.
