Developing 'smart cities' is about so much more than a bunch of 'cool tech' projects - as with other expected changes we see coming in government, it's about fully rethinking how we deliver services, and even what services are most appropriate. 

One of the structures that will make this ambitious transformation possible is the public-private partnership. The 'partnership' is the key - and it's all about a clear focus on delivering the planned ROI, however you agree it's defined, and doing it together. 

Another key point in this article is that of doing the work of the partnership in stages - deliver on the first stage of benefits, reassess the partnership, and if it works, define another stage. This is a different sort of partnership than the traditional arms-length government/vendor relationship, but one I think will make possible so many of the necessary transformations we are starting to see coming.
